The cross product satisfies the general identity. (7). Note that is not a usual polar vector, but has slightly different transformation properties and is therefore a so-called pseudovector (Arfken 1985, pp. 22-23). Jeffreys and Jeffreys (1988) use the notation to denote the cross product.
Six Most Abundant Elements Dissolved in Ocean Water. Sodium chloride is the prevalent ionic compound found in seawater, accounting for about 85 percent of the dissolved salt. Sodium chloride is better known as common table salt. The salty taste of ocean water is due to the presence of sodium chloride in the water. When measuring the concentration of salt ions in seawater, the ratio of the six abundant ions remains constant. In other words, if you dried up all the water in the ocean, each remaining pile of salt, regardless its location in the world, would contain about 55.03 percent chloride, 30.59 percent sodium.
The commonest way to record salinity is to measure the amount of salt in 1000g of water, so it is referred to as âparts per thousandâ or ppt. Most of the ocean has a salinity of between 34ppt and 36ppt. Some properties of water are changed by having salt in it: 1  Salt makes seawater more dense than freshwater.here are many chemicals in seawater that make it salty. Most of them get there from rivers carrying chemicals dissolved out of rock and soil. The main one is sodium chloride, often just called salt. Most seawater has about 35g (7 teaspoons) of salt in every 1000g (about a litre) of water.
