Seasonal and inter-annual variability of plankton chlorophyll and primary production in the Mediterranean Sea: a modelling approach

This study presents a model of chlorophyll and primary production in the pelagic Mediterranean Sea.A 3-D-biogeochemical model (OPATM-BFM) was adopted to explore specific system characteristics and quantify dynamics of key biogeochemical variables over a 6 yr period, from 1999 to 2004.We show that, on a basin scale, the Mediterranean Sea is characte
