Hard and soft bottom seafloor substrate data and maps for the NOAA Habitat Blueprint West Hawaii Focus Area (WHFA) in the Main Hawaiian Islands. Cell values in the raster datasets reflect whether the seafloor is hard bottom or soft bottom based on an unsupervised classification run using ArcGIS software with the Spatial Analyst extension. The classifications are based on bathymetry, acoustic derivatives and verified using seafloor optical data. The seafloor substrate map and associated data are accessible online via the Pacific Islands Benthic Habiat Mapping Center (PIBHMC) website at www.soest.hawaii.edu/pibhmc. Prepared by the NOAA Coral Reef Ecosystem Program (CREP) and funded by the NOAA Coral Reef Conservation Program (CRCP) and NOAA Habitat Blueprint, the maps include but extend beyond the boundaries of the CRCP-designated West Hawaii priority site. The data were derived in support of CRCP goals to map all U.S. Coral Reef Ecosystems by developing high-resolution benthic maps to characterize priority reefs and associated habitats. This derivative of bathymetry provides a GIS layer that may be used for benthic and essential fish habitat characterization, and for the study of geologic features. By combining the dataset with bathymetry, other derivatives, and in-situ data, they collectively compose benthic habitat maps which are designed to be used to understand and predict benthic habitats for different organisms that inhabit coral reef ecosystems. The hard and soft seafloor map is being used for long-term ecosystem monitoring, to guide future ground-truthing operations and to identify coral-rich environments and can be used in the development of actionable policies, plans and management practices.

This multibeam data may be synthesized with other data including bathymetric LiDAR . Multibeam data collection targets waters ranging from ~20 m to 500 m depths. Bathymetric LiDAR target waters less than 20-m depths. The goal of all data collection is to collect data over the entire seafloor within 0-500 m depths. Accuracy Horizontal positioning system: GPS C/A Horizontal position accuracy: 25 m Range resolution of sonar: varies with depth Raw sounding resolution: varies with depth Vertical accuracy of gridded product ~ 1% of water depth Completeness Report Hard- and soft-bottom substrates were determined for all areas where gridded bathymetry data were available. Some gaps exist in bathymetry coverage due to 1) hazardous conditions that prohibited access for the NOAA vessels, 2) limited time, or 3) limited funding resources. Conceptual Consistency Multibeam bathymetry data were collected by different NOAA vessels using the same collection methods. All multibeam data collected by the Coral Reef Ecosystem Program (CREP) was processed in the same manner. All bathymetry synthesis data used as source data for the products generated for the Main Hawaiian Islands were processed in the same manner by the Hawaii Mapping Research Group. Seafloor imagery was collected by a number of different external partners 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 annually. The Iso Cluster Unsupervised Classification tool in ArcGIS was used to classify the three-band Principle Component Analysis image into two distinct hard vs soft substrate classes. Ground truth optical imagery as well as existing shallow water habitat maps provided by the USGS and NOAA Biogeography Branch were used to validate and correct the hard soft classification. Multibeam bathymetry data collected by NOAA CREP was processed and integrated with existing bathymetry datasets maintained by the University of Hawaii, Hawaii Mapping Research Group (HMRG) to produce a high-resolution (5m) bathymetry synthesis for the entire NOAA Habitat Blueprint West Hawaii Focus Area (WHFA). The Benthic Terrain Modeler in ArcGIS 10.3 was used to derive a series of surface complexity layers using the WHFA bathymetry synthesis. Eight surface complexity layers (mean depth, standard deviation of depth, curvature, plan curvature, profile curvature, slope, slope of slope, and rugosity) and Bathymetric Position Index (BPI) layers for zone and structure were produced. A Principle Component Analysis (PCA) using ENVI 5.3 software was performed on the bathymetry synthesis and eight complexity surface layers to remove highly correlated data by transforming the image into nine principle components. The first three principle components described 99% of the data variability. The complexity surfaces that contributed the most variance were depth, mean depth and rugosity. These three principle components were retained for use in the benthic classification process. The Iso Cluster Unsupervised Classification tool in ArcGIS was used to classify the three-band Principle Component Analysis image into two distinct hard vs soft substrate classes. To verify the accuracy of the automated delineation, the classified optical validation points were overlaid onto the delineated image to confirm or correct the substrate classes. The delineated classifications were manually corrected if they disagreed with the optical validation points. When optical validation points were absent, the USGS and NOAA Biogeography Branch benthic habitat maps were used as validation. 5m Bathymetric data of Kohala coast of Hawaii 2015-09-01 publication Pacific Islands Fisheries Science Center, PIFSC http://www.soest.hawaii.edu/pibhmc/pibhmc_mhi_haw_bathy.htm WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 2012-06-09 2012-06-29 Cochran, S.A., Gibbs, A.E., and Logan, J.B., 2007, Geologic Resource Evaluation of Pu'ukohola Heiau National Historic Site, Hawaii; Part II, Benthic habitat mapping: U.S. Geological Survey Scientific Investigations Report 2006-5254, 20 p. 2006-09-28 publication United States Geological Survey http://pubs.usgs.gov/sir/2006/5256/ WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 2004-04 2004-08 Costa BM and Battista TA (2013) The semi-automated classification of acoustic imagery for characterizing coral reef ecosystems.
