Purpose
Abstract SO93 evaluated the Holocene and Late Pleistocene burial rate of organic and anorganic carbon along the N-S Profile in the Bay of Bengal. Main goals were the estimation of vertical particle flux and the recent CO2 transfer from the atmosphere into the water column but also the effects of hurricanes on the Holocene shelf sedimentation. The HSDS was usually operated with a "mean" sound velocity near 1500 m s-1, a slightly higher velocity than automatically estimated by internal calculations. Most bathymetric information was collected along single profile lines, where the morphological information was needed to interpret the high-resolution data of the PARASOUND. Sometimes on-line bathymetric data were used to monitor the meandering turbidite channels and direct the ships course following the always changing direction of the channel. Selected segments of deep-sea channels were systematically mapped to determine the location of the active channel.
