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: | Porewater nutrient concentrations (TN, TC, DOC, DIC, DON) from pushcore samples collected at Guaymas Basin hydrothermal vents via Alvin dives on R/V Atlantis cruise AT42-05, Nov. 2018 (NCEI Accession 0277738) |
| Abstract: | This dataset contains chemical and physical data collected on Alvin and R/V Atlantis during cruise AT42-05 and deployment AT42-05_Alvin_Dives from 2018-11-17 to 2018-11-25. These data include Carbon, Dissolved Organic Nitrogen, Nitrogen, dissolved inorganic Carbon, and dissolved organic Carbon. The instruments used to collect these data include Nutrient Autoanalyzer and Push Corer. These data were collected by Andreas P. Teske of University of North Carolina at Chapel Hill and Dr Virginia P. Edgcomb of Woods Hole Oceanographic Institution as part of the "Collaborative Research: Hydrothermal Fungi in the Guaymas Basin Hydrocarbon Ecosystem (HOTFUN)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-07-31. The following is the text of the dataset description provided by BCO-DMO: Guaymas pushcore nutrients: TN, TC, DOC, DIC, DON Dataset Description: Porewater nutrient concentrations from pushcore samples collected at two locations in the Guaymas Basin hydrothermal vents region during Alvin dives on R/V Atlantis cruise AT42-05, Nov. 2018. TN, TC, DOC, DIC, and DON concentrations at different depths within the cores are reported. |

| Supplementary information: | Acquisition Description: Alvin pushcores dedicated to nutrient analyses were sectioned to recover the 0-6cm, 6-12, and 12-18cm fractions, or the 0-10, 10-20, and 20-30cm fractions. Two ~40ml samples of sediment were placed in 50 ml Falcon tubes and were centrifuged at 3000 rpm for 15 minutes to separate porewater from the sediment. TC and TN: The sediment cakes were analyzed for %Total Nitrogen (TN) and %Total Carbon (TC). DIC, DOC, DON: 10 ml of the porewater was collected into septa vials for dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), and dissolved organic nitrogen (DON). The headspace was flushed with nitrogen and the samples were stored inverted at 4oC. All porewater analyses were performed at Louisiana State University Wetland Biogeochemistry Analytical Services.; |
