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: | Zooplankton densities collected from a seasonally hypoxic fjord on R/V Clifford A Barnes cruises from 2012-2013 (Pelagic Hypoxia project) (NCEI Accession 0278622) |
| Abstract: | This dataset contains biological, physical, and survey - biological data collected on R/V Clifford A. Barnes during cruises CB1002, CB1003, CB1005, CB1007, CB1009, CB975, CB979, CB982, CB986, and CB988 from 2012-06-11 to 2013-10-03. These data include density, species, and stage. The instruments used to collect these data include MultiNet and Sea-Bird SBE 43 Dissolved Oxygen Sensor. These data were collected by Dr Sandra Parker-Stetter of Northwest Fisheries Science Center - Seattle and Dr John K. Horne, Dr Julie E. Keister, and Dr 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 2019-04-04. The following is the text of the dataset description provided by BCO-DMO: Zooplankton densities by species and life stage in a seasonally hypoxic fjord. Dataset Description: Depth-stratified zooplankton net sampling in Hood Canal June to October, 2012-2013. |

| Supplementary information: | Acquisition Description: We conducted day/night paired zooplankton sampling in Hood Canal in June-October, 2012 and 2013. Sampling stations included Dabob, Union, Hoodsport, Duckabush, and Twanoh. A Hydrobios MultiNet (five-net capacity) was used to collect depth-stratified and full water column samples. Net mouth area was 0.25 m2; 200- and 335-um mesh nets were used to sample different size zooplankton. Nets were towed obliquely at 1-2.5 knots (slower tows for smaller mesh size), with inner and outer flow meters to measure water volume sampled. For the depth-stratified sampling, depth layers were based on the dissolved oxygen profiles from CTD casts. In the laboratory, zooplankton were quantitatively subsampled and microscopically counted. All individuals were identified to species or larger taxonomic grouping, and by life stages for some species, within each sample. |
