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: | Snow pit data: temperature, density, stratigraphy at various depths from ARSV Laurence M. Gould LMG0106, LMG0205 in the Southern Ocean from 2001-2002 (SOGLOBEC project) (NCEI Accession 0112865) |
| Abstract: | This dataset contains meteorological and physical data collected on ARSV Laurence M. Gould during cruises LMG0106 and LMG0205 in the South Atlantic Ocean, South Pacific Ocean, and Southern Ocean from 2001-07-28 to 2002-09-08. These data include air temperature, density, depth, and water temperature. These data were collected by Dr Don Perovich of Cold Regions Research and Engineering Laboratory, Dr Doug Martinson of Lamont-Doherty Earth Observatory, and Dr Raymond Smith of University of California-Santa Barbara 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 2023-01-23. The following is the text of the dataset description provided by BCO-DMO: snow pit data: temperature, density, stratigraphy at various depths Dataset Description: Snowpits were dug at selected locations along the ice survey lines. Vertical profiles of snow temperature, density, grain size, and grain type were measured. Ice and slush layers were also noted. Results from the 22 snowpits examined in 2001 and the 16 snowpits examined in 2002 are summarized. Related datasets: ice thickness , ice optics , sea ice , ice properties |

| Supplementary information: | Acquisition Description: The convention is the zero height, or zero depth is the bottom of the snowpack. Snow pits were conducted to measure the temperature, salinity, density and ï„18O profile through the snow pack as well as a visual description of grain size, crystal form and hardness of each layer of snow. Many of the sites had an ice surface that was below freeboard due to snow loading. This created a salty slush layer on top of the sea ice that had salinities well above the salinity of seawater and were 10-20 cm thick in places. This slush layer also had a wicked layer of snow above it where the snow was wicking the brine up into the snow pack, 10 cm in places. In this accession, NCEI has archived multiple versions of these data. The latest (and best) version of these data has the largest version number. |
