PPT-The Density of Seawater

Part 5 Density Zones The ocean is broken into density zones The 3 density zones are controlled by Temperature salinity Zone 1 Surface zone the upper layer of the ocean least . First lecture:. 1.

Isopycnal surfaces . 70% of the Earth is covered by . o. cean water!. Seawater Composition. Ocean water is made up of three things:. 1.) Dissolved Gases . 2.) Organic Molecules. 3.) Salts. Seawater is a solution.. Solution: Made of a solute and a solvent. . desalination. . market. Problem. 1/3 of world population live in the countries with water shortage problems;. according to the experts' forecast this figure will increase to 2/3 by 2025.. Conclusion: considering acute fresh water deficiency, seawater desalination issue has become more and more burning.. Lecture 32 . The Antarctic Ice Record. Much subsequent . paleoclimate. effort has focused on . δD. in ice cores from Antarctica and Greenland.. The . Vostok. core from Antarctica went back 400 . ka. The solubility and saturation value for gases in seawater increase as temperature and salinity decrease and as pressure increases.. 1. .
