Abstract: Large scale regional differences in surface productivity as well as water column chemistry exist in the Arabian Sea environment in north-south direction. The available primary productivity data are incorporated into existing global ocean carbon flux models to estimate the potential vertical flux of carbon, and speculate on the nature of the autotrophic and heterotrophic processes, in the mixed layer and below, within the context of the observed regional chemical dichotomy. Based on these considerations, hypothetical scenarios relating to regionally variable primary productivity, retention/loss of carbon in the water column, variable mineralization in the deep sea, etc, are formulated. Field testing of these hypotheses should provide a general framework for regional Arabian Sea oceanography in the coming years, especially with respect to the Global Ocean Flux Studies.
