Estimation of vertical mixing in the upper ocean at Station P from chlorofluorcarbons

摘要

Vertical mixing (K_v) in the upper ocean is estimated from chlorofluorocarbons (CFC's) F-11 and F-12 data collected on 5 cruiese (1982, 1985, 1992, 1993, 1995) near Station P (50N, 145W). A one-dimensional advection-diffusion model was fitted to the data from each cruise to estimate vertical mixing (K_v) and upwelling velocity (w).
