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: | Counts of prey species found in harbor seal scat samples collected in the San Juan Islands from 2005-2008 (Seal_response_to_prey project) (NCEI Accession 0277278) |
| Abstract: | This dataset contains biological and survey - biological data collected at WWU during deployment lab_Acevedo at Bellingham, WA from 2005-03-01 to 2008-02-01. These data include common_name, family, and species. These data were collected by Philip S Levin of National Marine Fisheries Service, Jeffrey F Bromaghin of United States Geological Survey, John M Kennish of University of Alaska, Anchorage, Monique M Lance and Steven J Jeffries of Washington Department of Fish and Wildlife, and Alejandro Acevedo-Gutierrez of Western Washington University as part of the "Responses of Seals and Sea Lions to Increased Rockfish Density (Seal_response_to_prey)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23. The following is the text of the dataset description provided by BCO-DMO: Counts of prey species found in harbor seal scat samples. Dataset Description: Counts of prey species identified in harbor seal scat samples collected from 2005 to 2008. Also see the related data set, "seal_prey_by_region", in which frequencies of occurrence are provided for prey groupings for different sampling regions within the San Juan Islands. Data and methods, including sample sizes, are described in: Lance , M. M., Chang, W.-Y., Jeffries, S. J., Pearson, S. F. & Acevedo-Gutierrez, A. 2012.

| Supplementary information: | Acquisition Description: From Lance et al.: From 2005 to 2008, fecal samples (scats) were collected seasonally over 3 collection periods: March to early June (‘spring’), late July to September (‘summer/fall’), and January to February (‘winter’). Scats were collected from 23 haul-out locations during daytime low tides. The sites were dispersed throughout the study area, represented various habitat types used by harbor seals, were the largest haul-outs where adequate sample sizes could be collected, and were easily accessible by boat. Two or three collection trips were made each season, with a target sample size of 60 scats per season per region. Samples were stored frozen. In the lab, samples were enclosed in fine mesh paint-strainer bags and cleaned using a washing machine or nested sieves. Hard parts were cleaned and stored dry. Prey were identified to lowest possible taxon using a dissecting microscope, reference fish bone collections, and published keys. |
