Document Summary
In this lab we will investigate how variations in seawater (1) temperature and (2) salinity play a role in establishing vertical circulation of the ocean. We will also examine the details of how evaporation and the formation of ice affect water salinity and density. Then, we will demonstrate that surface water mixing causes a change in density and, therefore, also plays a role in the vertical circulation of the ocean. Part 1 (continued in pt 4 and pt 5): effect of evaporation and ice formation on salinity. Part 1: set-up (requires time delay during which you will complete a different section) Part 2: the effect of temperature on water density. Part 3: the effect of salinity on water density. Part 6: temperature-salinity diagram and surface water mixing. Part 7: mixing at the strait of gibraltar. When compared to the atmosphere, the structure of the ocean seems very stable.
