Summary of Activity and Data Gathered: This cruise continued the effort started 5 years ago for the Georges Bank Monitoring Program. Samples were collected to determine the distribution of barium (a component of drilling mud) around the Bank and with depth in sediments. Samples were also collected to continue the monitoring of benthic infauna. Bathymetry, near-bottom water samples, cores and grabs were also collected in Franklin Basin, just north of Georges Bank. This work investigated the anoxic sediments of this region. The hydraulically damped corer recovered excellent samples on the Bank operating through the stern A-frame using the trawl winch. Part of the success was due to the exceptionally calm seas for the first 2 days of the cruise. In anything but calm seas, it would be wise to use this equipment off the starboard side of the ship using the Marky winch and the power davit recently installed. At this position on the ship, equipment is subjected to much less heave while on station. Bathymetry: 912 km; Oxygen/nutrient water samples: 5; Salinity samples: 19; XBTs: 9; Gravity cores: 5; Grabs: 100; Hydraulically damped cores: 31.
