The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Trawl catch composition from R/V Centennial trawl surveys in the Hood Canal, WA from 2012-2013 (PelagicHypoxia project) (NCEI Accession 0278614) |
| Abstract: | This dataset contains biological and survey - biological data collected on R/V Centennial during cruise PelagicHypoxia_trawlsurveys from 2012-06-11 to 2013-10-03. These data include species. The instruments used to collect these data include GPS receiver, Midwater Trawl, and Water Depth Logger. These data were collected by Sandra Parker-Stetter of Northwest Fisheries Science Center - Seattle and John K. Horne, Julie E. Keister, and Timothy Essington of University of Washington as part of the "Consequences of hypoxia on food web linkages in a pelagic marine ecosystem (PelagicHypoxia)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-03-22. The following is the text of the dataset description provided by BCO-DMO: Trawl catch composition Dataset Description: This dataset contains trawl catch composition data from R/V Centennial trawl surveys in the Hood Canal, WA from 2012-2013. The species name, estimated number, and estimated mass are included for each tow. |

| Supplementary information: | Acquisition Description: Sampling and analytical procedures: Samples were chosen to target representative aggregations of fish as detected using multi-beam hydroacoustics. They are not designed to provide quantitative estimates of density, but rather to assess species and size composition and to collect individuals for tissue and stomach sampling. Net was a Marinovich midwater trawl, deployed using two wires and 2.5 meter FishBuster trawl doors. Trawl was fitted with a 3.2 mm knotless liner in the codend and towed at a vessel speed of 2−3 knots. Vertical opening of the trawl varied between 4.8 and 7.0 m. Catch was sorted by taxonomic group, and counted. Mass of catch was measured using a Marel M1100 series bench scale to nearest 0.1 kg. In instance of large catch of species, total number was determined by counting a weighed subsample (usueally more than 0.25 of the total catch by weight). |
