Bathymetric Data

Bathymetry, or the depth of the sea floor beneath the water surface, is a dominant factor in the dynamics of marine ecosystems. It impacts the distribution of sedimentary environments, benthic habitats, and contaminant accumulation. Bathymetric data is also crucial to current and sediment transport models.
