What is “salt” in the ocean? Salt that we eat, and call salt is only 1 kind out of hundreds of kinds of salts. Table salt, a common salt in ocean water is called SODIUM CHLORIDE formula: NaCl The definition of salt is any… A metal atom and a nonmetal atom (or complex of atoms) that bond together by transferring their electrons to each other (metals become + charged ions, and the nonmetals become – charged ions). Most salts can dissolve in water. They are AQUEOUS.
Concentration of salt in ocean water Is about 35 pounds per 1000 pounds. This is called 35 parts per thousand The most common salt in ocean water is SODIUM CHLORIDE. Calcium, Magnesium Sodium and Potassium are metals. They all make positive ions, and all can bond to the negative ions: bicarbonate, sulfate, chloride, and bromide. Principle Constituents of Ocean Water Chemical ions~Parts per 1000 Calcium 0.4 Magnesium 1.3 Sodium 10.7 Potassium 0.4 Bicarbonate 0.1 Sulfate 2.7 Chloride 19.4 Bromide 0.1 Totals: 35.1
Zones of the Oceans… The fancy names are not important to memorize. Some zones have light, some are dim, and most are dark. Plants only live in the zones with light.
Sunlit zone is only about 600 feet deep. All of the ocean photosynthesis occurs here. Photosynthesis is where plants can convert CO2 and water into sugars such as glucose or C6H12O6. Food is abundant, and many animals live here too. The primary producers (plants that end up as food in a food web) are algae, seaweeds, and phytoplankton (plants). Corals are actually ANIMALS!
In this sunlit zone, most of the fish of the oceans live, including…
