The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: |
Mosaic of bathymetry derived from multispectral WorldView-2 satellite imagery of Agrihan Island, Territory of Mariana, USA, from 2003-08-26 to 2012-05-03 (NCEI Accession 0126914) |
| Abstract: |
Bathymetric data derived from a multispectral WorldView-2 satellite image mosaicked to provide near complete coverage of nearshore terrain around the islands. Bathymetry values shallower than ~20 m were derived by gauging the relative 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. Digital image processing to derive depths conducted with the ENVI 4.8 software program while data editing and integration was performed using ArcGIS 10. This data set is for the shelf environment of Agrihan Island, Mariana. |
