Anoxia occurs when dissolved oxygen concentration in the water is zero, a level where most organisms cannot survive. The western Indian continental shelf which underlies the Arabian Sea becomes anoxic under certain conditions. This article delves into the phenomenon and the impact it has on the region.
The Indian ocean is bounded by the Eurasian continental landmass on the north - responsible for the unique monsoonal seasonality in the north Indian Ocean which results in a complete reversal in the winds and surface currents every six months. Peninsular India divides the north Indian ocean into two zones - the Arabian Sea and the Bay of Bengal. Asymmetric distributions of monsoonal energy and the water fluxes make these two zone hydrographically quite different. Winds are generally stronger in...
