Please refer to separate metadata and documentation for these products: Substrate - hard bottom vs. soft bottom - 5 meter grid & 40 meter grid http://www.soest.hawaii.edu/pibhmc/pibhmc_amsamoa_rose_geomorph.htm Shallow-water benthic habitat map http://ccma.nos.noaa.gov/ecosystems/coralreef/us_pac_terr/ This data is for Rose Atoll, Territory of American Samoa, USA. The hard and soft seafloor map previously produced by NOAA Pacific Islands Fisheries Science Center Coral Reef Ecosystem Division is being used to improve sampling techniques for long-term ecosystem monitoring, to guide future ground-truthing operations and to identify coral-rich and species specific environments. By combining this initial product with the shallow-water benthic habitat map produced by NOAA Biogeography Branch, a more complete hard and soft substrate map is produced, which fills in many of the gaps in shallow water.

In both cases, the hard- soft substrate maps were derived using backscatter data, bathymetric variance (at 2 scales) and bathymetric rugosity. Bathymetry and backscatter data were resampled to 5 m grid cell size prior to the classification for shallow water product, and to 40 m grid cell size for the deeper water product. As no seafloor photographs for groundtruthing were available for Rose Atoll, the classification was unsupervised. However, in locations such as French Frigate Shoals, NWHI and Tutuila, American Samoa, where ground truth data were available, the same unsupervised classification method has been found to be a good predictor of substrate type in similar depth ranges and seafloor environments. The shallow-water habitat map produced by NOAA Biogeography Branch was derived by digitally delineating habitat boundaries from georeferenced sonar and orthorectified IKONOS satellite imagery in ArcGIS using the NOAA Habitat Digitizing extension. A first draft map was completed, and areas identified for ground validation. At each ground validation point benthic habitat was characterized by drop camera, free diving or surface observation. A second draft map was produced incorporating the ground validation data.

First polygons were deleted that were not required for this product; the polygons where the Major Reef Structure (M_STRUCT) was either 'Unknown' or 'Other Delineations' were deleted, leaving only polygons where M_STRUCT was 'Coral Reef and Hardbottom' or 'Unconsolidated Sediment.' Polygons covering the lagoon were also deleted as these were covered by the 5-m hard bottom vs. soft bottom product. The polygon shapefile was then converted into an ArcGIS Raster, using the ArcGIS tool, 'Polygon To Raster.'The raster values were checked to ensure that the same value was equivalent to hard substrate as in the CRED hard-soft map, where 'Coral Reef and Hardbottom' was classed as 'hard' and 'Unconsolidated Sediment' was classed as 'soft'. To combine the three maps, the raster layers were mosaiced, using the ArcGIS tool, 'Mosaic To New Raster.' 2013-05-01T00:00:00 otherRestrictions Metadata Access Constraints: None otherRestrictions Metadata Use Constraints: None annually This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
