A bathymetric compilation around the South Orkney Islands, 1987-2017

We present a new bathymetric compilation around the South Orkney Islands here defined by the following bounding box: 47 to 37 W, 63 to 59 S. This bathymetry grid was compiled from a variety of multibeam swath bathymetry data acquired during 46 different cruises (see lineage). The data is available as a grid of approximately 100 m resolution in a GMT-compatible (2-D) NetCDF format using geographic coordinates on the WGS84 datum. Three versions of the grid are available: the first one shows only swath bathymetry data while the second and third have been merged with the global compilations from the General Bathymetric Chart of the Oceans (GEBCO), GEBCO_2014 (version 20150318) and GEBCO_2019, respectively. Funding was provided by the NERC grants NE/K012843/1 and NE/N018095/1 as well as national capability
