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: | Modeling bio-energetics for South Pacific Gyre marine sediment at site U1370 on 2019-12-20 (NCEI Accession 0291997) |
| Abstract: | This dataset contains biological and chemical data collected in the South Pacific Ocean on 2019-12-20. These data include biomass and total organic Carbon. These data were collected by Doug LaRowe and James Bradley of University of Southern California as part of the "Develop a 1D biogeochemical-evolutionary model for deep sediments (BIO-SED)" project and "Center for Dark Energy Biosphere Investigations (C-DEBI)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-12-20. The following is the text of the dataset description provided by BCO-DMO: This data relates to the calculation of bio-energetics for South Pacific Gyre marine sediment (site U1370). Dataset Description: This data relates to the calculation of bio-energetics for South Pacific Gyre marine sediment (site U1370). This project quantifies the role of microbial necromass and organic carbon as a power source to living microorganisms in marine sediments. The project utilizes a physiochemical model of marine sediment bioenergetics using data available in the literature and well-established modeling constructs. Data sources and model formulation are described in Bradley et al. 2018 (https://doi.org/10.1002/2017JG004186). For modelling South Pacific Gyre sediments, cell abundance and particulate organic carbon concentrations were determined for site U1370 (IODP Expedition 329) based on published analysis of extracted drill cores: D’Hondt et al. 2015 (https://doi.org/10.1038/ngeo2387); D’Hondt et al. 2011 (https://doi.org/10.2204/iodp.proc.329.2011). For modelling global cell abundance, we use the formulation described in Parkes et al. 2014 (https://doi.org/10.1016/j.margeo.2014.02.009). |
