Mosaic of gridded multibeam bathymetry and bathymetry derived from multispectral World View-2 satellite imagery of Baker Island, Pacific Remote Island Areas, Central Pacific.
Gridded multibeam bathymetry is integrated with bathymetry derived from multpectral World View-2 satellite data. Gridded (10 m cell size) multibeam bathymetry collected aboard NOAA Ship Hiialaka'i and R/V AHI in 2007, a 224 (68 m) United States National Oceanographic and Atmospheric Administration research ship. Bathymetry values shallower than ~20 m were derived by gauging the reletive attenuation of coastal, blue, green and yellow spectral radiance as a function of depth. A multiple linear regression analysis of coastal, blue, green and yellow band spectral values against depth determined the variables of y-intercept, coastal,blue, green and yellow slope values. Variables then used in multivariate slope intercept formula to derive depth. Digital image processing to derive depths conducted with the ENVI 4.8 software program while data editing and integration was performed using ArcGIS 10.1 This data set is for the shelf environment of Baker Island.

Bathymetric data derived from a multipectral World View-2 satellite image mosaiced to provide near complete coverage of nearshore terrain around the islands. Bathymetry values shallower than ~20 m were derived by gauging the reletive attenuation of coastal, blue, green and yellow spectral radiance as a function of depth. A multiple linear regression analysis of coastal, blue, green and yellow band spectral values against depth determined the variables of y-intercept, coastal,blue, green and yellow 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.

Gridded bathymetry at 40m resolution surrounding Baker Island, within the Pacific Remote Island Areas - Central Pacific Ocean. Bottom coverage was achieved in depths between 8 and 4700 meters. The Arc ASCII grids and floating point geotifs include multibeam bathymetry data acquired over multiple surveys by the NOAA Ecosystem Sciences Division (as of April 2015). The data were acquired using the Simrad EM300, EM3002D, and Reson 8101 multibeam sonars, with sonar frequencies of 30, 300, and 240 kHz respectively. The grid is mosaiced from data sets acquired in 2006 and 2015.
