The Seafloor Geomorphology, US West Coast dataset contains a digital seafloor geomorphic features map (GSFM) of the ocean within the Exclusive Economic Zone of the West Coast, USA. This dataset is a subset of a global dataset that includes global spatial data layers for 29 categories of geomorphic features, defined by the International Hydrographic Organisation and other sources.
The GSFM provides the basis for the first global estimates of physiographic statistics (area, number, mean size, etc.) for terraces, basins, plateaus, abyssal ridges, rift valley segments, glacial troughs, escarpments, sills, trenches, troughs, fans and bridges.
Certain geomorphic features are known to be good surrogates for biodiversity. For example, seamounts support a different suite of species to abyssal plains.
