The vertical profile of chlorophyll concentration in waters around the Antarctic Peninsula was estimated using a statistical method (Empirical Orthogonal Function Analysis: EOF Analysis), analyzing more than 200 ship observations from the surface to 150 m. Also a method is established to predict the vertical profile from CZCS-derived concentration. The comparison in terms of vertical profile demonstrates good agreement (relative error=40%) between CZCS prediction and ship-observation. The prediction by the model only needs one input, surface chlorophyll concentration, which can be easily derived from the satellite remote sensing data.
