A multibeam-bathymetric compilation for the southern Amundsen Sea shelf, 1999-2019
We present a new compilation of multibeam-bathymetric data for the inner Amundsen Sea continental shelf beyond Thwaites and Pine Island glaciers (bounding box: 100W to 110W, 74S to 75.5S). The region includes Pine Island Bay, marine areas offshore the Thwaites Ice Shelf to the Crosson Ice Shelf, and covers an area of 74,750 km2. The bathymetric grids were compiled from all available multibeam echosounder (MBES) data acquired by UK, German, USA and Korean scientific cruises to the area between 1999 and 2019 (see lineage). Three grids of sea floor elevation data are available in a range of formats (ESRI ascii interchange format and GMT-compatible netCDF 4byte float): a 50-m resolution grid with no interpolation, a 50-m grid interpolated up to 300 m from cells with real data, and a 500-m resolution grid with no interpolation. Note that these grids have not been merged with regional bathymetric grids and, therefore, do not have continuous coverage (i.e. cells are only populated where multibeam data exist).

- Statement
- Quality control was undertaken manually to remove any outliers in the source datasets. This involved cleaning of the raw data during or after each individual cruise, and then again after compiling the datasets. For cruise NBP19-02, one of the principal datasets in the grid, the raw data cleaning was done using the "mbedit" and "mbeditviz" programs from MB-system. Other BAS datasets were also cleaned using "mbedit".
