2. T-S diagrams (20 pts). Use the T-S diagram below and answer the following questions: a) What are the values of o, for seawater at (1) in situ temperature of 1 °C and salinity of 35.5 PSU, and (2) in situ temperature of 18 C, and salinity 34.0? b) what do these , values mean in terms of density at atmospheric pressure? c) For water at 16 °C and salinity of 34 PSU what change in temperature would cause a change in density from 1.025 x 103 kgm-3 to 1.026 x 103 kgm-3 at constant salinity? What change in salinity would cause the same change at constant temperature? A 7-S diagram contoured in values. 20 24.0 24.5 25.0 25.5 15 27.5 3 10 28.0 26.0 28.5 26.5 5 lines of 29.0 constant ot 0-27.0 33.5 34.0 34.5 35.0 35.5 36.0 36.5 salinity (permille)

Explanation / Answer

a) line of constant at 1 degree and 35.5 PSU is 28.5.

b) line with value of 24.5

c) line with value of 25.0. In General, if a sample with a density of 1.026 g/cm3 then it has value of T = 26.

thus value of temp for 34 salinity for 26 curve is about 11o C.

For constant temp of 16 degree, salinity atcurve 26 is about 34.7 PSU.
