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: | Measurements of nutrient flux and denitrification in clam aquaculture sediments from 2013-05-01 to 2013-11-30 (NCEI Accession 0278186) |
| Abstract: | This dataset contains chemical data collected at shoreside Virginia during deployment Cheerystone_Inlet from 2013-05-01 to 2013-11-30. These data include Ammonium, Dissolved Organic Nitrogen, dissolved Oxygen, dissolved inorganic Carbon, and reactive phosphorus (PO4). The instruments used to collect these data include Isotope-ratio Mass Spectrometer and Multi Corer. These data were collected by Craig Tobias of University of Connecticut, Michael F. Piehler of University of North Carolina at Chapel Hill, and Bongkeun Song and Mark J. Brush of Virginia Institute of Marine Science as part of the "Microbial Regulation of Greenhouse Gas N2O Emission from Intertidal Oyster Reefs (Oyster Reef N2O Emission)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-05-26. The following is the text of the dataset description provided by BCO-DMO: Measurements of nutrient flux and denitrification and DNRA rates in clam aquaculture sediments.

| Supplementary information: | Acquisition Description: In May and July 2013, 16 randomly selected clam beds and 4 uncultivated sites and in November 2013, 7 randomly selected clam beds and 3 uncultivated sites were sampled at the Cheerystone Inlet of VA Eastern Shore. Uncultivated sites were located approximately 20 m from the clam beds, a distance chosen to reduce any influence of aquaculture on the control sediments and at a water depth similar to that of the clam beds. 60 cores were collected in May and July (20 total sites during each month), and 30 cores were collected in November (10 total sites). Cores were not treated as replicates, but were used to conduct concurrent incubations to measurement of denitrification and DNRA rates by isotope-pairing techniques. The details of methods are published in Murphy et al. (2016). DOI: 10.1002/lno.10305. |
