Bathymetry and Backscatter Data Access

Marine.ga.gov.au is Geoscience Australia’s marine data discovery interface for acoustic datasets such as bathymetry, backscatter and sidescan sonar data and other marine-related products. This interface allows users to explore seafloor mapping products across Australia’s marine jurisdiction prior to downloading. The services presented here include data at both an individual survey level and as national-scale collated products. The products presented are updated on an irregular basis.

EMODnet ~ Bathymetry Viewing & Download Service

A harmonised EMODnet Digital Terrain Model (DTM) has been generated for European sea regions from selected bathymetric survey data sets, composite DTMs, Satellite Derive Bathymetry (SDB) data products, while gaps with no data coverage are completed by integrating the GEBCO Digital Bathymetry. 

The DTM with its information layers is made freely available for browsing and downloading through the Bathymetry Viewing and Download service
