Trawl catches, abundance, and biomass from F/V Sea Eagle and F/V Frosti cruises in the Northeast Pacific from 2000-2002 as part of the U.S. GLOBEC program (NEP project) (NCEI Accession 0114641)
This dataset contains biological and survey - biological data collected on F/V Frosti and F/V Sea Eagle during cruises FR0206-01, FR0206-02, FR0208, SE0005, and SE0007 in the North Pacific Ocean from 2000-05-29 to 2002-08-17. These data include species and stage. The instruments used to collect these data include Nordic 264 Rope Trawl. These data were collected by Dr Robert L Emmett and Richard D Brodeur of Northwest Fisheries Science Center - Newport and Suzan S Pool of Oregon State University as part of the "U.S. GLOBEC Northeast Pacific (NEP)" 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 2019-11-28.

During juvenile salmonid trawling cruises, additional sampling included CTD profiles, neuston net tows, and Niskin bottle water collections for chlorophyll a. At most stations, data on all parameters were collected.
Results: Detailed analyses of the nekton trawl catches for 2000 are presented in Brodeur et al. (2004) and for jellyfish for both years in Suchman and Brodeur (2005).

Supplemental Information | Acquisition Description: Methods At each station, a Nordic 264 rope trawl built by Nor'Eastern Trawl Systems, Inc. was towed in surface waters by a chartered fishing vessel (F/V Sea Eagle in 2000 and F/V Frosti in 2002). It was towed with about 300 m of warp for 30 min at 1.5 m/sec with a pair of 3.0-m foam-filled trawl doors and 90.7-kg weight chains to spread the mouth open. Except for two mid-water trawling events, six A-4 Polyform floats were clipped to wingtips and the headrope to fish the trawl at the surface. The trawl has a maximum mouth opening of approximately 30-m wide x 18-m high. Mesh sizes ranged from 162.6 cm in the throat of the trawl near the jib lines to 8.9 cm in the codend. To maintain catches of small fish and squid, a 6.1-m long, 0.8-cm knotless liner was sewn into the codend. All but several tows were 30 min in duration. The majority of trawls were done during daytime, although a few were done at dawn and dusk and two diel series were completed in 2002. All juvenile salmon caught were immediately frozen for laboratory analysis. All fish, squid, and large jellyfish caught were counted and up to 50 of them measured at sea. However, when very large catches of a species occurred, a subsample was measured, counted, and weighed; remaining individuals were mass weighed and total count estimated from known number/kg. When the trawl was full, weight of the total catch was estimated and species counts derived from a subsample as just described. Catches were standardized to number per 10 6 m 3 . In the laboratory, all frozen juvenile salmonids were weighed prior to dissections for subsamples of growth, condition, pathology, genetic analysis, and food habits. As large subadult/adult salmonids were released shortly after being captured, their weights were estimated from length-weight regressions. Also, common species of non-salmonid fish and squids not weighed at sea had their weights computed from length-weight regressions where their lengths were available. For those individuals without length data, station or cruise-wide average of number/kg was used to estimate weights. In this accession, NCEI has archived multiple versions of these data. The latest (and best) version of these data has the largest version number. |
