Recent Data

  1. Sea Ice and Hot Water Drilling Observation data from ANA14B

    1. Sea ice core sampling Station_logsheets_seaicesamping.xlsx The spreadsheet contains the data from the sea ice stations. ‘Station Summary’ gives an overview of the sites. ‘Sample Log' describes the ice cores taken at each site, but they have not yet been analysed, so the data from those is not yet available. The first sheet has a summary of the cores that were taken. Each of the site tabs contains any measurements we took onsite (snow depth and temperature profiles; sea ice core temperature profiles). Region: Amundsen Sea Data type: Excel spreadsheet 2. ASPeCt observations ASPeCt_ANA14B.csv Sea ice data collected using the ASPeCt (Antarctic Sea Ice Processes and Climate) protocol to record sea ice observations from a vessel. Data were recorded using the sea ice observation software, IceBox, developed by the Australian Antarctic Division. These data have also been shared with ASPeCt. Region: Amundsen Sea Data type: comma separated variables 3. CTD data under Dotson Ice Shelf 208082_20240128.csv Data from a CTD on a mooring line through a hot-water-drilled hole in Dotson Ice Shelf. The CTD was deployed about 100 m below the ice base. The hole was drilled in Jan 2022 and the data were recovered in 2024. The data columns are Conductivity [mS/cm], Temperature [°C], Pressure [dbar], Dissolved O₂ concentration [µmol/L], Sea pressure [dbar], Depth [m], Salinity [PSU], Specific conductivity [µS/cm], Dissolved O₂ saturation [%]. The data were recorded every 10 minutes. The start time is 07/02/2022 02:00:00. Region: Dotson Ice Shelf Data type: comma separated variables 4. Pressure data at the base of Dotson Ice Shelf 208085_20240128.csv Data from a pressure sensor on a mooring line through a hot-water-drilled hole in Dotson Ice Shelf. The pressure sensor was frozen into the ice about 10 m above the ice base and will eventually melt out. The hole was drilled in Jan 2022 and the data were recovered in 2024. The data columns are Time (Date and time), Pressure [dbar], Sea pressure [dbar] and Depth [m]. The data were recorded every 10 minutes. The start time is 07/02/2022 02:00:00. Region: Dotson Ice Shelf Data type: comma separated variables

  2. Sea level change over the Southern Ocean (1993-2023) calculated from multi-source satellite altimetry data

    Linear trend of sea surface elevation change during 1992-2023 (Unit: m/yr) calculated from multi-source satellite altimetry data. The initial altimetry data was obtained from CMEMS data center (https://data.marine.copernicus.eu/product/SEALEVEL_GLO_PHY_L4_MY_008_047/description). Data at only austral winter season (JFMA) was considered to estimate sea level trend. The file is created with MATLAB binary format (.mat) thus available via MATLAB program.

  3. Snow densities and temperature profiles and ice temperature profiles at four sea ice stations (snow on fast ice in front of Thwaites Eastern Ice Shelf) and one ice shelf station (snow/firn on Dotson Ice Shelf) , 2024

    Snow densities and temperature profiles from snow pits dug at four sea ice stations (snow on fast ice in front of Thwaites Eastern Ice Shelf) and one ice shelf station (snow/firn on Dotson Ice Shelf) were measured during the ANA14B cruise. A 4 m firn core was collected on Dotson Ice Shelf, and 16 ice cores (each approx. 1 m in length) were taken at SEAICE1, SEAICE2, and SEAICE3 (same location, different days, different sea ice conditions). The cores are still to be analyzed for fatty acids and isotopes.

  1. New Catalogue of Thwaites Glacier Subglacial Lakes and Their Activity Revealed by CryoSat-2 Altimetry

    This dataset unveils a newly compiled catalogue of active subglacial lakes beneath the Thwaites Glacier in West Antarctica, as detected through the CryoSat-2 satellite radar altimetry. The catalogue meticulously details each lake, outlining its boundaries, area, and elevation changes along with their 95% confidence intervals for precise scientific referencing. For citation purposes, please refer to the following article: B-H Kim, C-K Lee*, K-W Seo, W S Lee, and J-W Park. "New Catalogue of Thwaites Glacier Subglacial Lakes and Their Activity Revealed by CryoSat-2 Altimetry," currently under revision for the Journal of Geophysical Research: Earth Surface. Should you have any inquiries or require further information, Dr. Choon-Ki Lee is available at cklee@kopri.re.kr and would be pleased to assist.
