GEOLOGY & GEOMORPHOLOGY
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.

Characteristics of the seabed influences physical, chemical and biological processes in the ocean, both directly and indirectly. The angle and direction of slope guides the currents and affects how and where waves break, and the chemical and biological components of seawater in an area is therefore determined by the horizontal and vertical transport of water. Sediment composition may benefit or exclude biological activity and marine habitats such as coral reefs and seaweed growth, thus controlling food sources and living conditions for different species of benthic dwellers further up the food chain.
As with bathymetry, geology and geomorphology are important to map when creating nautical charts, as rocky outcroppings, shallow sandbanks and underwater obstacles may impede navigational safety.
