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: | Averages and standard deviation across species for all macrofauna found on each carbonate rock collected during R/V Atlantis cruise AT37-13 in the Pacific margin of Costa Rica from May to June 2017 (NCEI Accession 0277387) |
| Abstract: | This dataset contains chemical data collected on Alvin and R/V Atlantis during cruise AT37-13 and deployment AT37-13_Alvin_Dives at Pacific margin of Costa Rica; methane seeps in the Pacific Ocean off Costa Rica from 2017-05-21 to 2017-06-07. These data include d13C and d15N. The instruments used to collect these data include Elemental Analyzer and Isotope-ratio Mass Spectrometer. These data were collected by Dr Gregory Rouse and Dr 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 2023-01-23. The following is the text of the dataset description provided by BCO-DMO: Dataset Description: Averages and standard deviation across species for all macrofauna found on each carbonate rock collected during AT37-13. |

| Supplementary information: | Acquisition Description: Carbonate rocks were collected across seepage gradients at Mound 12 using HOV Alvin, and washed in miliQ water onboard. Before preserving, the sample was kept cold and animals were picked to sample tissue for isotope analysis. The tissue (aprox. 0.5 mg) was placed in pre weighted tin boats or combusted vials (500C overnight) and frozen at -70C. The remaining washed sample was sieved through 0.3 mm mesh, separating the sample in two fractions (a fine fraction with the meiofauna, and a coarser one with the macrofauna), both preserved in 96% Ethanol. In the laboratory, tissue samples were oven dried (60C) overnight, weighed and acidified with 12.5-25 ul 1N H3PO4 to remove inorganic C. Stable isotope measurements (d13C and d15N) were carried out using a Costech elemental analyzer coupled to a Micromass Iso-prime isotope ratio mass spectrometer (EA/IRMS) at Washington State University. |
