| Description |
Ever since the Challenger Expedition the Indian Ocean pteropods have been recognized as important constituents of biogenic flux. Initially they were of interest only to biologists or the fishery departments and their distribution was studied only in plankton tow samples. Over the past three decades micropalaeontologists have paid attention to investigate pteropods from water and sediment samples to understand their distribution and ecological significance. Since then substantial work has been reported in the Gulf of Aqaba, Red Sea, and northern Arabian Sea, along west coast of India and around the Andaman Nicobar Archipelago. Work has neither been attempted in the Bay of Bengal nor in the northern Andaman Sea. These aragonitic microfossils have proved to be reliable indicators of bathymetry, productivity, upwelling, current circulation, intensity of Aragonite Compensation Depths, Oxygen Minimum Zone and monsoons, thus very useful in palaeoclimatic reconstructions. Works on its counterparts such as foraminifers and ostracods have been reviewed earlier and this is the first time a review of the pteropod studies in the northern Indian Ocean is being attempted, in view of the vast data generated in this region. The pteropod assemblages from two cores collected on the Irrawaddy continental shelf, in the northern Andaman Sea is also reported for the first time. The downcore distribution of pteropods suggests that no significant sea level change has occurred over the past approx. 1280 Cal yrs.
