Terrace geomorphic feature layer

The terrace geomorphic feature layer represents the spatial extent of the terraces 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). Terraces are ???An isolated (or group of) relatively flat horizontal or gently inclined surface(s), sometimes long and narrow, which is (are) bounded by a steeper ascending slope on one side and by a steeper descending slope on the opposite side??? (IHO, 2008). In this study terraces (broad steps) were calculated based on the gradient of the SRTM30_PLUS model. The SRTM30_PLUS model was masked using the slope feature layer (i.e. terraces we only mapped on the continental slope).
