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: | Macrofaunal diversity and abundance characteristics of sediment push cores collected by HOV Alvin during R/V Atlantis cruise AT37-13 and AT42-03 in the Pacific margin of Costa Rica in 2017 and 2018 (NCEI Accession 0277712) |
| Abstract: | This dataset contains biological data collected on Alvin and R/V Atlantis during cruises AT37-13 and AT42-03 and deployments AT37-06_Alvin_Dives and AT42-03_Alvin_Dives at Pacific margin of Costa Rica; Guaymas Basin from 2017-05-21 to 2018-11-05. These data include biomass. These data were collected by Gregory Rouse and Lisa A. Levin of University of California-San Diego as part of the "Collaborative research: Quantifying the biological, chemical, and physical linkages between chemosynthetic communities and the surrounding deep sea (Costa Rica Seeps)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-04-22. The following is the text of the dataset description provided by BCO-DMO: Acquisition Description: Sampling of sediment macrofauna took place on the Pacific margin of Costa Rica aboard the RV Atlantis using the submersible Alvin over May-June 2017 (AT37-13) and October-November 2018 (AT42-03), covering a depth range of 377-1908 m. Push cores were used to collect sediment samples from five methane seep sites (Jaco Scar, Mound 12, Mound 11, Parrita Seep, and Quepos Landslide) and surrounding non-seep sites. Samples were obtained under license of a collecting permit issued by the Ministerio de Ambiente y Energía of Costa Rica. In total, 76 cores (6.4 cm internal diameter, 10 cm depth) representing 38 distinct sampling points (two cores per sampling point) were collected and analysed. |
