General bathymetric chart of the oceans (GEBCO) bathymetry data

Description

Received from the British Oceanographic Data Centre (BODC) this resource has two datasets. The first is a global one arc-minute grid released in 2003, updated 2008 and is based on the most recent set of bathymetric contours contained within the GEBCO Digital Atlas. The second is a 30 arc-second grid generated by combining quality-controlled ship depth soundings with interpolation between sounding points guided by satellite-derived gravity data.

This dataset provides global gridded elevation data for land surfaces and gridded depths for the world's oceans. Elevations and depths are in metres, at one metre intervals.

Spatial reference and data type

Coordinates are in decimal degrees. The data are in raster format. Other data formats can be accommodated, as the Geospatial Centre has access to a number of conversion utilities.

Data access

To request this data, please fill out the Ask-Us form and include which layers (shapefiles) you are interested in obtaining. The dataset will be shared with you via OneDrive upon completion of the data release agreement form. You may also make an in-person appointment using the same form. The data can also be downloaded from the the BODC website.
