Fish abundance data from MOC-10 trawls from the ARSV Laurence M. Gould, RVIB Nathaniel B. Palmer LMG0104, NBP0104, LMG0203, NBP0204 from the Southern Ocean, 2001-2002 (SOGLOBEC project) (NCEI Accession 0112166)
This dataset contains biological and survey - biological data collected on ARSV Laurence M. Gould and RVIB Nathaniel B. Palmer during cruises LMG0104, LMG0203, NBP0104, and NBP0204 from 2001-04-30 to 2002-08-07. These data include abundance, biomass, depth, depth_close, depth_open, family, and species. The instruments used to collect these data include MOCNESS10. These data were collected by Dr Joseph J. Torres of University of South Florida as part of the "U.S. GLOBEC Southern Ocean (SOGLOBEC)" project and "U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.

Supplemental Information | Acquisition Description: Methodology: Field work was done on four cruises conducted during the austral fall and winter. Cruises 1 (2001) and 3 (2002) were aboard the Antarctic Research Support Vessel (A.R.S.V.) Laurence M. Gould from April to June; cruises 2 (2001) and 4 (2002) were aboard the Research Vessel Ice Breaker (R.V.I.B.) Nathaniel B. Palmer from July to September. Samples were collected with a 10m2 MOCNESS (MOC-10) outfitted with six 3mm mesh nets. The initial net fished obliquely to depth with each subsequent net fishing a discrete depth layer upward to the surface. At stations with depths>1000 m, layers sampled were 0-1000, 1000-500, 500-200, 200-100, 100-50, and 50-0 m. At stations with depths >500 m, layers sampled were 0-500, 500-300, 300-200, 200-100, 100-50, and 50-0 m. At stations with depths <500 m, sample layers were modified to provide optimal coverage of the water column with the five discrete-depth nets. A total of 62 MOC-10 trawls were done, 22 each in the fall of 2001 and 2002, and 9 each in the winter of 2001 and 2002 (Table 1). Trawls were conducted at various times throughout the day. In the fall, 37 trawls occurred at night (18:00-06:00 h), 1 in daylight, and 6 at dusk. In the winter, seven trawls occurred at night, seven in daylight, and four at twilight. Towing speed for all tows was 1.5-2.2 knots. Tows in pack ice were conducted in leads created by the ship's wake with the A-frame in to minimize the chance of hooking the wire on ice floes. When ice conditions dictated, the ship first traversed a trawling transect prior to deployment and then backtracked over the same course through the created lead to insure that adequate speed could be maintained for the duration of the tow.
