GEBCO One Minute Grid — a global grid at one arc-minute intervals, based largely on the most recent set of bathymetric contours contained within the GEBCO Digital Atlas. The grids are available to download from the British Oceanographic Data Centre (BODC) in the form of netCDF files, along with free software for displaying and accessing data ...
IBCSO is a joint project by the International Hydrographic Organization, the Scientific Committee on Antarctic Research, the General Bathymetric Chart of the Oceans and the Seabed 2030 Project. The project aims to identify and pool all Bathymetry data in the Southern Ocean and use that data to produce gridded bathymetric maps of the seafloor.

(a) Mariana Trench multibeam bathymetry data gridded at 75 m acquired on‐board the DSSV Pressure Drop overtop the GEBCO 2019 source grid (as shown in Figure 1) and the complete GEBCO 2019 grid with hillshade.

SDB methods can provide bathymetric data with varying spatial resolution, depending on the analysis method and its underlying physics. The most common methods for coastal and very high resolution (1 to 30 meters) bathymetric data are based on multispectral satellite sensors and the analytical inversion of the radiative transfer equation - often referred to as physical SDB methods [2] or ...
A global relief model, sometimes also denoted as global topography model or composite model, combines digital elevation model (DEM) data over land with digital bathymetry model (DBM) data over water-covered areas (oceans, lakes) to describe Earth's relief. A relief model thus shows how Earth's surface would look like in the absence of water or ...

In 1969, the Natural Environment Research Council (NERC) created the British Oceanographic Data Service (BODS). [3] [4] Located at the National Institute of Oceanography in Wormley, Surrey, its stated purposes were to act as the UK's national oceanographic data centre and to participate in the international exchange of data as part of the Intergovernmental Oceanographic Commission (IOC ...
