Summary of Results:

Moorings recovered: 7(#277,278,279,280,281,282 all deployed #84004 OCEANUS 149 Mar. 12-19, 1984; #283 deployed #84031 OCEANUS 154 May 16-23, 1984). OC159 was the last in a series of 3 cruises conducted as part of a USGS program to study currents and sediment transport on the Continental Slope. The program is supported by the USGS and by the Minerals Management Service. Despite the weather, all major scientific objectives were accomplished. All moorings were recovered and a moderate CTD survey was completed. One section was repeated 3 times during the cruise which should illustrate temporal changes in suspended sediment during typical storm conditions. A 1-m Sea Tech transmissometer was used to make suspended sediment observations. The oxygen sensor on the CTD failed early in the cruise.
