Scientific Purpose/Goals: Recover two subsurface moorings from the dump site which were deployed in September 1989. Collect sediment samples for studies of benthic infauna, microbiology, heavy metal and organic geochemistry. Overall objective of the sampling is to extend our study (initial survey on ATLANTIS cruise 122) of the sea floor to determine where particles from sewage sludge are being deposited as a result of discharge in the dump site (2,250-2,750 m water depth). Samples were also taken in control sites to the northeast of Hudson Canyon at about 2,500 m water depth. Reoccupied two sites on the southern flank of Georges Bank for coring and grab sampling.
