Gridded (5 m cell size) multibeam bathymetry collected aboard NOAA Ship Hiialaka'i and R/V AHI. Bathymetry values shallower than 25 m were derived by gauging the relative attenuation of blue and green spectral radiance as a function of depth. A multiple linear regression analysis of linearized blue and green band spectral values against depth determined the variables of y-intercept, blue slope and green slope values. Variables then used in multivariate slope intercept formula to derive depth. Variables were adjusted to improve the statistical accuracy and spatial coverage of the final derived bathymetry product. Digital image processing to derive depths conducted with the ENVI 4.5 software program while data editing and integration was performed using ArcGIS 9.3. This dataset is for the shelf environment of Kingman Reef, Pacific Remote Island Area, USA The data were derived in support of NOAA Coral Reef Conservation Program goals. Goal 1 is to map all U.S. Coral Reef Ecosystems. This data set specifically addresses Objective 1 and 4: to develop high-resolution benthic maps and to characterize priority deep water reefs and associated habitats. This integration of derived bathymetry with multibeam sonar data provides a GIS layer with expanded spatial coverage that may be used for benthic and essential fish habitat characterization, and for the study of geologic features. By combining the dataset with other bathymetry, backscatter, derivatives, and in situ data, they collectively compose benthic habitat maps designed to be used to understand and predict shallow depth (0m to 150m) benthic habitats for organisms that inhabit coral reef ecosystems.

Multiple tools in ArcGIS 9.3 were used for dataset integration and to extract values for the multiple linear regression analysis and subsequent error analyses. The statisitcs program S-Plus was used for the multiple linear regression analysis to provide original variables for depth derivation. The multivariate slope intercept formula used to derive depth was Depth=Yint+(Mblue)(Xblue)+(Mgreen)(Xgreen). Six derived products, five from the image opo_113810_bgrn_0000000 (Kin8100) and one from the image opo_113810_bgrn_0010000 (Kin8101) were integrated to expand spatial coverage. These images were compiled using individual band files (blue, green, red and NIR) that were provided in TIFF format. The original MLR variables for Kin8100 were Yint=46.2868, Mblue=-6.8663, and Mgreen=42.3119. The product derived from these variables (Kin8100_DB) was mosaiced with four additional products derived using reduced blue and green band slope values and increasingly reduced Y-intercept values as follows: Yint=42.2868, Mblue=-0.8663, and Mgreen=36.3119 (Kin8100_DB9), Yint=38.2868, Mblue=-0.8663, and Mgreen=36.3119 (Kin8100_DB10), Yint=34.2868, Mblue=-0.8663, and Mgreen=36.3119 (Kin8100_DB11), Yint=30.2868, Mblue=-0.8663, and Mgreen=36.3119 (Kin8100_DB12). This was done to increase coverage in shallow areas. More information on this integration process is provided in the product error analysis, availble from PIBHMC upon request. The original MLR variables for Kin8101 were Yint=27.3545, Mblue=-3.0138, and Mgreen=27.9633. No other products were derived from this image. The derived bathymetry from each image were in turn mosaiced giving the the data from image Kin8100 priority due to its better statistical accuracy and spatial coverage. This mosaiced derived bathymetry product (Kin_DBall) was then integrated with the multibeam sonar data, with sonar data prioritized over derived data, to create the final product (Kin_DBMB).
