Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The </SPAN><SPAN>escarpment </SPAN><SPAN>geomorphic feature layer represents the spatial extent of the </SPAN><SPAN>escarpment</SPAN><SPAN>s of the worlds oceans based on interpretation of the SRTM30 plus v7 global bathymetry model. The layer is one of the 25 layers that make up the global seafloor geomorphic features map (Harris et.al. 2014). </SPAN><SPAN>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.</SPAN><SPAN /><SPAN>Escarpments were calculated based on the gradient of the SRTM30_PLUS model.</SPAN></P></DIV></DIV></DIV>
