Fresh Water Meets Sea Water – Boundary Explained
This is the Fraser River Delta just in front of Vancouver BC Canada, this is where sea water meets fresh water. The river water from Fraser River, flowing into the ocean water of the Strait of Georgia. Modern Science has discovered that in the places where two different bodies meet, there is a barrier between them. This barrier creates a noticeable line, as each water body has its own temperature, salinity, and density. If you go on google earth and look up Fraser River or Sea Island which is an airport right at the water edge, you will see this boundary line stretching for miles.

The evaporating Mediterranean Sea | BBC
Six million years ago the continents of Africa and Europe collided to close the Strait of Gibralter. Starved of water, the Mediterranean Sea evaporated to form a vast desert. The legacy of this vanished ocean? A million years' worth of salt deposited in mines half a kilimetre beneath the island of Sicily.

Atlantic and Pacific oceans joining at a point in mid ocean but do not mix each other | Unbelievable
On the temperature, salinity, and density differences between the Atlantic and Pacific oceans in the upper kilometre. Abstract The surface of the Pacific Ocean stands about 40 cm higher than the Atlantic Ocean with respect to the 1000-decibar surface, and the North Atlantic and North Pacific stand respectively about 14 and 17 cm higher than the South Atlantic and Pacific. The North Atlantic is warmest and saltiest, the South Atlantic is coldest and densest, and the North Pacific is least dense and least salty. The extreme values in temperature and salinity of the North Atlantic are probably related to the formation of the deep water there, which carries away from the upper layer the cold water of relatively low salinity. If this water spreads into the South Atlantic at depth and is replaced with warm saline surface water from the South Atlantic via the South Equatorial Current and the Gulf Stream, then the South Atlantic should be substantially cooler and less salty. The difference in density and sea level of the Atlantic and Pacific oceans may stem from the difference in latitude of the southern tips of America, Africa, and Australia, and the constriction of the west wind drift at Drake Strait. Only the densest surface waters of the Pacific pass through to the Atlantic, while lighter waters from lower latitudes of the South Atlantic pass eastward south of Africa. Further, the constriction of the flow by Drake Strait may result in a higher sea level on the Pacific side through the effect of Windstau (Montgomery, 1938). The density difference between the southern and northern oceans may be partly a consequence of the west wind drift around Antarctica. This is the greatest current of all oceans. Its flow is approximately geostrophically balanced and the surface slopes down to the south. The northern west wind drifts are not so strong, are at lower latitudes, and the high latitude flow is westward with slope upward to the north. These differences are not confined to the upper thousand metres. The average density difference between the Atlantic and the Pacific from the surface to the bottom is about 17 × 10−5 g/cm3. Referred to some deep surface such as 4000 decibars, the Pacific stands about 68 cm higher than the Atlantic.

Footage: Algae color ‘China’s Dead Sea’ in red and green
A salt lake in the city of Yuncheng, north China’s Shanxi Province, has proven that Mother Nature is an unmatched colorist.   The waters of the salt lake seem to have been dyed in red on one side of the lake, while staying green on the other side. Fittingly enough, an avenue rising above the lake played the demarcation line, separating the two colors in such precision that prompted visitors to snap pictures of this scientifically-explained natural miracle.   The distinct pinkish red color was caused by the proliferation of a certain type of algae Dunaliella salina, it has been reported.   Covering an area of 120 square kilometers, the salt lake, which stretches 30 kilometers in length, is the largest in Shanxi Province and the world’s third largest sodium sulphate inland lake. Due to its high salinity, the lake has been dubbed as “China’s Dead Sea” and offers a safe destination for swimmers who can’t stay afloat.

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.
The Dead Sea is drying up at an alarming rate
The Dead Sea has already lost more than one third of its surface area over the years. The water level is currently dropping by over 1 meter every year and its shoreline is expected to drop from 411 meters to 430 meters below sea level by 2020, according to the environmentalist group EcoPeace Middle East. Traditionally, the Jordan River is the Dead Sea’s inflow source. However, 50 years ago it was diverted to supply cities, reducing the water inflow level to the Dead Sea to just 5% of its original volume. The hot and dry climate of the region makes it difficult for the Dead Sea to restore itself. That added to the rapid loss of water has resulted in the increased salinity of the lake. The group also points out that the Dead Sea is threatened by cosmetic companies that extract mineral water from the region to make beauty products. Hotels and attractions built along the shoreline also release untreated sewage into the Dead Sea. Even though the Dead Sea does not have any wildlife in itself, the region around it is known for supporting several endangered species such as ibexes, leopards and the indigenous Dead Sea Sparrow. ----------------------------------------­­---------------------------------------­-­---------------- Next Animation Studio’s News Direct service provides daily, high-quality, informative 3D news animations that fill in for missing footage and help viewers understand breaking news stories or in-depth features on science, technology, and health.

Farming With Salty Water Is Possible
One of the many adverse effects of global climate change is the rise of sea levels, which scientists say can increase the salinity level of fresh water reserves. As saline water cannot be used for irrigation, farm fields close to the seashore are lost to agriculture. But a farm in Netherlands has managed to grow healthy and tasty vegetables in soil irrigated with salt water. VOA’s George Putic reports.

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.

NASA | The Ocean: A Driving Force for Weather and Climate
The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable. This animation helps to convey the importance of Earth's oceanic processes as one component of Earth's interrelated systems. This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites to measure physical oceanography parameters such as ocean currents, ocean winds, sea surface height and sea surface temperature. These measurements, in combination with atmospheric measurements such as surface air temperature, precipitation and clouds can help scientists understand the ocean's impact on weather and climate and what this means for life here on Earth. NASA satellites and their unique view from space are helping to unveil the vast... and largely unexplored.... OCEAN. NASA Earth Observing System Data and Information Systems (EOSDIS) EOSDIS is a distributed system of twelve data centers and science investigator processing systems. EOSDIS processes, archives, and distributes data from Earth observing satellites, field campaigns, airborne sensors, and related Earth science programs. These data enable the study of Earth from space to advance scientific understanding.

Why is Ocean water Salty? | #aumsum #kids #ocean #water #salty
Several natural processes make ocean water salty. For example, when it rains, the water droplets react with carbon dioxide in the atmosphere and form carbonic acid, making rainwater slightly acidic. This acidic rainwater reacts with minerals present in the rocks and forms new minerals and salts. This acidic rainwater reacts with minerals present in the rocks and form new minerals and salts. These minerals and salts are then carried by flowing water to the oceans, thus making the ocean water salty. In addition to this, along the mid-ocean ridges, magma rises close to the oceanic crust. Here, when the salty ocean water seeps into the earth's crust, it gets hot due to magma. This hot water dissolves more minerals present in the crust and carries them to the oceans through fissures called hydrothermal vents, thus making the ocean water salty.

OG-30 | Salinity of Ocean & it's deposit |सागरीय लवणता और निक्षेप। For UPSC and state PSc
Is video me hum mahasagariya jal ki salinity ke baare me padhenge . Topic Covered 1- Salinity 2- Cause of Salinity of water 3- Factors effecting Salinity of Ocean Water 4- Horizontal distribution of Salinity of Ocean 5 - Vertical distribution of Salinity of Ocean Factors Affecting Ocean Salinity The salinity of water in the surface layer of oceans depend mainly on evaporation and precipitation. Surface salinity is greatly influenced in coastal regions by the fresh water flow from rivers, and in polar regions by the processes of freezing and thawing of ice. Wind, also influences salinity of an area by transferring water to other areas. The ocean currents contribute to the salinity variations. Salinity, temperature and density of water are interrelated. Hence, any change in the temperature or density influences the salinity of an area. Horizontal distribution of salinity To make life easier, I will remove the symbol o/oo and place only number The salinity for normal open ocean ranges between 33 and 37. High salinity regions In the land locked Red Sea (don’t confuse this to Dead Sea which has much greater salinity), it is as high as 41. In hot and dry regions, where evaporation is high, the salinity sometimes reaches to 70. Comparatively Low salinity regions In the estuaries (enclosed mouth of a river where fresh and saline water get mixed) and the Arctic, the salinity fluctuates from 0 – 35, seasonally (fresh water coming from ice caps). Pacific The salinity variation in the Pacific Ocean is mainly due to its shape and larger areal extent. Atlantic The average salinity of the Atlantic Ocean is around 36-37. The equatorial region of the Atlantic Ocean has a salinity of about 35. Near the equator, there is heavy rainfall, high relative humidity, cloudiness and calm air of the doldrums. The polar areas experience very little evaporation and receive large amounts of fresh water from the melting of ice. This leads to low levels of salinity, ranging between 20 and 32. Maximum salinity (37) is observed between 20° N and 30° N and 20° W – 60° W. It gradually decreases towards the north.distribution of ocean salinity Indian Ocean The average salinity of the Indian Ocean is 35. The low salinity trend is observed in the Bay of Bengal due to influx of river water by the river Ganga. On the contrary, the Arabian Sea shows higher salinity due to high evaporation and low influx of fresh water. Marginal seas The North Sea, in spite of its location in higher latitudes, records higher salinity due to more saline water brought by the North Atlantic Drift. Baltic Sea records low salinity due to influx of river waters in large quantity. The Mediterranean Sea records higher salinity due to high evaporation. Salinity is, however, very low in Black Sea due to enormous fresh water influx by rivers. Inland seas and lakes The salinity of the inland Seas and lakes is very high because of the regular supply of salt by ‘ the rivers falling into them. Their water becomes progressively more saline due to evaporation. For instance, the salinity of the Great Salt Lake , (Utah, USA), the Dead Sea and the Lake Van in Turkey is 220, 240 and 330 respectively. The oceans and salt lakes are becoming more salty as time goes on because the rivers dump more salt into them, while fresh water is lost due to evaporation. Cold and warm water mixing zones Salinity decreases from 35 – 31 on the western parts of the northern hemisphere because of the influx of melted water from the Arctic region. surface salinity of world's oceans Sub-Surface Salinity With depth, the salinity also varies, but this variation again is subject to latitudinal difference. The decrease is also influenced by cold and warm currents. In high latitudes, salinity increases with depth. In the middle latitudes, it increases up to 35 metres and then it decreases. At the equator, surface salinity is lower. Vertical Distribution of Salinity Salinity changes with depth, but the way it changes depends upon the location of the sea. Salinity at the surface increases by the loss of water to ice or evaporation, or decreased by the input of fresh waters, such as from the rivers. Salinity at depth is very much fixed, because there is no way that water is ‘lost’, or the salt is ‘added.’ There is a marked difference in the salinity between the surface zones and the deep zones of the oceans. The lower salinity water rests above the higher salinity dense water. Salinity, generally, increases with depth and there is a distinct zone called the halocline (compare this with thermocline), where salinity increases sharply. Other factors being constant, increasing salinity of seawater causes its density to increase. High salinity seawater, generally, sinks below the lower salinity water. This leads to stratification by salinity.

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.

10 Spectacular Underwater Rivers & Lakes!
Divers have discovered a whole new world beneath ours filled with underwater lakes, rivers, waterfalls, ponds and even, an ocean. 10 Spectacular Underwater Rivers & Lakes! SUBSCRIBE for the latest videos: https://goo.gl/7xzjzR Don't forget to CHECK OUT our latest upload: https://goo.gl/LUB8Xw The Monterey Submarine Canyon Due to highly lethal concentrations of methane and hydrogen sulfide found within, the newly formed water cannot mix with the surrounding sea. Thus, the potency of the water can be deadly to any diver or animal who swim into it. For this reason, new forms of bacteria and sea creatures have evolved in order to survive this unusual environment. It lies two miles beneath the ocean’s surface in one of the biggest underwater canyons on the west coast— the Monterey Submarine Canyon. The Underwater Torrent of the Black Sea Up to thirty-five meters deep and one kilometer wide, this churning channel snakes sneakily along the belly of the Black Sea. Due to its extremely high level of salinity, the water found here is physically prevented from mixing with the lesser salty waters of the surrounding sea. Scientists from the University of Leeds began tracking the river's progress with an underwater robot until the machine vanished into the cavernous abyss at around 60 kilometers deep. The Hazma River The Amazon river is one of the world’s most diverse passages of water in the world and by far holds the greatest total flow of any river— surpassing the Nile, Mississippi, and the Yangtze combined. To further glorify this rich, natural wonder, there is another spectacular body of water located 4,000 kilometers below its belly. The Hazma river is an underground river named after its discoverer, geophysicist Valiya Hamza, upon its unearthing in the 1980s. What the Amazon beats the latter in length, the Hazma river surpasses with an astonishing 200 kilometers wide at its narrowest point and 400 kilometers wide as its girth. The Cenote Angelita Cenote Angelita, translating to “little angel,” is a natural sinkhole which formed when rocks of limestone in the seabed collapsed to expose groundwater beneath. Famously linked with the Yucatan Peninsula in Mexico, cenotes were often used as sacrificial sites for ancient Mayan practice and ritual. What renders the Cenote Angelita most remarkable today, however, is the saltwater river found cascading along the bottom. The Denmark Straight Cataract This underwater waterfall rivals even the “world’s highest waterfall” when typed into Google’s search engine. To curb the curiosity of which is the highest, look no further than Angel Falls, in Venezuela’s Canaima National park. At a striking 979 meters, this wondrous wonderwork is so tall it dissipates long before hitting its highly anticipated destination down below. The Denmark Straight Cataract is an astonishing 3500 meters tall and is nestled nicely under the Atlantic Ocean between Greenland and Iceland. The Unnamed Lake of Antarctica Along Antarctica's icy exterior exists the largest subglacial lake, Lake Vostok, and as it's submerged under 3.7 kilometers of ice, scientists have yet to uncover the mysteries that lie within these unknown waters. The second largest subglacial lake and ecological epicenter is another fully submerged spectacle spanning Antarctica’s crystal tundra. With a measurement of 100 kilometers long and 10 kilometers wide, researchers associate the lake's shape with that of a ribbon. The Hot Tub of DespairThis brine pool is set 1,000 meters below the water’s surface in the Gulf of Mexico. According to science, the brine pool was formed over a million years ago after the great gulf evaporated. Researchers determine that as heaps of salt were left behind, the brine submerged and then formed an underwater pool with the resurgence of new water. Hot Tub of Despair is so toxic that its lack of oxygen and abundance of methane would devastate any marine life who tried to venture near. The Mauritius Waterfall Situated off the coast of an island called the Republic of Mauritius, 2,000 miles from Africa’s southeastern coast. The secret behind the illusion is due to sand and silt deposits which flow through the area and enhance the color of the water, to reveal a fluctuating cascade of silk transcending to who knows where. An Ocean Inside the Earth When scientists speculated that earth's water was formed by the earth itself, it's due to evidence of an ocean under our ocean. Findings have uncovered a remarkable body of water located 660 kilometers within the earth's crust. The large reservoir of water sits beneath eastern Asia and is reported to contain more water than three times the amount of all the world's oceans combined. Located within a massive mantle known as the transition zone, this region of water exists in a mineral known as ringwoodite.

The Black Sea
The Black Sea is bounded by Europe, Anatolia and the Caucasus and is ultimately connected to the Atlantic Ocean via the Mediterranean and the Aegean seas and various straits. The Bosphorus strait connects it to the Sea of Marmara, and the strait of the Dardanelles connects that sea to the Aegean Sea region of the Mediterranean. These waters separate eastern Europe and western Asia. The Black Sea is also connected to the Sea of Azov by the Strait of Kerch. The Black Sea has an area of 436,400 km² (168,500 sq mi) (not including the Sea of Azov),[1] a maximum depth of 2,212 m (7,257 ft),[2] and a volume of 547,000 km3 (131,200 cu mi).[3] The Black Sea forms in an east-west trending elliptical depression which lies between Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine.[4] It is constrained by the Pontic Mountains to the south, the Caucasus Mountains to the east and features a wide shelf to the northwest. The longest east-west extent is about 1,175 km. Important cities along the coast include Batumi, Burgas, Constanța, Giresun, Hopa, Istanbul, Kerch, Kherson, Mangalia, Năvodari, Novorossiysk, Odessa, Ordu, Poti, Rize, Samsun, Sevastopol, Sochi, Sukhumi, Trabzon, Varna, Yalta and Zonguldak. The Black Sea has a positive water balance; that is, a net outflow of water 300 km3 per year through the Bosphorus and the Dardanelles into the Aegean Sea. Mediterranean water flows into the Black Sea as part of a two-way hydrological exchange. The Black Sea outflow is cooler and less saline, and floats over the warm, more saline Mediterranean inflow -- as a result of differences in density caused by differences in salinity -- leading to a significant anoxic layer well below the surface waters. The Black Sea also receives river water from large Eurasian fluvial systems to the north of the Sea, of which the Don, Dnieper and Danube are the most significant. In the past, the water level has varied significantly. Due to these variations in the water level in the basin the surrounding shelf and associated aprons have sometimes been land. At certain critical water levels it is possible for connections with surrounding water bodies to become established. It is through the most active of these connective routes, the Turkish Straits, that the Black Sea joins the world ocean. When this hydrological link is not present, the Black Sea is a lake, operating independent of the global ocean system. Currently the Black Sea water level is relatively high, thus water is being exchanged with the Mediterranean. The Turkish Straits connect the Black and Aegean Seas and comprise the Bosphorus, the Sea of Marmara and the Dardanelles. Text Source: www.wikipedia.org

Seawater Chemistry - Salinity portion
seawater chemistry pre-lab on salinity
Views: 4033 Keith Meldahl
In oceanography, a halocline (from Greek hals, halo- ‘salt’ and klinein ‘to slope’) is a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water. Because salinity (in concert with temperature) affects the density of seawater, it can play a role in its vertical stratification. Increasing salinity by one kg/m3 results in an increase of seawater density of around 0.7 kg/m3. In the midlatitudes, an excess of evaporation over precipitation leads to surface waters being saltier than deep waters. In such regions, the vertical stratification is due to surface waters being warmer than deep waters and the halocline is destabilizing. Such regions may be prone to salt fingering, a process which results in the preferential mixing of salinity. In certain high latitude regions (such as the Arctic Ocean, Bering Sea, and the Southern Ocean) the surface waters are actually colder than the deep waters and the halocline is responsible for maintaining water column stability- isolating the surface waters from the deep waters. In these regions, the halocline is important in allowing for the formation of sea ice, and limiting the escape of carbon dioxide to the atmosphere. Haloclines are also found in fjords, and poorly mixed estuaries where fresh water is deposited at the ocean surface.

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.

Why is the Sea Water Salty?
If you’ve ever taken a gulp of #SeaWater, either accidentally or in a moment of insanity, then you undoubtedly noticed that seawater is actually very salty. If you haven’t tasted it yet, why not give it a try? We do have plenty of oceans around the world! Contrary to popular belief, freshwater, which is the water we drink, also contains some amount of salt. However, because the concentration of salt is much less than seawater, this salinity isn’t apparent in the taste of the water. There are 2 theories attributed to the #SalinityOfSeawater. One is that when rainwater seeps through large rocks, it mixes with some of the minerals from the rocks, a process that is called weathering. This water, which has taken in some of the salty substances of the rocks, then flows through rivers, making the water in the river slightly salty too. That being said, you won’t find the river water salty, as the concentration of salt in that water is also quite low. The water from all rivers is deposited in the seas and along with it, the salt also gets deposited, making the seawater salty. This exact same process has been going on for millions of years, which has made the salinity of seawater become apparent to our senses. The other reason that is commonly attributed to the salinity of seawater was discovered a number of years ago. There are some areas on the ocean floor where seawater seeps into the oceanic crust, becomes hotter, dissolves minerals from the crust, and then flows back to the ocean. Again, this process takes a long, long time, but it can definitely contribute to salinity. Furthermore, it has been found that underwater volcanic eruptions also impart salinity to seawater. As you can see, there are plenty of popular explanations, but the bottom line is this – don’t take a gulp when you’re thirsty, because it will only make things worse!

The Dead Sea, also known as the Salt Sea, salt lake bordering Jordan to the east 7 Israel With 33.7% salinity, the Dead Sea is one of the world’s saltiest bodies of water The Dead Sea’s unusually high salt concentration means that people can easily float in the Dead Sea due to natural buoyancy The Dead Sea is roughly 8.6 times saltier than the ocean. This salinity makes for a harsh environment in which animals cannot flourish. The high salinity prevents macroscopic aquatic organisms such as fish and aquatic plants from living in it -~-~~-~~~-~~-~- Please watch: "ambedkar park lucknow night beauty, 7 wonder of lucknow, UP" https://www.youtube.com/watch?v=U_tjzk2gKI8 -~-~~-~~~-~~-~-

What is HYDROTHERMAL VENT? What does HYDROTHERMAL VENT mean? HYDROTHERMAL VENT meaning - HYDROTHERMAL VENT definition - HYDROTHERMAL VENT explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs, fumaroles and geysers. Under the sea, hydrothermal vents may form features called black smokers. Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are believed to exist on Jupiter's moon Europa, and Saturn's moon Enceladus, and it is speculated that ancient hydrothermal vents once existed on Mars. Hydrothermal vents in the deep ocean typically form along the mid-ocean ridges, such as the East Pacific Rise and the Mid-Atlantic Ridge. These are locations where two tectonic plates are diverging and new crust is being formed. The water that issues from seafloor hydrothermal vents consists mostly of sea water drawn into the hydrothermal system close to the volcanic edifice through faults and porous sediments or volcanic strata, plus some magmatic water released by the upwelling magma. In terrestrial hydrothermal systems, the majority of water circulated within the fumarole and geyser systems is meteoric water plus ground water that has percolated down into the thermal system from the surface, but it also commonly contains some portion of metamorphic water, magmatic water, and sedimentary formational brine that is released by the magma. The proportion of each varies from location to location. In contrast to the approximately 2 °C ambient water temperature at these depths, water emerges from these vents at temperatures ranging from 60 to as high as 464 °C. Due to the high hydrostatic pressure at these depths, water may exist in either its liquid form or as a supercritical fluid at such temperatures. The critical point of (pure) water is 375 °C at a pressure of 218 atmospheres. However, introducing salinity into the fluid raises the critical point to higher temperatures and pressures. The critical point of seawater (3.2 wt. % NaCl) is 407 °C and 298.5 bars, corresponding to a depth of ~2960 m below sea level. Accordingly, if a hydrothermal fluid with a salinity of 3.2 wt. % NaCl vents above 407 °C and 298.5 bars, it is supercritical. Furthermore, the salinity of vent fluids have been shown to vary widely due to phase separation in the crust. The critical point for lower salinity fluids is at lower temperature and pressure conditions than that for seawater, but higher than that for pure water. For example, a vent fluid with a 2.24 wt. % NaCl salinity has the critical point at 400 °C and 280.5 bars. Thus, water emerging from the hottest parts of some hydrothermal vents can be a supercritical fluid, possessing physical properties between those of a gas and those of a liquid. Examples of supercritical venting are found at several sites. Sister Peak (Comfortless Cove Hydrothermal Field, 4°48'S 12°22'W, elevation -2996 m) vents low salinity phase-separated, vapor-type fluids. Sustained venting was not found to be supercritical but a brief injection of 464 °C was well above supercritical conditions. A nearby site, Turtle Pits, was found to vent low salinity fluid at 407 °C, which is above the critical point of the fluid at that salinity. A vent site in the Cayman Trough named Beebe, which is the world's deepest known hydrothermal site at ~5000 m below sea level, has shown sustained supercritical venting at 401 °C and 2.3 wt% NaCl. Although supercritical conditions have been observed at several sites, it is not yet known what significance, if any, supercritical venting has in terms of hydrothermal circulation, mineral deposit formation, geochemical fluxes or biological activity.

Black Sea Sunrise 🏖
The Black Sea is the stretch of water from the geomorphological basin called Pontic, one of the basins of the Tethysian tectonic complex, itself a part of the Alpine-Himalayan orogenesis, which includes the mountains that bordering it in the north (in the Crimea) to the northeast (Caucasus ) and south (pontic chains). It is located between Europe and Asia, with Russia, Ukraine, Romania, Bulgaria, Turkey and Georgia riparian. The Kerch Strait is linked to the Sea of ​​Azov, through the Bosphorus of the Marmara Sea, and across the Dardanelles to the Aegean Sea and therefore to the Mediterranean Sea. The Black Sea is, from a hydrological point of view, a remnant of the Sarmatian Sea and presents a number of unique aspects in the world: saltwater (average 16-18 grams of salt per liter compared to 34-37 in other seas and oceans) stratification between oxygen and deeper anoxic waters (phenomenon called euxinism), limanes to river mouths, flora and fauna with many species-relics. In the Romanian seaside area salinity decreases even more, usually between 7 and 12 per thousand. The Black Sea stretches over an area of ​​423,488 km². The deepest point is 2211 m below sea level near Yalta. Mares are generally of small amplitude (about 12 cm).
