Description: <DIV STYLE="text-align:Left;font-size:12pt"><DIV><DIV><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Principle components analysis (PCA) group layer shows areas of different seafloor features in a three band (RGB) image. The PCA used 8 metrics (Depth mean, depth standard deviation, curvature, plan curvature, profile curvature, rugosity, slope, slope of slope) derived from the bathymetry. Each PCA shows the amount of variance within the derived metrics and the results only contain information that uniquely describes the seafloor.</SPAN></SPAN></P></DIV></DIV></DIV>
