Floating in the Dead Sea ...You Can't Sink!
The Dead Sea (Hebrew: יָם הַמֶּלַח, Yam ha-Melah, "Sea of Salt", also Hebrew: יָם הַמָּוֶת, Yam ha-Mavet, "The Sea of Death", and Arabic: البحر الميت‎‎ About this sound Al-Bahr al-Mayyit (help·info)), also called the Salt Sea, is a salt lake bordered by Jordan to the east and Israel and Palestine to the west. Its surface and shores are 429 metres (1,407 ft) below sea level, Earth's lowest elevation on land. The Dead Sea is 304 m (997 ft) deep, the deepest hypersaline lake in the world. With 34.2% salinity (in 2011), it is 9.6 times as salty as the ocean, and one of the world's saltiest bodies of water. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea is 50 kilometers (31 mi) long and 15 kilometers (9 mi) wide at its widest point. It lies in the Jordan Rift Valley and its main tributary is the Jordan River. The Dead Sea water has a density of 1.24 kg/liter, which makes swimming similar to floating. Biblical period- Dwelling in caves near the Dead Sea is recorded in the Hebrew Bible as having taken place before the Israelites came to Canaan, and extensively at the time of King David. Just northwest of the Dead Sea is Jericho. Somewhere, perhaps on the southeastern shore, would be the cities mentioned in the Book of Genesis which were said to have been destroyed in the time of Abraham: Sodom and Gomorra (Genesis 18) and the three other "Cities of the Plain", Admah, Zeboim and Zoar (Deuteronomy 29:23). Zoar escaped destruction when Abraham's nephew Lot escaped to Zoar from Sodom (Genesis 19:21-22). Before the destruction, the Dead Sea was a valley full of natural tar pits, which was called the vale of Siddim. King David was said to have hidden from Saul at Ein Gedi nearby. In Ezekiel 47:8-9 there is a specific prophecy that the sea will ".. be healed and made fresh", becoming a normal lake capable of supporting marine life. A similar prophecy is stated in Zechariah 14:8, which says that "Living waters will go out from Jerusalem, half of them to the eastern sea (likely the Dead Sea) and half to the western sea (the Mediterranean)..." Greek and Roman period- Aristotle wrote about the remarkable waters. The Nabateans and others discovered the value of the globs of natural asphalt that constantly floated to the surface where they could be harvested with nets. The Egyptians were steady customers, as they used asphalt in the embalming process that created mummies. The Ancient Romans knew the Dead Sea as "Palus Asphaltites" (Asphalt Lake). King Herod the Great built or rebuilt several fortresses and palaces on the western bank of the Dead Sea. The most famous was Masada, where in 70 CE a small group of Jewish zealots fled after the fall of the destruction of the Second Temple. The zealots survived until 73 CE, when a siege by the X Legion ended in the deaths by suicide of its 960 inhabitants. Another historically important fortress was Machaerus (מכוור), on the eastern bank, where, according to Josephus, John the Baptist was imprisoned by Herod Antipas and died. Also in Roman times, some Essenes settled on the Dead Sea's western shore; Pliny the Elder identifies their location with the words, "on the west side of the Dead Sea, away from the coast ... [above] the town of Engeda" (Natural History, Bk 5.73); and it is therefore a hugely popular but contested hypothesis today, that same Essenes are identical with the settlers at Qumran and that "the Dead Sea Scrolls" discovered during the 20th century in the nearby caves had been their own library. Josephus identified the Dead Sea in geographic proximity to the ancient Biblical city of Sodom. However, he referred to the lake by its Greek name, Asphaltites. Various sects of Jews settled in caves overlooking the Dead Sea. The best known of these are the Essenes of Qumran, who left an extensive library known as the Dead Sea Scrolls. The town of Ein Gedi, mentioned many times in the Mishna, produced persimmon for the temple's fragrance and for export, using a secret recipe. "Sodomite salt" was an essential mineral for the temple's holy incense, but was said to be dangerous for home use and could cause blindness. The Roman camps surrounding Masada were built by Jewish slaves receiving water from the towns around the lake. These towns had drinking water from the Ein Feshcha springs and other sweetwater springs in the vicinity. Byzantine period- Intimately connected with the Judean wilderness to its northwest and west, the Dead Sea was a place of escape and refuge. The remoteness of the region attracted Greek Orthodox monks since the Byzantine era. Their monasteries, such as Saint George in Wadi Kelt and Mar Saba in the Judean Desert, are places of pilgrimage.

Dead Sea In Jordan - The Deepest Salt Lake In The World
The Dead Sea also called the Salt Sea, is a salt lake bordering Jordan to the east and Israel and the West Bank to the west. Its surface and shores are 423 metres (1,388 ft) below sea level, Earth’s lowest elevation on land. The Dead Sea is 377 m (1,237 ft) deep, the deepest hypersaline lake in the world. With 33.7% salinity, it is also one of the world’s saltiest bodies of water, though Lake Assal (Djibouti), Garabogazköl and some hypersaline lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond) have reported higher salinities. It is 8.6 times saltier than the ocean. This salinity makes for a harsh environment in which animals cannot flourish, hence its name. The Dead Sea is 67 kilometres (42 mi) long and 18 kilometres (11 mi) wide at its widest point. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River. The Dead Sea has attracted visitors from around the Mediterranean basin for thousands of years. Biblically, it was a place of refuge for King David. It was one of the world’s first health resorts (for Herod the Great), and it has been the supplier of a wide variety of products, from balms for Egyptian mummification to potash for fertilizers. People also use the salt and the minerals from the Dead Sea to create cosmetics and herbal sachets. In 2009, 1.2 million foreign tourists visited on the Israeli side.

Why is the ocean salty?
Ever wonder why the ocean is salty? The reasons we are discussing today as why the ocean is salty are: • The ability of water to dissolve salts • The source of salt in the ocean, such as rivers and the earth’s interior. • Just how salty is the ocean? • The components that make up the salt in the ocean • Does the level of salt in the ocean change?

5 Strangest Ocean Phenomena You Won't Believe!
5 Strangest Ocean Phenomena You Won't Believe! Description: If you thought the ocean is only valuable for your surfing expeditions, you my friend are missing a whole world of beauty! The vastness of the ocean means that you are sure to find mind boggling and intriguing phenomenon. Analysts and experts have really helped us understand most of these fascinating facts but still, some of these cannot really be rationalized. I envy the sailors who witness and experience this phenomenon. Let’s see what they see as we look at these 5 Strangest Ocean Phenomena You Won't Believe! Lets begin! 1. Milky Sea Phenomenon Several generations are proof to this spectacle. The Milk Sea phenomenon takes place in the Indian Ocean. It is quite similar to the bioluminescence that happens in various parts of oceanic water all around the world. The explanation to this is bacterial action that makes a large amount of the sea water to change to a blue color which then appears to turn milky in color to the human eye. This occurrence is so vast and prominent such that it can be seen all the way from space. Maybe we should try to catch the next space shuttle to out of space. 2. Bioluminescence Beauty is a characteristic of the ocean. If you think I am messing with you, consider bioluminescence. By far, this the coolest of all the oceanic phenomenon that happen. Bioluminescence occurs when light emitted from a living organism combines with atmospheric oxygen. The result: a chemical reaction of light energy and boom! It usually seems like the entire ocean is lit up, kind of like huge beams submerged in the water. In the night, the view is usually spectacular. Now imagine that during a starry night. Best sight ever! 3. The Rogue Wave Any sailor will tell you that sight and sound are very important in the identification of a wave. Rogue waves, however, do not to follow this rule. This wave forms almost out of thin air and gives no warning of its occurrence. It has even baffled the weathermen. Rogue waves occur far from any land and are of a colossal variety, reaching up to 80 feet high. If you ask any sailor who has experienced this, they will tell you the ship is the last place you want to be at that moment. The waves are mysterious, monstrous, deep and dark. Next time you want to venture to the middle of the ocean, you may want to reconsider. 4. Frost Flowers If nature has ever been artistic in its lifetime it has to be through frost flowers. These flowers are often found forming in the colder seas where very little wind blows. The ice clusters will grow around 4 centimeters in diameter and take on the shape of a flower. They get their beautiful shape because of the high salt content which is very important for crystallization. The flowers also create salinity into the air wherever they form in the sea. Now that’s artistic! 5. Red Tide What comes in strong vivid colors of red and orange with lace tides as they arrive at the beach? You guessed it…the red tide. It is quite a beauty if you ask me. Before you go all ‘Aww” about it, the cause of this tide is quite dangerous. The cause of these waves are harmful algal blooms that grow exponentially, such that they start producing toxic and harmful chemicals. These chemicals are bad for marine animals, fish, birds and people. This notoriously takes place every summer along the Florida Gulf Coast. So, next time you see something like that, just enjoy the scene from afar. Do not…I repeat…Do not come too close.

Barrier between Sweet and Salty Waters | Miracles of the Quran | Subtitled
Help Fund this Series: https://www.launchgood.com/MiraclesofQuran BARRIER BETWEEN SWEET AND SALT WATERS Consider the following Qur’aanic verses: “He has let free the two bodies Of flowing water, Meeting together: Between them is a Barrier Which they do not transgress.” [Al-Qur’aan 55:19-20] In the Arabic text the word barzakh means a barrier or a partition. This barrier is not a physical partition. The Arabic word maraja literally means ‘they both meet and mix with each other’. Early commentators of the Qur’aan were unable to explain the two opposite meanings for the two bodies of water, i.e. they meet and mix, and at the same time, there is a barrier between them. Modern Science has discovered that in the places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity and density. Oceanologists are now in a better position to explain this verse. There is a slanted unseen water barrier between the two seas through which water from one sea passes to the other. But when the water from one sea enters the other sea, it loses its distinctive characteristic and becomes homogenized with the other water. In a way this barrier serves as a transitional homogenizing area for the two waters. This scientific phenomenon mentioned in the Qur’aan was also confirmed by Dr. William Hay who is a well-known marine scientist and Professor of Geological Sciences at the University of Colorado, U.S.A. The Qur’aan mentions this phenomenon also in the following verse: “And made a separating bar between the two bodies Of flowing water?” [Al-Qur’aan 27:61] This phenomenon occurs in several places, including the divider between the Mediterranean and the Atlantic Ocean at Gibralter. But when the Qur’aan speaks about the divider between fresh and salt water, it mentions the existence of “a forbidding partition” with the barrier. “It is He Who has Let free the two bodies Of flowing water: One palatable and sweet, And the other salty and bitter; Yet has He Made a barrier between them, And a partition that is forbidden To be passed.” [Al-Qur’aan 25:53] Modern science has discovered that in estuaries, where fresh (sweet) and saltwater meet, the situation is somewhat different from that found in places where two seas meet. It has been discovered that what distinguishes fresh water from salt water in estuaries is a “pycnocline zone with a marked density discontinuity separating the two layers.” This partition (zone of separation) has salinity different from both the fresh water and the salt water. This phenomenon occurs in several places, including Egypt, where the river Nile flows into the Mediterranean Sea. A series exploring 1000s of Miracles of Quran that recent advancements has been able to decipher so far. Each of them might be possible by sheer human luck, but to get these 1000s of Miracles correctly in a single book that was not edited after it produced is truly another proof of divinity of Quran. ► Subscribe: https://bit.ly/2P3PvJY ► Learn Arabic The Easiest Way: https://bit.ly/2KKZjpD ► Become Patron: https://www.patreon.com/DarulArqam ► Give one time donation: https://bit.ly/2MEtBQX ► Help us translate our videos into other languages: https://bit.ly/2osd8Re Watch FreeQuranEducation in other Languages: ►Azerbaijani: https://bit.ly/2MIfcmD ► Urdu/Hindi: https://bit.ly/2gD86NO ►Turkish: https://bit.ly/2i4etdp ►Indonesian: https://bit.ly/2y4GSLd ►Pushto: https://bit.ly/2NG2QId ►French: https://bit.ly/2PViXD7

Salt Damp. What is it? How does it occur?
Salt Damp or Rising Damp is a common problem in South Australia. A combination of weather, soil salinity, high water tables and masonry buildings has meant that we have one of the highest incidences of damp and subsequent salt damage to our walls. But what exactly is it? Where does the moisture come from? Why is mortar missing between my bricks?

Salt Nacl mineral Making Process Naturally | How to make Sea crystalline Salt Chemistry Preparation
Common salt or Table salt is a mineral composed mainly of sodium chloride (NaCl), a chemical compound belonging to the highest class of salts; Salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in large quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter, a salinity of 3.5%. Salt is essential for life in general, and salinity is one of the basic human tastes. Animal tissues contain greater amounts of salt than plant tissues. Salt is one of the oldest and most ubiquitous foods, and salting is an important method of preserving food.
Amazing!! Where the Baltic and North Seas meet
Amazing!! Where the Baltic and North Seas meet all about this channel in here https://goo.gl/D1zMrA In the resort town of Skagen you can watch an amazing natural phenomenon. This city is the northernmost point of Denmark, where the Baltic and North Seas meet. The two opposing tides in this place can not merge because they have different densities. The province of Skagen located in Denmark has witnessed the beauty of the convergence of the two seas. It is characterized by a clear line which separates the two water and shows a magnificent display of natural beauty. Also mentioned in holy Koran, this sea meet is due to the difference in density of both sea waters which appear as adividing line on the ocean. There is a clear difference in the color of the waters coming from two different seas. At the headland at Grenen, the northernmost point of Denmark, the North Sea and the Baltic Sea meet. Because of their different densities, a clear dividing line can be seen. As a result of turbulent seas, beachings and shipwrecks were common.These frequent losses combined with the town's strategic location as the gateway to the Baltic led to Skagen being the site of one of Denmark's earliest lighthouses.

It is the 2nd deepest lake with point being 1470 m below surface level. 5} Michigan Lake-58,000 sq.Km Michigan lake is largest lake contained within one country (North America). By volume, it is the 2nd largest in world with 4,918 sq.Km of water. 4} Huron Lake -59,600 sq.Km Huron lake is the world’s 4th largest lake and the 3rd largest fresh water lake. It Contains Manitoulin Island and it is the world's largest lake island. 3} Victoria Lake-68,870 sq.Km Victoria lake is the largest lake by area in Africa. It is the world’s largest tropical lake, and as the 2nd largest fresh water lake, covering a total surface area of 69,485 square kilometers. 2} Superior Lake -82,100 sq.Km Superior Lake Considered the largest freshwater lake in world by surface area and third-largest freshwater lake in world by volume. According to shipwreck historian Frederick Stonehouse, the southern shore of Lake Superior between Grand Marais, Michigan, and Whitefish Point is known as the "Graveyard of the Great Lakes" and more ships have been lost around the Whitefish Point area than any other part of Lake Superior. 1} Caspian Sea*- 436,000 sq.Km Caspian Sea has been listed as the world's largest lake, although it is not a freshwater lake. It has characteristics common to both seas and lakes. Deepest part of the lake is 1,025 m and stands 3rd-deepest lake in the-world. Its the only Oceanic Lake. This is because rather than being entirely over the continental crust, the Caspian Sea has an Oceanic Basin. It also is an “endorheic basin”, referring to it being a closed system with no outflows. The salinity of lake is approximately 1.2%, about a third of the salinity of most seawater.

मृत्य सागर क्या है?what is dead sea?
Namste doston ...People do not sink in the Dead Sea because of the high salinity of the water. The high salt content leads to high density of the water. The density is higher than that of the humans, because of which we float and not sink. Dead Sea also known as Sea of Salt or Salt Sea, situated in the Jordan Rift Valley is the deepest saline sea on earth. Jordan River is the major water supplier of the Dead Sea. It is also the world's saltiest water body with the salinity of 34.2%. And the name Dead Sea has been given for this extreme salinity of the water due to which no animal can thrive in this sea. The water of Dead Sea is having the density of 1.240kg/L due to which swimming in Dead Sea is almost synonymous to floating. That is why it is said that nobody ever drowns in the Dead Sea. It is worthy of mentioning in this connection that the Great Salt Lake in America is also similar to Dead Sea in this respect. Dead Sea is situated about 420 meters or 1385 feet below the sea level . The amount of water which evaporates from this sea is more than the amount of water that flows through it. This is because its water has got the highest quantity of concentrated salt in it which amounts to as high as nearly 350 grams per litre. The Dead Sea is considered the saltiest water body existing on earth with a salinity of 33.7%. Although Lake Assal (Djibouti), Garabogazkol and some hypersaline lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond) have reported higher salinity.The Dead Sea is the deepest of all hyper-saline lakes on earth. And by "Hyper-saline Lake" we mean a body of water which is having greater amount of sodium chloride and other salts that exceeds the normal saline level of ocean water. subscribe here https://www.youtube.com/channel/UCiCCZUI25PiUbD8CPD9DaEw like our Facebook page https://facebook.com /innovativeapproach follow us on Instagram https://Instagram.com/innovativeapproach follow us on google plus https://googleplus.com/innovativeapproach -~-~~-~~~-~~-~-

Aral Sea Catastrophe
Death of Aral Sea, winds rise and spread the bottom salt on hundreds of kilometers around. Aral a once-large saltwater lake straddling the boundary between Kazakstan to the north and Uzbekistan to the south. The shallow Aral Sea was formerly the world's fourth largest body of inland water. It nestles in the climatically inhospitable heart of Central Asia, to the east of the Caspian Sea. The Aral Sea is of great interest and increasing concern to scientists because of the remarkable shrinkage of its area and volume in the second half of the 20th century. This change is due primarily to the diversion (for purposes of irrigation) of the riverine waters of the Syr Darya and Amu Darya, which discharge into the Aral Sea and are its main sources of inflowing water. The sea's northern shore—high in some places, low in others—was indented by several large bays. The low-lying and irregular eastern shores were interrupted in the north by the huge delta of the Syr Darya and in the south were bordered by a wide tract of shallow water. The equally vast Amu Darya delta lay on the lake's southern shore, and along the lake's western periphery extended the almost unbroken eastern edge of the 820-foot- (250-metre-) high Ustyurt Plateau. Shrinkage of the Aral Sea, 1960--99.From about 1960 the Aral Sea's water level was systematically and drastically reduced because of the diversion of water from the Amu Darya and Syr Darya rivers for purposes of agricultural irrigation. As the Soviet government converted large acreages of pastures or untilled lands in Uzbekistan, Kazakstan, Turkmenistan, and elsewhere into irrigated farmlands by using the waters of the Amu Darya and Syr Darya, the amount of water from these rivers that reached the Aral Sea dropped accordingly. By the 1980s, during the summer months, the two great rivers virtually dried up before they reached the lake. The Aral Sea began to quickly shrink because of the evaporation of its now-unreplenished waters. By the late 1980s, the lake had lost more than half the volume of its water. The salt and mineral content of the lake rose drastically because of this, making the water unfit for drinking purposes and killing off the once-abundant supplies of sturgeon, carp, barbel, roach, and other fishes in the lake. The fishing industry along the Aral Sea was thus virtually destroyed. The ports of Aral in the northeast and Mŭynoq in the south were now many miles from the lake's shore. A partial depopulation of the areas along the lake's former shoreline ensued. The contraction of the Aral Sea also made the local climate noticeably harsher, with more extreme winter and summer temperatures. By 1989 the Aral Sea had receded to form two separate parts, the "Greater Sea" in the south and the "Lesser Sea" in the north, each of which had a salinity almost triple that of the sea in the 1950s. In the late 1990s an island in the Aral Sea, Vozrozhdenya, became the centre of environmental concern. This was of special concern because Vozrozhdenya had been a testing ground for Soviet biological weapons during the Cold War. In addition to testing done there on such agents as tularemia and the bubonic plague, hundreds of tons of live anthrax bacteria were buried on the island in the 1980s. In 1999 still-living anthrax spores were discovered on the site, and scientists feared that when the island was no longer surrounded by water, land vertebrates could carry anthrax to populated areas. Other environmental problems plagued the region as well. By the end of the century the Aral had receded into three separate lakes. The level of the sea had dropped to 125 feet (36 metres) above sea level, and the water volume was reduced by 75 percent of what it had been in 1960. Almost no water from the Amu Darya and the Syr Darya reached the sea, and, unless drastic action were taken, it seemed likely that the Aral Sea could disappear within 20 to 30 years, leaving a large desert in its place. The health costs to people living in the area were beginning to emerge. Hardest hit were the Karakalpaks, who live in the southern portion of the region. Exposed seabeds led to dust storms that blew across the region, carrying a toxic dust contaminated with salt, fertilizer, and pesticides. Health problems occurred at unusually high rates—from throat cancers to anemia and kidney diseases. Infant mortality in the region was among the highest in the world.

Salinity of the Red Sea - why it is so salty
Red Sea is located between the arid areas, desert and semi-desert. The reasons for the active development of reef systems are deeper places and fast water circulation. Water mass of the Red Sea exchanges with the Arabian Sea, the Indian Ocean and Gulf of Aden. These factors reduce the effect of high salinity caused by evaporation of water in the northern part and the relatively hot water in the south of Red sea. The climate is the result of two distinct monsoon seasons: the northeast monsoon and the south-west monsoon. Monsoon winds occur because of varying degrees of warming the surface of the earth and the sea. Very high surface temperature along with salinity makes the Red Sea the warmest salt water in the world (after the Dead Sea). Average water surface temperature in summer is 26 C in the north and 30 in the south. The total average water temperature is 22 C. The sea is known by strong winds and unpredictable currents. The rainfall on the Red Sea and its coasts is extremely small, amounting to 0.06 meters per year. Generally, precipitation falls in the form of short showers often with thunderstorms and occasionally with dust storms. Rare rainfall and a lack of fresh water supply leads to a strong evaporation of 205 cm per year and high salinity of the water. The salinity of the Red Sea, it is one of the saltiest bodies of water in the world because of strong evaporation. The salinity of about 36% in the southern part of the influence of the Gulf of Aden and reaches 41% in the northern part of the influence of the Suez Canal and strong evaporation. The average salinity is 40%. Its salinity is above the world average of around 4%. This is due to the following factors: high evaporation and little precipitation; lack of large rivers flowing; limited connection with the Indian Ocean, the salinity level of which is below.
Halite rafts nucleation at the Dead Sea water surface
Halite precipitation occurs in the Dead Sea as response to its negative water balance. Although the salinity of the lake is the highest at the lake surface due to the evaporation from the lake surface, halite is barely precipitate there. This attribute to warming of the lake surface and mixing processes, both act to reduce salinity and prevent halite nucleation at the lake surface. In this video we present a rare situation of halite rafts nucleation at lake surface during days with calm wave conditions. See more in: Sirota, I., Arnon, A., & Lensky, N. G. (2016).

AMAZING Places BELOW Sea Level
From an airport that operates thousands of feet below sea level, too one of the saltiest places on earth here’s some amazing sights that the ocean could look down on. Taieri Plain Lying just north of the Dunedin International Airport, is New Zealand’s lowest point, two meters below sea level. It’s all a part of the Taieri Plain, a three hundred square kilometer patch of farmland. The land is dominated by farm animals and lovely towns like Mosgiel and Maungatua. Floods in the region happen regularly and can be severe. Lammefjord This agricultural land in Denmark used to be a body of water. But a draining project started in 1873 and it took a really long time to complete. It wasn’t until 1943 that the lowest lying elevations were pumped dry. Now the land is ideal for growing things like carrots and potatoes. At seven meters below sea level it's, along with a polder in the western Netherlands, one of the lowest lying points in all of western Europe. Georgetown The busiest place in Guyana (guy-anna), Georgetown is also the country's capital and is where some 120 thousand people call home. Normally it lies right at sea level, 0, but at high tide it's actually one meter below sea level. It's for this reason that the land is protected by a seawall and authorities decided to install an intricate network of canals to drain the city. Georgetown is hot and humid. There’s no dry season however, with all 12 months experiencing at least 2 average inches of precipitation. New Orleans Until the Louisiana purchase in 1803 Napoleon and the French owned New Orleans. The city was named after a French Regent in 1718. After the U.S. purchased the land New Orleans would become a melting pot of cultures, with American, French, Creole and African people creating a diverse mix of lifestyles. It’s why the city is such a unique, fun place to experience. Parts of the city lie a few meters below sea level. By the late 20th century city officials began to realize that New Orleans could be vulnerable to flooding. Events like Hurricane Betsy in 1965 and a flood in May of 1995 demonstrated as much. The first mandatory evacuation in the city's history occurred in the same year, and was in lieu of Hurricane Katrina. While most residents had left by the time Katrina hit land, more than 1,500 people were lost during the disaster. During the hurricane the cities federal flood protection system failed. 80% of the city would flood as a result. The event is one of the worst civil engineering disasters of all time, and many say the worst since Chernobyl in 1986. Lake Eyre It doesn’t often fill, but when it does, Lake Eyre in central Australia become the largest lake in the country. Even when it's not full, it's home to the country’s lowest point at 49 feet below sea level. The salinity of the lake, which is at ocean levels when full, increases as water evaporates. Saturation occurs and at this poi9nt the lake turn pink. There’s just one more place left to learn about, but first we’d like to thank everyone for watching. We hope you learned something interesting in the last nine minutes and we invite you to subscribe and tune into our next video. Now for one more place, and it’s a city that’s constantly having to hold water at bay, Kristianstad Sweden's lowest point, nearly two and a half meters below sea level can be found in this city. It’s why parts have systems of levees and pumps in place for flood protection. In the recent past they’ve gone to great lengths to protect the environment. They use no oil, coal or natural gas to warm buildings, a remarkable turnaround considering that just two decades ago all of their heating came from fossil fuels.

Osmosis in Potato Strips - Bio Lab
Flipped learning lesson on this osmosis lab HERE: http://sciencesauceonline.com/bio/osmosis-lab/ Follow me on Instagram: https://www.instagram.com/sciencesauce_online/ Twitter: https://twitter.com/science_sauce/ Web: http://sciencesauceonline.com/ Osmosis is a special type of diffusion that applies to water and other solvents. If you take a litre of pure water, and compare it to a litre of sea water, which is very salty, there is less water present in sea water litre because some of that litre is occupied by salt. The saltwater has a lower water potential. If there is a partially permeable membrane, like a cell membrane, separating two different samples of water, there will be a net movement of water from the place with higher water potential to the place with lower water potential. This is the reason plant roots take in water: the rain water the enters the soil has a higher water potential than inside of the roots, so water moves into the roots by osmosis. We can demonstrate this in a lab setting using potatoes. First you’ll need a cork borer to get your potato strips. Push it through the potato, then use the narrower piece to push the strip out. For this experiment we need 18 strips. Once you’ve got as much as you need, tidy them up with a knife to remove the skins. All strips need to be the same length to begin with. He we’re cutting them all down to 6cm. Once they’re ready, get 6 beakers and put 3 tubes in each. This will give you three repeats for each solution. Next thing to do is make your solutions. Put a sheet of paper on the balance, hit “tare” to get starting point of zero, and add the salt until it reads “1g”. Once that’s in the beaker, you need 100 mL of water. Pour into the measuring cylinder keeping your eyes on level with “100mL” until it reaches the line. And then add that to your salt. Here we’ve just made a salt solution of “1 g per 100mL”. In this experiment we need six solutions: 0g per 100ml, which is just pure water, and 1 to 5 g/ 100mL in 1 g increments. Once the solutions are ready, pour them in to immerse the potato strips. Start the timer, and leave them for 20 minutes. After 20 minutes your have to measure all of the strips. Measure them as accurately as possible. To the nearest mm is good for this experiment. As you’re working with the potato strips you probably notice that the once immersed in more concentrated solutions are more soft, which the ones immersed in lower concentrations are much more turgid. Make a quick note of each value you measure as you’re going. To process the data you need a table of results with all concentrations listed, as well as the starting lengths of the strips. These all started at 6.0cm. In the next column put in the values your measured, and then calculate the percentage change for each individual strip. Notice the negative sign on some values, this tells us whether the strips increased or decreased in length. Next you can take an average of changes in length. These are the values that we need to put on a graph. The graph should show the average change in length against the salt concentration. And the results from this experiment show a nice downward curve. The lower salt concentrations result in an increase in length of the potato strip, meaning water has ENTERED the potato strips by osmosis. This means there is a higher water potential inside the solution compared with the potato. We have a hypotonic solution. At higher salt concentrations, however, we have a decrease in potato strip length. This tells us the water potential is higher inside of the potatoes, so water as left the potato strips by osmosis. We can say that the solutions are hypertonic to the potatoes. At the point the graph crosses zero, which is about 1.4 g/100mL salt, the solution is isotonic, meaning the water potential inside potato is equal to the solution, to at that point there is no net movement of water.

Dead Sea, Israel (quadcopter)
The Dead Sea in Israel attracts many people from all over the world. It's the lowest point on the earth (427 meters below sea level) and a natural health spa. The water has the highest concentration of salt in the world, that's why it's called the Dead Sea, as there's no any form of life in the sea due to the salinity. On the other hand, it provides health effects and therapies, as the waters are rich with minerals. It's warm there all year round and the place has become a modern vacation destination and a great combination of calmness, relaxation and treatment.

Human Carbon Emissions Are Dissolving Ocean Floor
It seems humanity isn’t just content to screw up the surface of the planet. We’re gonna do the deep ocean, too. Findings published this week show that all the carbon dioxide piling up in the ocean’s dark depths is causing the seafloor as we know it to dissolve. The results, published this week in the Proceedings of the National Academy of Sciences, are yet another reminder this era of human history will leave a geological mark long after we’re gone. https://earther.gizmodo.com/human-carbon-emissions-are-dissolving-the-ocean-floor-1830178302 http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

All the major groups of marine invertebrates as well as all aquatic vertebrates live in this zone since this is the only area of the ocean where photosynthesis occurs. Temperatures can vary anywhere between 25*C near the equator down to about 5*C near the poles. *The 2nd layer known as the bath-E-al zone, starts where light stops and goes down to the average depth of the ocean floor about 4,000 meters down. Since this area is in complete darkness 24 hours every day no plants live in this zone as well as the zones below. How-ever all the major groups of marine vertebrates such as whales & fish as well as all the major invertebrate groups inhabit this zone. Since light gets absorbed in the layer above, this zone averages temperatures at about 5*C to 4*C all over earth. *The 3rd layer know as the abyssal zone, starts from the average depth of the ocean floor down to about 6,000 meters where most trenches and troughs begin. The only marine vertebrates that inhabit this zone are fish because the massive amount of pressure would pop the lungs of these vertebrates. Despite the pressures all major groups of invertebrate still inhabit the abyssal plains. Average temperatures of this zone vary between 3*C & 2*C. *The 4th layer known as the hadal zone, starts at 6,000 meters where the 14 known troughs and 33 known trenches begin. The Mariana trench bottoms out at about 11,000 meters. With pressures 1,000 times the PSI of the atmosphere you might think that this hostile environment couldn't possibly contain living organisms. How-ever very few fish species as well as all the major known invertebrates groups make their home here.

Using and mixing Instant Ocean salts
If you’ve decided to dive into the world of saltwater aquarium keeping, you’ll want to use a salt mix that is of the highest quality, accurately replicates natural seawater and, more importantly, is consistent. Instant Ocean® Sea Salt, which is universally preferred by public aquariums, offers two types of salt. Knowing which salt to use depends on the environment and the amount of vitamins and trace elements its inhabitants require for optimum growth. For a fish-only environment, with no corals or live rock, Instant Ocean Sea Salt is recommended. But for a more advanced reef environment–– populated with live rock, invertebrates, and soft and hard corals––we recommend Instant Ocean Reef Crystals…because it contains higher levels of vitamins and trace elements, such as strontium and magnesium, as well as extra calcium, that more complex marine life need to grow. Use a container that is clean and devoted only to mixing salt. Since you will be performing regular water changes, make sure it’s big enough to hold the amount of water you’ll be replacing. For a saltwater aquarium, you should replace at least 30% of the water every 30 days, or sooner, depending on your tank’s inhabitants. (Purple cap scene) If using tap water, be sure to use a dechlorinator to completely neutralize any concentrations of chlorine and chloramines. Always add the salt mix to a purified water source, not the other way around. Adding water to the salt mix briefly creates a highly concentrated solution that can lead to precipitation of some ingredients. Use a half a cup of Instant Ocean Sea Salt or Reef Crystals to one U.S. gallon of water to attain specific gravity of one point zero two two (1.022). Depending on the water source, this amount of salt may need to be adjusted. It’s also common practice for saltwater tanks to have a slightly higher salinity to match the specific gravity of natural seawater, which is 1.026 (one point zero two six). To achieve this, just add a bit more salt and, once mixed, use a hydrometer to verify the specific gravity. If it’s too high, simply add more purified water. To properly mix aquarium salt, insert a powerhead into the container to thoroughly dissolve and uniformly mix the salt overnight. This allows the carbon dioxide in the aquarium water to reach equilibrium with the carbon dioxide in the atmosphere, which normalizes pH. It also adds oxygen to the water. Finally, always make sure any unused salt is re-sealed in the container after use to avoid contamination. To learn more, visit www.instantocean.com or our Facebook page.

Kiribati, the sinking Pacific island paradise VIDEO
Please Subscribe, Like & Comment. Thank You. Kiribati, the sinking Pacific island paradise VIDEO SOUTH TARAWA, Kiribati (Reuters) - The ocean laps against a protective seawall outside the maternity ward at Kiribati's Nawerewere Hospital, marshalling itself for another assault with the next king tide. Inside, a basic clinic is crowded with young mothers and newborn babies, the latest additions to a population boom that has risen as relentlessly as the sea in a deeply Christian outpost where family planning is still viewed with skepticism. It is a boom that threatens to overwhelm the tiny atoll of South Tarawa as quickly as the rising seas. Some 50,000 people, about half of Kiribati's total population, are already crammed onto a sand and coral strip measuring 16 sq km (6 sq miles). "Climate change is a definite long-term threat to Kiribati, there's no doubt whatsoever about that," says Simon Donner, a climate scientist at the University of British Columbia who has been visiting South Tarawa since 2005. "But that doesn't mean it's the biggest problem right now ... Any first-time visitor to Tarawa is not struck by the impacts of sea level rise, they're struck by how crowded it is." Low-lying South Pacific island nations such as Kiribati (pronounced Kee-ree-bahs) and Tuvalu, about halfway between northeast Australia and Hawaii, have long been the cause célèbre for climate change and rising sea levels. Straddling the equator and spread over 3.5 million sq km (2 million sq miles) of otherwise empty ocean, Kiribati's 32 atolls and one raised coral island have an average height above sea level of just two meters (6-1/2 feet). Studies show surrounding sea levels rising at about 2.9 mm a year, well above the global average of 1 - 2 mm a year. Kiribati President Anote Tong has grimly predicted his country will likely become uninhabitable in 30-60 years because of inundation and contamination of its fresh water supplies. OVERCROWDING "A MENACE" While climate change poses a serious longer-term threat, many people, including Tong, recognize that breakneck population growth is a more immediate problem. South Tarawa' population density of more than 3,000 per sq km is comparable to Los Angeles or parts of London - without the high rises. The government fears South Tarawa's population could double to more than 100,000 by 2030 unless the birth rate and internal migration slows. Rudimentary huts of little more than timber sleeping platforms and palm thatch roofs line a single dusty road running the length of the atoll. Dotted among them are pig pens, chicken coops, overcrowded grave sites and the blasted relics from one of the bloodiest battles of World War Two. Bwabwa Oten, Kiribati's director of hospital services, says current annual population growth in Kiribati is close to 6 percent, with overcrowding a major contributor to disease and an infant mortality rate among the highest in the region. The church plays an integral role in the South Pacific and efforts to limit birth rates have run into resistance. Large families are also traditional in the region, which has one of the world's highest rates of teen pregnancy. Describing the population surge as "a menace", Tong has called on churches to help curb growth by allowing their members to use birth control. "Religion is incredibly powerful in the Pacific and there is quite an overt suspicion that, when we are talking about family planning, it in fact means family stopping," said Bronwyn Hale of New Zealand-based Family Planning International, which is working to promote sexual and reproductive health in Kiribati. Progress is being made, with clinic visitor numbers up and a growing acceptance of the threat of over-population. "Right now, population is the major issue, the number one issue we should face," said Peter Itibita, a member of the Mormon Church in South Tarawa. Many health problems also stem from a lack of clean water as rising salinity and pollution affect underground water, with diarrhea outbreaks caused by contamination from human and animal waste and other pollutants. Nawerewere Hospital also has problems, with new mothers spilling from overcrowded wards onto verandas and into corridors. "Sometimes with the new babies, we don't have the water to wash them," says Rina Tabi, a maternity ward nurse. Plans are underway for solar-powered energy and desalination plants but the cost of building and maintaining them is a challenge for cash-strapped Kiribati, which relies on aid and royalties from foreign fishing fleets. The complexities of sea level change are becoming more apparent and there is little doubt that nations like Kiribati will be among the most affected. But it is equally clear that vulnerable states like Kiribati are responsible for less than 0.1 percent of global emissions of greenhouse gases from burning fossil fuels.

TDS in drinking water? (Check this out)
Total dissolved solids (TDS) is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form. Generally the operational definition is that the solids must be small enough to survive filtration through a filter with two-micrometer (nominal size, or smaller) pores. Total dissolved solids are normally discussed only for freshwater systems, as salinity includes some of the ions constituting the definition of TDS. The principal application of TDS is in the study of water quality for streams, rivers and lakes, although TDS is not generally considered a primary pollutant (e.g. it is not deemed to be associated with health effects) it is used as an indication of aesthetic characteristics of drinking water and as an aggregate indicator of the presence of a broad array of chemical contaminants.

DermaSel Dead Sea Salts
Derma Sel Dead Sea Salts The salty water of the Dead Sea The mineral content of the Dead Sea is significantly different from that of ocean water, consisting of approximately 53% magnesium chloride, 37% potassium chloride and 8% sodium chloride (salt) with the remainder comprised of various trace elements. Comparison between the chemical composition of the Dead Sea to other lakes and oceans show that the salt concentration in the Dead Sea is 31.5%. Due to its unusually high concentration of salt, anyone can easily float in the Dead Sea because of natural buoyancy as a result of the higher density of the water. The sea is called "dead" because its high salinity means no fish or macroscopic aquatic organisms can live in it, though minuscule quantities of bacteria and microbial fungi are present. The minerals in the Dead Sea Salt The concentration of sulfate, SO42-, ions is very low, and the bromide ion concentration is the highest of all waters on Earth. Chlorides neutralize most of the calcium ions in the Dead Sea and its surroundings. While in other seas sodium chloride is 97% of the salts, in the Dead Sea the quantity of NaCl is only 12-18%. In the following the four most important minerals are characterized: Magnesium Magnesium concentrations found in the Dead Sea are fifteen times higher than salts in other seas and are essential for cell metabolism. For instance, a significant deficit in Magnesium has been discovered in skin scales and serum of patients with psoriasis. Magnesium supposedly affects the ripening of skin cells of psoriasis patients. Moreover, in cases of bronchi, Magnesium works as anti-allergic agent. Potassium Potassium is a basic element of the human body. It regulates the water balance of the skin, strengthens its defence mechanism and is anti-inflammatory. Bromine Bromine is necessary for the production of the cyclic hormone AMP which regulates the regeneration of the skin and ensures the normalization of the skin's peeling process. It has an extreme soothing effect on the skin and the entire organism. Calcium Calcium has an anti-allergic, itch-relieving effect and relieves the sensitive skin. It prevents infections and supports the skin balance. This unique mineral combination from the Dead Sea is present in all DermaSel Products.

People love to play in the waves, surf the waves, and the sound of the waves crashing on the beach. What causes ocean waves? Ocean waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water. This causes waves to form. What is a wave? In science, a wave is defined as a transfer of energy. Ocean waves are called mechanical waves because they travel through a medium. The medium in this case is water. The water doesn't actually travel with the wave, but only moves up and down. It's the energy that travels with the wave. What are swells? Swells are rolling waves that travel long distances through the ocean. They are not generated by the local wind, but by distant storms. Swells are typically smooth waves, not choppy like wind waves. A swell is measured from the crest (top) to the trough (bottom). Ocean Currents An ocean current is a continuous flow of water in the ocean. Some currents are surface currents while other currents are much deeper flowing hundreds of feet below the surface of the water. What causes ocean currents? Surface currents are usually caused by the wind. As the wind changes, the current may change as well. Currents are also influenced by the rotation of the Earth called the Coriolis effect. This causes currents to flow clockwise in the northern hemisphere and counter clockwise in the southern hemisphere. Deep ocean currents are caused by a number of things including changes in the temperature, salinity (how salty the water is), and density of the water. One other factor impacting ocean currents is the gravitational pull of the Moon and the Sun. Do currents impact the climate? Ocean currents can have a significant impact on climate. In some areas warm water is moved from the equator to a colder region causing the region to be warmer. One example of this is the Gulfstream current. It pulls warm water from the equator to the coast of Western Europe. As a result, areas such as the United Kingdom are typically much warmer than areas at the same northern latitude in North America. Interesting Facts about Ocean Waves and Currents ► The tallest wave ever measured was 1719 feet at Lituya Bay, Alaska. ► The tallest wave recorded in the open ocean was 95 feet during a storm near Scotland. ► Surface currents are important to ships as they can make it easy or difficult to travel depending on the direction of the current. ► Some marine animals take advantage of currents to migrate thousands of miles to and from breeding grounds. ► Ben Franklin published a map of the Gulf Stream in 1769. =============== And don't forget to put Likes on FB! ► http://bit.ly/yourrelaxfb Follow us on Twitter! ► https://twitter.com/YouRRelaxMusic Subscribe to us in the Telegram ► spiritualsense =============== © This music is reserved by all rights presented by the law of united states of America. ©
How the Salton Sea went from resorts to a 'public health disaster'
How the Salton Sea went from resorts to a 'public health disaster': http://www.dailymail.co.uk/news/article-5839677/A-ghost-town-making-Salton-Sea-went-busy-resorts-public-health-disaster.html. Thanks for watching, subscribe for more videos: https://www.youtube.com/channel/UCqi7z1Xa_8CBhQStlApH8ww?sub_confirmation=1 With sandy beaches and warm water year-round, Salton Sea in California was the perfect family getaway of the 1950s and 60s. It attracted Hollywood’s elite - Rock Hudson water-skied there, Frank Sinatra and Jerry Lewis visited their friend Guy Lombardo’s yacht which was moored there. The Beach Boys were members of the North Shore yacht club, Sonny Bono was a visitor and President Dwight Eisenhower golfed there.Business was booming - hotels, motels, casinos and yacht clubs popped up along the lake’s 116-mile shoreline helping to create enclaves including Bombay Beach and Salton City. Residents and developers quickly reaped the benefits of the influx.Back then it was called the ‘miracle in the desert’. Today, it is described as an ‘ecological nightmare and disaster’ - a ghost town in the making.The Salton Sea was accidentally created when in 1905 the Colorado River swelled, breached its levees and flooded into the Salton Sink desert valley. For two years the water flowed, creating the Salton Sea – a 15-mile by 35-mile freshwater lake 45miles outside of Palm Springs. By the 1970s it was in decline due to there being almost no rainfall, no way for the lake to drain and runoff water contaminated with pesticides from nearby farms flowed into it. Salt levels increased making it saltier than the Pacific Ocean, depleting oxygen levels in the water. Thousands of fish died annually and washed onto the shore where they shriveled up and decayed in the extreme heat.Where holidaymakers once sunbathed, the sand is littered with sun-bleached fish carcasses. On hot summer days when the temperature can reach up to 120F (48.8C), a pungent sulphur odor hangs in the air that can be smelled 150 miles away in Los Angeles. In short, the Salton Sea smells of rotten eggs.The once-bustling hotels are derelict, broken wooden frames of buildings stand in some spots as other structures are badly decaying with graffiti spray painted over the boarded-up windows and doors.But it isn’t just the smell and the ecological impact that people are concerned about. The most pressing issue for residents near the Salton Sea is the continued threat of toxic dust that sweeps up from the dry lakebed containing harmful pesticides, heavy metals and powdery-fine particles that are linked to asthma, respiratory diseases and even cancer.   One in five children in Imperial County suffer from asthma and have lung related illnesses compared with a national average of 1 in 12, according to the latest government data. Dr. Tim Krantz, the recognized authority on the geography of the Salton Sea, said it is a ‘public health disaster’ in the making. Krantz, who served as the Salton Sea Database Program Director, said: ‘Our real concern changed from the ecology and the loss of that which is important, but our real focus became what’s going to happen to these toxic dry lakebed sediments once they are exposed to the desert winds?‘It will be an air quality disaster unparalleled in the world.

Mount Nebo and Dead Sea; Jordan
Mount Nebo is an elevated ridge in Jordan, approximately 810 metres above sea level, mentioned in the Hebrew Bible as the place where Moses was granted a view of the Promised Land. The view from the summit provides a panorama of the Holy Land and, to the north, a more limited one of the valley of the River Jordan. The West Bank city of Jericho is usually visible from the summit, as is Jerusalem on a very clear day. According to the final chapter of the Book of Deuteronomy, Moses ascended Mount Nebo to view the Land of Canaan, which God had said he would not enter, and to die there; he was buried in an unknown valley location in Moab On the highest point of the mountain, the remains of a Byzantine church and monastery were discovered in 1933. The church was first constructed in the second half of the 4th century to commemorate the place of Moses' death. The church design follows a typical basilica pattern. It was enlarged in the late fifth century A.D. and rebuilt in A.D. 597. Six tombs have been found hollowed from the natural rock beneath the mosaic-covered floor of the church. In the modern chapel presbytery, built to protect the site and provide worship space, remnants of mosaic floors from different periods can be seen. The earliest of these is a panel with a braided cross presently placed on the east end of the south wall. A serpentine cross sculpture (the Brazen Serpent Monument) atop Mount Nebo was created by Italian artist Giovanni Fantoni. The Dead Sea is a salt lake bordered by Jordan to the east and Israel and Palestine to the west. Its surface and shores are 430.5 metres below sea level, Earth's lowest elevation on land. The Dead Sea is 304 m deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2%, (in 2011), it is 9.6 times as salty as the ocean and one of the world's saltiest bodies of water. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea is 50 kilometres long and 15 kilometres wide at its widest point. The Dead Sea has attracted visitors from around the Mediterranean basin for thousands of years. It was one of the world's first health resorts. The Dead Seawater has a density of 1.24 kg/litre, which makes swimming similar to floating.

Sakhalin and Kamchatka from 22 Dec 2017 to 26 Dec 2017 +11
Sakhalin island and Kamchatka peninsula as seen from space. To the east of Kamchatka is the Bering sea with the Aleutian chain leading towards Alaska. To the west of Kamchatka is the Sea of Okhotsk. Pay special attention to sea ice moving slowly in that area especially during breakup time from April to June. The Amur river is introducing vast amounts of fresh water into the sea, lowering the salinity of the Sea of Okhotsk, therefore raising the freezing temperature. The orientation of the movie is tilted to the right by just a few degrees. Geographic North is thus almost at the leftmost edge of this movie.
