Gridded bathymetric compilation of Tristan da Cunha from multibeam echosounder data collected by multiple vessels (1996-2019)
We present a new gridded bathymetric compilation around Tristan da Cunha here defined by the following bounding box: 5 to 16.8W, 33 to 43.5S.
This bathymetry grid was compiled from a variety of multibeam swath bathymetry data acquired during 7 different cruises (see lineage). The data is available as a grid of 0.001 degrees resolution in three different formats: NetCDF, ArcView ASCII and GeoTIFF formats using geographic coordinates on the WGS84 datum.
This grid is an output of the UK FCDO ''Blue Belt'' program and the following Natural Environment Research Council (NERC) BAS-ODA fundings: NE/R000107/1 and NE/T012439/1.

- Statement
- The data has been processed using different software including CARIS and MB-system. Final quality control was undertaken manually to remove any outliers in the source datasets. This involved cleaning much of the raw data using the "mbedit" program from MB-system.
