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: | Inventory of fluid and filter samples collected for carbon composition and isotope analysis from R/V Atlantis cruise AT39-01 at the North Pond CORK Sites U1382A and U1383C during October 2017 (NCEI Accession 0291634) |
| Abstract: | This dataset contains data collected on R/V Atlantis during cruise AT39-01 from 2017-10-11 to 2017-10-15. These data include depth. These data were collected by Peter Girguis and Sunita R. Shah Walter of Harvard University as part of the "Collaborative Research: A multidimensional approach to understanding microbial carbon cycling beneath the seafloor during cool hydrothermal circulation (Subseafloor Microbial Carbon Cycling)" 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 2021-08-03. The following is the text of the dataset description provided by BCO-DMO: Inventory of fluid and filter samples collected for carbon composition and isotope analysis Dataset Description: Inventory of fluid and filter samples collected for carbon composition and isotope analysis during R/V Atlantis cruise AT39-01 at North Pond IODP CORK observatories U1382A and U1383C. |

| Supplementary information: | Acquisition Description: Detailed methodology for fluid recovery described in (Meyer et al., 2016). All fluids transferred from sampling bags by peristaltic pump through Masterflex Bio-Pharm silicone tubing and PFA or PVDF fittings. All tubing and fittings precleaned with in 10% HCl and rinsed with MilliQ water. Whole water samples transferred to pre-combusted amber glass bottles and sealed with PFTE-line lids and stored frozen at -80°C. Samples meant for DIC and alkalinity measurements sampled according to NOSAMS protocol ( http://www.whoi.edu/fileserver.do?id=75006&pt=2&p=75096 ). Poisoned samples stored at room temperature in the dark. Samples meant for DOC analysis were filtered through pre-combusted 47 mm Sterlitech GF75 filters into pre-combusted amber glass bottles sealed with PFTE-lined lids. Sampled stored at ‑40°C until analysis. Filters collected at the seafloor by the Mobile Pumping System (MPS) described in (Cowen et al., 2012). Fluids filtered sequentially through 5 µm nylon woven mesh (Spectrum Labs), Whatman GF/F and Sterlitech GF75 and stored frozen at -80°C wrapped in pre-combusted aluminum foil. |
