Particle fluxes in the Bay of Bengal measurEd. by sediment traps
Abstract
Particle fluxes were measured between October, 1987 and March, 1988 using six automated time series sediment traps at three locations in the northern, central and southern Bay of Bengal. Particle fluxes varied between 16.8 and 345 mg m/2 day/1 with generally higher fluxes during December and January. Annual fluxes decreased from 41.2 g m/2 y/1 in the northern Bay of Bengal to 19.69 g m/2 y/1 in the southern Bay of Bengal. As compared to the Arabian Sea, the observed particle fluxes in the Bay of Bengal are higher by a factor of 1.5 despite the fact that the primary productivity here is lower. In the central and southern Bay of Bengal, the deeper traps show much higher fluxes compared to the shallow traps indicating significant lateral transport and scavenging of particles in the water column
