Turbulent <strong>diffusion</strong>….z/zoS D D oT( z) = ( T − T )e + T , z =κzwIn recent years κ z has been found to be ~ 0.1 cm 2 /secover much of <strong>the</strong> ocean <strong>in</strong>terior. For <strong>the</strong> N. Pacific,<strong>the</strong> scale height z o can be taken to be ~ 600 m.This suggests that w ~ (0.1)/(6x10 4 ) ~ 10 −6 cm/sec .[small <strong>and</strong> unmeasurable]
