Carbon dioxide and nitrous oxide in the North Indian Ocean

Abstract

The understanding of biogeochemical cycling of carbon dioxide and nitrous oxide in the oceans is essential for predicting the fate of antbropogenically emitted components. The North Indian Ocean, with its diverse regimes, provides us with a natural laboratory that can unravel tbe mechanisms controlling these gases with implications for the global aquatic bodies. In this review we discuss the anthropogenically impinged global budgets for these gases, summarize our results, largely collected under the Global Change Programme from the North Indian Ocean and evaluate the contributions from this region to the global sea-to-air fluxes.
