Bathymetric data represent the depth of the seafloor and are usually distributed as Digital Terrain Models (DTMs). Bathymetric data can be collected using acoustic remote sensing (e.g., multibeam echosounders, singlebeam echosounders, interferometric sidescan sonars, synthetic aperture sonars), optical remote sensing (e.g., satellite-derived bathymetry, bathymetric lidar), or by direct measurements (e.g., lead lines, sounding pole or rod, wire or bar sweep). Backscatter data represent the intensity of the acoustic or optical returns and have been linked to substrate patterns.

Marine geological data represent the nature and structure of the seafloor and sub-seafloor. Geomorphological data represent the morphology of the seafloor, which is influenced by geological processes.


Marine chemistry deals with the properties, composition, structure, and interaction of substances in the oceans. Marine chemistry data are often measured using CTD (Conductivity, Temperature, Depth) sensor that can measure a wide range of ocean water characteristics.


Marine biological data can represent for example species presence and absence, abundance, and density.


Marine physical data characterize the currents, waves, tides, and other dynamic processes that govern the motion of water and the oceans.


This section lists repositories that offer more applied datasets, such as human activities, seabed habitats, marine litter and pollution, and infrastructure.
