The purpose of this data is to support Florida Keys National Marine Sanctuary (FKNMS) benthic habitat map products and research planning efforts. We are providing improved seafloor mapping data products for areas of the FKNMS. They have been incorporated into the FKNMS Digital Atlas, an interactive dataviewer established in 2018 that features a number of mapping products, groundtruthing images and videos. The Sanctuary and partners have been using the dataviewer mapservice for planning, data visualization, and management plan development.
<DIV STYLE="text-align:Left;"><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>This layer is a Principal Components Analysis (PCA) derived from the Multibeam Sonar data from the Multibeam layer - 2018 North Marquesas – presented in this digital atlas. Those data were collected on several small vessels either owned or under contract to eTrac Inc. in 2018. The Geotiff is the results of a principle components analysis using 8 derived complexity surfaces from LiDAR. The surfaces include bathymetry mean, bathymetry standard deviation, curvature, curvature plan, curvature profile, rugosity, slope, and slope of slope 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>
