Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Location: Mid-Atlantic Continental Shelf, Wilmington Canyon, Georges Bank, Lydonia Canyon, New Jersey Shelf, United States, North America, North Atlantic;
Principal Investigator(s): Bradford Butman

Information to be Derived:
Summary of Activity and Data Gathered: All moorings were deployed as planned with the exception of the tripod at Station L. The instrument malfunctioned on deck and will be deployed on the November OCEANUS cruise. Because of the two days of bad weather and the return to Woods Hole for medical attention, there was no time for hydrography on Georges Bank. All moorings were recovered as planned except for a lost surface mooring at Station MAB and the tripod system at GBK. The surface buoys at GBK were left until the tripod is recovered. Moorings deployed: 8 (#203, 204, 209, 210, 212, 213, and 218 recovered FA 81009 OCEANUS 95 Apr. 3 - May 6, 1981; #206 recovered FA 81002 OCEANUS 91 Jan. 16-22, 1981). Moorings recovered: 5 (#193, 194, 196 partial, 197, and 198 deployed FA 80009 OCEANUS 81 May 23 - Jun. 1, 1980). Surface buoys deployed: 6 (K, M, Q, U, V, R); Surface buoys recovered: 3 (A, S, T); Lost: 1 VACM (from #198). CTD stations: 3; XBT stations: 16; Surface salinity: 15; Grab samples: 1.

Notes: Tripod at L malfunctioned; will be deployed Nov. 1980 OCEANUS cruise. Tripod at GBK line parted; will be recovered on Nov. 1980 OCEANUS cruise.
