Abstract

Cold and chlorophyll poor waters are used as a tracer of the cores where the deep waters touch the surface in upwelling areas of the Gulf of Cadiz. A very simple Lagrangian model of phytoplankton growth during the ascending of deep waters to the surface is implemented to diagnose vertical velocities in these cores. The diagnose combines daily images of chlorophyll and temperature to remotely sense upward velocities provided they have, in the Gulf of Cadiz, values above 9 m/d. The approach is valid for other areas subject to intense upwelling as far a local knowledge of nutrient and chlorophyll fields is implemented in the algorithms.
