Benthic habitat maps for Rose Atoll, American Samoa were derived from high resolution, multispectral satellite imagery for 2004, 2006, and 2010. The benthic habitat maps for 2004 were previously generated by NOAA's NCCOS's BioGeography Branch before this project, and they were gathered from NOAA's 2005 publication (NCCOS, 2005). The benthic habitat maps for 2006 and 2010 were generated in this project. Bathymetry (water depth) from 0 to 30 meters was derived from satellite imagery for 2006 and 2010 and validated with multibeam and singlebeam depth data, respectively. Eight geomorphological features of the seafloor (Mean Depth, Standard Deviation of Depth, Slope, Slope of Slope, Rugosity, Curvature, Plan Curvature, and Profile Curvature) were derived from the bathymetry for 2006 and 2010. The geomorphological features were used to perform a Principal Component Analysis (PCA), and the first three Principal Components were used in combination with classified benthic imagery (underwater images of the seafloor) to classify the underwater habitat of the inner lagoon and sloping reef areas of Rose Atoll. The final benthic habitat maps consist of two maps for each of the three years. The first map shows the four dominant cover types that make up the shallow water benthic habitat on Rose Atoll, which are coral, coralline algae, macroalgae, and turf algae. The area in square kilometers of each cover types is provided. The purpose of the first map is to show the most abundant biological cover types in the benthic habitat. The second map show the percentages of the four dominant cover types, which are divided into three bins: 10%-<50% coverage, 50%-<90% coverage, and 90%-100% coverage. The area in square kilometers of each of the cover types is also provided. The purpose of the second map is to examine the smaller changes in the benthic habitat over the three years. The benthic habitat maps were prepared by the Coral Reef Ecosystem Program (CREP) and funded by the Coral Reef Conservation Program (CRCP), in order to determine the feasibility of an automated image analysis program known as CoralNet. These maps were also used in a graduate research project, in order to examine any spatial and temporal changes in the shallow water benthic habitat of Rose Atoll in the years where sufficient spatial data were available. Therefore, the spatial and temporal changes in the shallow water benthic habitat were examined for the years 2004, 2006, and 2010.

The area where the benthic habitat is classified is between 0 to 30 meters, and high-resolution, multispectral satellite imagery was used to fill in any data gaps in the gridded bathymetry derived from multibeam and single beam sonars. Analytical Accuracy Accuracy of multibeam sonar acquired in 2006, which was used to create the 2006 benthic habitat maps: POSITIONAL ACCURACY: Horizontal Positioning System: GPS C/A Horizontal Position Accuracy: 25 meters VERTICAL POSITIONAL ACCURACY: Range Resolution of Sonar: Varies with Depth Raw Resolution of Sonar: Varies with Depth Vertical Accuracy of Gridded Sonar Product: ~ 1% of water depth Vertical Accuracy of Derived Bathymetry Product: 5 meter range Accuracy of single beam sonar acquired in 2012 and 2015, which was used to create the 2010 benthic habitat maps: POSITIONAL ACCURACY: Horizontal Position Accuracy: 6.42 m ± 0.02 (2012), 3.01 m ± 0 (2015) VERTICAL POSITIONAL ACCURACY: Vertical Accuracy of Gridded Sonar Product: 0.02 m ± 0.01 (2012), 0.65 m ± 0.02 (2015) Completeness Report Benthic habitat classifications were determined for the shallow (0 to 30 meters) area of Rose Atoll for all areas visible in the satellite imagery that were used to derive estimated depths. Some data gaps exist in the bathymetry coverage due to features in the satellite imagery that prevent data derivation such as clouds, waves, etc. Conceptual Consistency Estimated depths generated by the Coral Reef Ecosystem Program (CREP) were processed in the same manner using the same methods for the years 2006 and 2010. The bathymetry data used were processed in the same manner by the Pacific Islands Benthic Habitat Mapping Center (PIBHMC). Seafloor imagery was collected by two different NOAA offices using different methods; however, all imagery included in this project for the purposes of ground-truthing was classified by CREP using the same classification scheme by experienced image analysts that are tested and calibrated. To create the benthic habitat maps showing Dominant Cover Types and Percentages of Dominant Cover Types of the shallow water benthic habitat of Rose Atoll for 2006 and 2010, the Maximum Likelihood Supervised Classification (MLC) tool in ArcGIS for Desktop was used to classify the three bands from the Principle Component Analysis (PCA) performed on the eight derived geomorphological features of the seafloor. Bathymetry was derived for the shallow water area (0 to 30 meters) of Rose Atoll from the two multispectral satellite images (2002 and 2009) using ENVI and ArcGIS for Desktop tools. Eight geomorphological features of the seafloor were derived from the derived bathymetry from each of the two satellite images using ArcGIS for Desktop Spatial Analyst and 3D Analyst tools. A Principle Component Analysis (PCA) was performed on the eight derived geomorphological features using the PCA tool in ArcGIS for Desktop. The benthic habitat was classified in ArcGIS for Desktop using the MLC tool, the PCA raster data sets from the 2002 and 2009 satellite images, and the benthic images from towed-diver surveys. otherRestrictions otherRestrictions Access Constraints: None | Use Constraints: None
