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: | Ice core physical properties from ARSV Laurence M. Gould LMG0106 in the Southern Ocean from July 2001 (SOGLOBEC project) (NCEI Accession 0278857) |
| Abstract: | This dataset contains physical data collected on ARSV Laurence M. Gould during cruise LMG0106 from 2001-07-28 to 2001-08-18. These data include salinity calculated from CTD primary sensors and water temperature. The instruments used to collect these data include Ice Corer. These data were collected by Dr Chris H. Fritsen of Desert Research Institute as part of the "U.S. GLOBEC Southern Ocean (SOGLOBEC)" project and "U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-01-22. The following is the text of the dataset description provided by BCO-DMO: ice core physical properties Dataset Description: A key component of our program was ice properties studies. The goal was to describe the physical and morphological properties of the snow cover and the ice cover. This includes determining the distribution of snow depth, ice thickness, and flooded ice, as well as the salinity and crystallographic structure of the ice. There were three elements to this work: snow and ice surveys, ice cores, and snow pits. In 2001, over 120 ice cores, at more than 30 sites were taken for analysis. Typically four cores were taken at each site; one for temperature, salinity, and oxygen isotopes; one for structural analysis; and two for biology. In 2002, cores were taken at 21 sites and analyzed for temperature, salinity, oxygen isotopes, and structure. Related datasets: ice thickness , snow pits , sea ice , ice optics |

| Supplementary information: | Acquisition Description: A Sipre 3-inch core barrel was used. The cores were drilled by hand to avoid contamination by oil and gasoline. Both the ice core length and the ice thickness were recorded. There was often a discrepancy between these values due to gaps in the core or the inability to obtain a core sample from the bottom part of the ice floe. Vertical thin sections were made from the structure cores. These thin sections were photographed using transmitted natural light and through crossed-polaroids to analyze the crystallographic structure of the ice. The relative amounts of granular and columnar ice were determined. Averaging all cores together there was 66% granular ice and 34% columnar in 2001. In 2002, there was 78% granular and 22% columnar ice. The structural analysis of the thin sections was performed by A.J. Gow. |
