PPT-OCEAN CIRCULATION Density of seawater

EFFECT OF TEMP gt EFFECT OF SALINITY OCEAN LAYERS SURFACE MIXED ZONE less dense upper ocean temp and salinity change often TRANSITION ZONE fairly constant density acts as barrier between surface and deep zones. Susan Howard. Earth & Space Research. Basically – why and how the ocean and atmosphere MOVE!. www.ametsoc.org . There are many scales of motion: . From . BIG. . to . very small. Today – I will just cover the basic large scale, GLOBAL circulation.. First lecture:. 1. Depth and Pressure . 2. Temperature. 3. Heat. 4. Potential temperature. Second and third lectures:. 1. Salinity. 2. Density. 3. Freezing point, sea ice. 4. Potential density. 5. 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. . 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 . A diver descends from a salvage ship to the ocean floor at a depth of 35 m below the surface. The density of ocean water is 1.025 x 10. 3. kg/m. 3. .. a.. Calculate the gauge pressure on the diver on the ocean floor.. Density Controls. Controlled by:. 1.) Temperature. 2.) Salinity. 3.) Pressure. Density increases with increasing salinity. Density increases with decreasing temperature.. Density increases with increasing pressure.. ) . Fall, 2016 L. Talley. First lecture:. Accuracy and precision; other definitions. Depth and Pressure . Temperature. Salinity and absolute salinity. Density. Sea ice, freezing point. Talley SIO 210 (2016). The Waters of the Ocean. 1) A . molecule . of water is made of . two hydrogen atoms . and . one atom of oxygen. 2) Water molecules are held together by . hydrogen bonds . (weak and easily broken). 3) The states(phases) of water are . Oceans and Temperature. Ocean surface temperature strongly correlates with latitude because . insolation. , the amount of sunlight striking Earth’s surface, is directly related to latitude.. 1.
