The layer is one of the 25 layers that make up the global seafloor geomorphic features map (Harris et.al. 2014). The abyss is the area of seafloor located at depths below the foot of the continental slope and above the depth of the hadal zone (defined as deeper than 6,000 m). The abyssal classification feature layer was created by clipping a layer representing the ocean with the shelf, slope and hadal layers. The resulting layer was then classification into areas of plains, hills and mountains based on variation in topography. false Abyssal classification layer fid 1 1 xsd:int the_geom 1 1 gml:MultiPolygonPropertyType Class 1 1 xsd:string Geomorphic 1 1 xsd:string area_km2 1 1 xsd:double
