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: | Acetate and methanol turnover rates from sediment push cores collected during HOV Alvin dives during the R/V Atlantis cruise AT37-06 in Guaymas Basin, Gulf of California in December 2016 (NCEI Accession 0278671) |
| Abstract: | This dataset contains physical data collected on Alvin and R/V Atlantis during cruise AT37-06 and deployment AT37-06_Alvin_Dives in the Gulf of California from 2016-12-18 to 2016-12-24. These data include water temperature. These data were collected by Samantha B. Joye of University of Georgia and Andreas P. Teske of University of North Carolina at Chapel Hill as part of the "Collaborative Research: Microbial Carbon cycling and its interactions with Sulfur and Nitrogen transformations in Guaymas Basin hydrothermal sediments (Guaymas Basin Interactions)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-12-09. The following is the text of the dataset description provided by BCO-DMO: Acquisition Description: Methodology: Sediment samples were collected from hydrothermal areas of Guaymas Basin in the Gulf of California during cruise AT3706 of R/V Atlantis in December 2016. Push cores were obtained using the human-occupied deep diving vehicle Alvin during dives 4867 to 4872. Porewater was extracted from the sediment by centrifugation and then filtered through a 0.2 μm syringe filter. For rate measurements, approximately 3 mL of live sediment was transferred into a modified Hungate tube as described previously (Bowles et al., 2011). At each depth, triplicate live samples and one killed control were collected for the quantification of acetate and methanol turnover rates. The details of the rate measurements can be found in Zhuang et al. (2018). Instruments: Methanol and ethanol in the porewater were quantified with a purge and trap system connected to a GC–FID (SRI) (Zhuang et al., 2018). Issues of note: Due to the limited volume of porewaters, methanol and ethanol were not determined for most of the samples collected from Dives 4867 to Dive 4870. Missing data identifiers: * B.D.: Below detection limit. * nd：Not determined. nd is the default missing data identifier in the BCO-DMO data system. |
