Unformatted text preview: Chapter 8 Circulation and Ocean structure Density Sigma-t t = sigma-t = (density- 1)*1,000 Example: Density = 1.02677 g/cm3 (1.02677-1) = 0.02677 0.02677*1,000 = 26.77 = sigma-t = t What are the typical t values of the world ocean? 1 Density in T-S space How do we define a water mass? Ocean density layers Density profile - density vs depth 2 Temperature and salinity profiles T-structure of surface layer and vertical mixing of surface layer Age of a water mass What do we really mean by "age"? Determined by radio-active tracers Tritium C-14 3 Concepts in ocean mixing Thermohaline circulation Down welling and up welling Convergence and divergence Continuity of flow Atlantic Ocean's S&T Atlantic S&T 4 Arctic Ocean S&T Pacific Ocean Indian Ocean 5 Sampling 6 ...
