We present two new gridded bathymetric compilations of the Orkney Passage, Scotia Sea here defined by the following bounding boxes: 39.1 to 39.6 W, 60.55 to 60.7 S and 41.7 to 42.6 W, 60.45 to 60.8 S. These bathymetry grids were compiled from a variety of multibeam swath bathymetry data acquired during 12 different cruises (see lineage). The data is available as grids of 50 m resolution in a GMT-compatible (2-D) NetCDF format using geographic coordinates on the WGS84 datum. This grid was compiled in support of the ongoing monitoring efforts in and around Orkney Passage as part of the Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA) programme and preceding BAS NC projects, and the Dynamics of the Orkney Passage Outflow (DynOPO) project. Funding was provided by the NERC grants NE/K012843/1 and NE/N018095/1 as well as national capability

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. Quick views are also available in the corresponding folder. Funding was provided by the NERC grants NE/K012843/1 and NE/N018095/1 as well as national capability
