IKONOS estimated depths were produced using rule-based, semi-automated image analysis of high-resolution satellite imagery for nine locations in the Northwestern Hawaiian Islands. For more information about the estimated depth data see the following online link: http://mercury.ornl.gov/metadata/nbii/html/nos/est%5Fdepth%5Fnwhi.html
Specific equipment configurations are documented in metadata from IKONOS Estimated Depths and cruises KM0206. These metadata can be accessed at: http://www.soest.hawaii.edu/pibhmc/cms/cruise-catalog/
