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 Palmyra Atoll, 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). Due to drastically different water qualities between interior and exterior area of the atoll, two images were split into regions representing areas inside and outside of the atoll. Effectively creating four images that were analyzed seperately. Forty two derived products, nineteen from the image opo_86356_msi_0000000 (Pal35600in: fourteen products, Pal35600out: six products) and Twenty-three from the image opo_86356_msi_0010000 (Pal35601in: fifteen products, Pal35601out: eight products) were integrated to expand spatial coverage. The original MLR variables for Pal35600in were Yint=7.5076, Mblue=-6.0909, and Mgreen=18.8197. The product derived from these variables (Pal35600in_DB) was mosaiced with thirteen additional products derived using increasingly reduced Y-intercept values as follows: Yint=6.5076 (Pal35600in_DB1), Yint=5.5076 (Pal35600in_DB2), Yint=4.5076 (Pal35600in_DB3), Yint=3.5076 (Pal35600in_DB4), Yint=2.5076 (Pal35600in_DB5), Yint=1.5076 (Pal35600in_DB6), Yint=0.5076 (Pal35600in_DB7), Yint=-1.5076 (Pal35600in_DB8), Yint=-2.5076 (Pal35600in_DB9), Yint=-3.5076 (Pal35600in_DB10), Yint=-4.5076 (Pal35600in_DB11), Yint=-5.5076 (Pal35600in_DB12), Yint=-6.5076 (Pal35600in_DB13) and Yint=-7.5076 (Pal35600in_DB14). 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 Pal35600out were Yint=23.5804, Mblue=-1.5047, and Mgreen=16.1530. The product derived from these variables (Pal35600out_DB) was mosaiced with five additional products derived using increasingly reduced Y-intercept values as follows: Yint=19.5804 (Pal35600out_DB4), Yint=15.5804 (Pal35600out_DB8), Yint=11.5804 (Pal35600out_DB12), Yint=7.5804 (Pal35600out_DB16) and Yint=3.5804 (Pal35600out_DB20). 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 Pal35601in were Yint=9.1819, Mblue=-7.8389, and Mgreen=23.5717. The product derived from these variables (Pal35601in_DB) was mosaiced with fourteen additional products derived using increasingly reduced Y-intercept values as follows: Yint=8.1819 (Pal35601in_DB1), Yint=7.1819 (Pal35601in_DB2), Yint=6.1819 (Pal35601in_DB3), Yint=5.1819 (Pal35601in_DB4), Yint=4.1819 (Pal35601in_DB5), Yint=3.1819 (Pal35601in_DB6), Yint=2.1819 (Pal35601in_DB7), Yint=1.1819 (Pal35601in_DB8), Yint=0.1819 (Pal35601in_DB9), Yint=-1.1819 (Pal35601in_DB10), Yint=-2.1819 (Pal35601in_DB11), Yint=-3.1819 (Pal35601in_DB12), Yint=-4.1819 (Pal35601in_DB13), Yint=-5.1819 (Pal35601in_DB14) and Yint=-6.1819 (Pal35601in_DB15). 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 Pal35601out were Yint=30.4352, Mblue=-7.2710, and Mgreen=27.6316. The product derived from these variables (Pal35601out_DB) was mosaiced with seven additional products derived using increasingly reduced Y-intercept values as follows: Yint=26.4352 (Pal35601out_DB4), Yint=22.4352 (Pal35601out_DB8), Yint=18.4352 (Pal35601out_DB12), Yint=14.4352 (Pal35601out_DB16), Yint=10.4352 (Pal35601out_DB20), Yint=6.4352 (Pal35601out_DB24) and Yint=2.4352 (Pal35601out_DB28). The derived bathymetry from each image were in turn mosaiced blending the the concurrent data from image Pal35600out and Pal35601out to minimize seams in the area of overlap. Data from this combined grid was prioritized of that from Pal35600in and data from Pal35601in received the lowest priority. Data with better statistical accuracy was given higher "priority" so that they replaced concurrent data with lowere accuracy during the mosaic process. This mosaiced derived bathymetry product (Pal_DBall) was then resampled to a 5 meter grid and integrated with the multibeam sonar data, with sonar data prioritized over derived data, to create the final product (Pal_DBMB). A detailed description of all processing steps is available at: http://oregonstate.edu/~hogrefek/Cookbook/Cookbook_042108.pdf An error analysis of each derived bathymetry grid used is available upon request. 2009-06-17T00:00:00 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.
