About 3.5% of the weight of seawater comes from dissolved salts. But just how did the salt get in there? Why is the ocean salty? Lets dive in.
Today the NADW is more salty because of the Gulf Stream; this could thus indicate a reduction of flow through the Florida Straits due to lowered sea level. Another observation is that the Southern Ocean was vastly more salty at the LGM than today.
Seawater, or sea water, is water from a sea or ocean.On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na +
Seawater temperatures have hit 100 degrees with all this heat. The consequences can be enormous to marine ecosystems, including the St. Johns River.
Bottom waters flow very slowly, driven mainly by slope topography and differences in temperature and salinity, especially compared to wind-driven surface ocean currents. [1] Antarctic Bottom Water is the most dominant source of bottom water in southern parts of the Pacific Ocean, Indian Ocean, and North Atlantic Ocean.
A Jacksonville professor is part of an international group of researchers warning of another threat from climate change: salinity levels in the ocean.
The mystery mollusks are hermaphrodites, which include both male and female reproductive organs. When it is time to release eggs, they descend and use their foot to temporarily attach to the seafloor.
Doug Peltz, popularly known as Mystery Doug, is an American science communicator and entrepreneur based in San Francisco. He is best known as the co-founder of the popular science curriculum Mystery Science, a science program used in 50% of U.S. elementary schools and recently acquired by Discovery Education . [ 2 ]
