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: | Richness of experimental marine invertebrate communities across latitude (Competition and Predation across Latitude) from 2015-06-16 to 2018-09-12 (NCEI Accession 0291590) |
| Abstract: | This dataset contains biological and survey - biological data collected in the Coastal Waters of Southeast Alaska and British Columbia, Gulf of California, and North Pacific Ocean from 2015-06-16 to 2018-09-12. These data include species, taxon, and taxon_code. The instruments used to collect these data include Microscope - Optical. These data were collected by Gregory E. Ruiz of Smithsonian Environmental Research Center, Carmen Schlöder and Mark E. Torchin of Smithsonian Tropical Research Institute, and Amy L. Freestone and Laura J. Jurgens of Temple University as part of the "Community Effects of Competition and Predation across Latitude and Implications for Species Invasions (Competition and Predation across Latitude)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2022-04-18. The following is the text of the dataset description provided by BCO-DMO: Dataset Description: Richness of sessile marine invertebrate communities from coastal sites across a latitudinal gradient spanning the subarctic to the tropics. Communities developed for three or 12 months under nine different treatments that tested the effect of predation and competition. Caging was used to reduce predation pressure and biomass removals opened up space, a limiting resource in sessile communities. |

| Supplementary information: | Acquisition Description: Methodology: Marine invertebrate communities developed on PVC settlement panels (14 x 14 cm) hung on floating docks one meter below the water surface at local marinas at three coastal sites in each region (Panama, Mexico, California, Alaska). Communities developed for three or 12 months under the following treatments: caged (i.e. reduced predation), partial cage (i.e. procedural cage control; ambient predation) and (c) open (i.e. ambient predation). Caging material had a mesh size of 0.635 cm. These treatments were fully crossed with biomass removals of 0%, approximately 20% (actual 18%, 36cm2) or approximately 60% (actual 54%, 107cm2) panel surface scrapes. On panels assigned a removal treatment, a total of three parallel scrapes or one scrape positioned randomly on the surface of the panel to reach the 60% or 20% surface opening was performed, respectively. Communities that assembled for three months received two removal rounds (1 and 2 months after deployment) while those that assembled for 12 months received five rounds (1, 2, 6, 10, and 11 months after deployment) before the richness of each community was assessed. Experiments were initiated in Alaska in June 2015, California in May 2016, Mexico in June 2017, and Panama in December 2015. Sampling and analytical procedures: Following the assigned developmental period and approximately one month after the last biomass removal, communities were retrieved and brought back to a laboratory for assessment. Sessile marine invertebrates from each community were identified to the lowest taxonomic level possible using a stereoscope and were assigned a species or a consistent morphospecies identifier. Identifications were confirmed by taxonomic experts and DNA barcodes whenever possible. Species richness provided here is a comprehensive list of sessile invertebrate species observed per community, including species that were captured in point count (composition) measures and those that were not. |
