Salinity of Ocean and Seas | Oceans | Geography
According to Wust (1935) the average annual rate of evaporation in the Atlantic Ocean is 94 cm to the north of 40 0 N, 149 cm at 20 0 N and 105 cm near the equator (say thermal equator which is at 5 0 N). Salinity is 34.68 0 / 00 at 5 0 N and more than 37 0 / 00 at 20°N. Evaporation in the southern Atlantic Ocean is 143 cm (per year) at 10 0 S and only 43cm at 5 0 S.. In general subtropical ...
What Species Live In Hypersaline Waters?

Why are hypersaline bodies of water so valuable?
The hypersaline bodies of water have great buoyancy as a result of high salinity levels.
How does salinity affect agriculture?
High water salinity negatively impacts agricultural production in cases where water is used for irrigation. High salt concentrations in soil water cause water to flow from the roots of the plants back to the ground, causing dehydration to the plants. Some salts are also poisonous to plants. In places where people consume water with high salinity ...
Why is water hypersaline?
A hypersaline body of water contains higher saline levels than that of oceans. The salinity is caused by the concentration of sodium chloride or other salts. These bodies of water lack outputs, meaning that they lose water only through evaporation, a process which leaves mineral salts behind.
How much salinity does the ocean have?
Oceans have a 3.5% salinity which is modest compared to some of the world’s saline bodies of water. Sea water is home to numerous chemicals which render it salty. These chemicals originate from rocks and soil which dissolve in the rivers feeding the oceans.
What is the salinity of Lake Vanda?
Lake Vanda, also located in Antarctica has a salinity of 35%. Other saline bodies of water include the Dead Sea, shared between Israel, Jordan and Palestine; Great Salt Lake, Mono Lake, and Salton Sea in the US, and Europe’s Baltic Sea.
What is the Dead Sea known for?
The Middle East is home to the Dead Sea, a famous lake named for the absence of lifeforms. Only bacteria thrive in the lake, and its mud, which contains high concentrations of minerals, is popular for cosmetic and therapeutic purposes. The Dead Sea’s shores and surface are 430.5 meters below sea level, and it takes the crown as the lowest elevation on land. The Dead Sea is renowned for its buoyancy which makes people float and consequently attracts lots of visitors.
How does salt affect the freezing point of water?
Salt particles lower the freezing point of water by moving between water molecules and impeding the formation of the crystal lattice structure of ice. With a salinity level over 40 percent, Don Juan is significantly saltier than most of the other hypersaline lakes around the world.
What is the salinity of the Dead Sea?
The Dead Sea has a salinity of 34 percent; the Great Salt Lake varies between 5 and 27 percent. Earth’s oceans have an average salinity of 3.5 percent. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this image on January 3, 2014. The ellipse-shaped lake is situated at the bottom of a basin between ...
Where is the saltiest body of water?
The world’s saltiest body of water is tucked away in a valley in one of the most extreme environments on Earth.
Where is the Labyrinth in Wright Valley?
The lower image shows a broader view of Wright Valley. Notice the network of channels just east of Wright Upper Glacier, an intricate feature eroded into dolerite bedrock known as the Labyrinth. Frozen Lake Vanda is visible to the northeast of Don Juan Pond.
How much water does a gallon of paint pollute?
A gallon of paint or a quart of motor oil can seep into the earth and pollute 250,000 gallons of drinking water.
How much water does a leaky toilet waste?
That's 65 glasses of water every day for a year. A leaky toilet can waste over 22,000 gallons of water in one year; enough to take three baths every day.
How many gallons of water does the average human have?
In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.
What is the source of fresh water?
Sources of Fresh Water. Groundwater - water which infiltrates into the ground through porous materials deeper into the earth. It fills pores and fractures in layers of underground rock called aquifers. Some of this water lies too far under the earth's surface to be extracted at an affordable cost.
How much water is available on Earth?
In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.
What percentage of the Earth's fresh water is unavailable?
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.
What percentage of water is used for cooling electric power plants?
80% of water withdrawn in the U.S. is used for cooling electric power plants and for irrigation.
How Much Freshwater is There on Earth?
As stated above, about 2.5% of the Earth’s water is freshwater. Of the fresh water available on earth, only 31% is accessible for use. About 69% of the fresh water is in form of ice cap and glacier in places like the Antarctic and Greenland ice sheet, further reducing the quantity of the available drinking water. So, if only 31% of the fresh water is available for drinking, this means 31% of 2.5%=0.00775, which equates to less than 1%. Therefore, less than 1% of the earth’s water is drinkable. In some areas, the glacier often melts in summer to provide additional drinking water. However, the amount of water from glacier melt is not sufficient to increase the available fresh water to above 1%.
Where is Available Freshwater Stored?
Almost all the available freshwater (excluding glacier) is groundwater. The groundwater emerges and feeds the streams and saturated wetlands. It acts as a reservoir that can also be tapped for various uses including in agriculture and industries. Groundwater provides approximately 40% of the drinking water.
How Many People Do Not Have Access to Clean Drinking Water?
According to 2008 WHO report on Drinkable Water and Sanitation, about 885 million people, translating to an eighth of the world’s population, have no access to safe water. About 3.6 million people die annually from diseases resulting from unsafe drinking water.
Why is protecting and managing the underground and surface water important?
Protecting and managing the underground and surface water is an essential task in ensuring availability of drinkable water. No one can create more water. But, by managing the water sources and distribution systems, people maximize the available water and make good use out of every drop. John Misachi February 14 2018 in Environment.
How much of the Earth's water is drinkable?
Therefore, less than 1% of the earth’s water is drinkable. In some areas, the glacier often melts in summer to provide additional drinking water. However, the amount of water from glacier melt is not sufficient to increase the available fresh water to above 1%.
How much of the world is covered in water?
It is a common fact that the world is covered in water. In fact, continents are like big islands in expansive oceans. About 75% of the earth is covered in water. There is no shortage of water on earth. The earth boasts of some of the largest water bodies including the oceans, lakes, and rivers that stretch across approximately two-thirds of its surface. However, despite the fact that three-quarters of the Earth are made up of water, less than 3% of the water is fresh, non-saline water. Furthermore, of the existing fresh water, not all of it is available for human consumption.
How often do atmospheric waters recycle?
However, the atmospheric waters recycle several times in a year between the atmosphere and the earth’s surface, leading to rains and snows. The rains and snow are crucial in replenishing the surface water.
How cold does salt water freeze?
Salt water freezes at a lower temperature than fresh water .saltwater freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes.
Why is the amount of salt water in all the Earth's oceans called all of it?
The amount of SALT WATER in all the Earth’s OCEANS is “all of it” because oceans are by definition “salt or sea water”. If you want to ask about VOLUME that is another question all together and Quora User provided that answer.
How many valence electrons does sodium have?
The more scientific version is that since sodium has a single valence electron, and chlorine has 7, sodium donates its valence, to make both stable, and the resulting electrical difference makes them attracted to each other. It’s called “ionic bonding”.
