Type: Raster Layer
Geometry Type: null
Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This layer is a Principal Components Analysis (PCA) derived from the Multibeam Sonar data from the Multibeam layer - 2015-2017 Marquesas West – presented in this digital atlas. Those data were collected </SPAN><SPAN>on NOAA RV Nancy Foster between 2015 and 2017 </SPAN><SPAN><SPAN> The Geotiff is the results of a principle components analysis using 8 derived complexity surfaces from LiDAR. The surfaces include</SPAN></SPAN><SPAN><SPAN> bathymetry mean, bathymetry standard deviation, curvature, curvature plan, curvature profile, rugosity, slope, and slope of slope</SPAN></SPAN><SPAN><SPAN> The PCA Geotiff can used to delineate different benthic habitat types using a three band color scale. To-date, these data have not been used to create a benthic habitat map.</SPAN></SPAN></P></DIV></DIV></DIV>
