Field Activity 1984-004-FA

Identifier 1984-004-FA
Alternate names 149
Purpose This cruise was part of a continuing study of currents and sediment transport on the Continental Slope. The major objectives of the cruise were: 1) to recover Slope Array II (three subsurface moorings at stations SA, SE, and SF, and a bottom tripod at T); 2) to deploy Slope Array III (five subsurface moorings at stations SA, SE, SF, SG, and SH, and one bottom tripod at station T); 3) to recover and redeploy four surface guard buoys at stations SF and T; and 4) to conduct a hydrographic survey across the outer shelf and upper slope between 68 and 71 degrees W.
Location southern New England Shelf and slope, United States, North America, North Atlantic;
Summary Moorings deployed: 6 (#277, 278, 279, 280, 281, and 282 recovered FA 84024 OCEANUS 159 Nov. 13-24, 1984). Moorings recovered: 4 (#273, 274, 275, and 276, all deployed FA 83011 OCEANUS 149 Oct. 17-24, 1983). All mooring work was completed as planned. Bad weather curtailed mooring operations for one full day and made work difficult during most of the cruise. A moderate CTD survey was completed. The current meter on the bottom tripod system failed after about 3 weeks, probably because of a bad connecting cable. To assure near-bottom current data, an additional subsurface mooring was deployed at station T on OCEANUS cruise 154 by M. Briscoe on May 16, 1984. Hydrography: CTD: 18; XBT: 18; Salinity: 51; Suspended sediment oxygen: 15; Suspended sediment nutrients: 34.
