The layer is one of the 25 layers that make up the global seafloor geomorphic features map (Harris et.al. 2014). Escarpments are “an elongated, characteristically linear, steep slope separating horizontal or gently sloping sectors of the sea floor in non-shelf areas. Also abbreviated to scarp” (IHO, 2008). Escarpments, like basins, overlay other features (i.e. other individual features may be partly or wholly covered by escarpments). Thus features like the continental slope, seamounts, guyots, ridges and submarine canyons (for example) may be sub-classified in terms of their area of overlain escarpment.Escarpments were calculated based on the gradient of the SRTM30_PLUS model. false Escarpment geomorphic feature layer fid 1 1 xsd:int the_geom 1 1 gml:MultiPolygonPropertyType UniqueID 1 1 xsd:string Geomorphic 1 1 xsd:string area_km2 1 1 xsd:double
