||"Until recently the only bathymetric data available in the Northwestern Hawaiian Islands (NWHI) came from single-beam charting surveys that were conducted before World War II. In many cases these data were poorly located, and individual banks could be mischarted by several kilometers. Because detailed bathymetric data are required for a variety of management and research purposes, including designation of boundaries for the NWHI Coral Reef Ecosystem Reserve, updating of nautical charts, and for ecosystembased management (e.g., formulating benthic habitat maps and designating essential fish habitat), a consortium of National Oceanic and Atmospheric Administration (NOAA) and University of Hawaii scientists are collaborating to make data collected during mapping expeditions to the NWHI available to the public. Bathymetric data collected through August 2003 are combined to provide a baseline for planning future expeditions and for scientific and management use. Thirty maps span the NWHI from Kure Atoll to western Kauai. IKONOS satellite data provide sufficiently reliable estimated depths only to 16 m for the shallowest banks and islands. LIDAR data (0-30 m) are available at Kure, Midway, and Pearl and Hermes Reef.; mid-depth (15-100 m) multibeam coverage is 80% complete at Midway while all other areas have limited coverage at the 50-m boundary line.; deeper multibeam coverage (100-600+ m) is available from Nihoa to Lisianski Island, and limited multibeam coverage exists in depths greater than 600m. Methods used for registration and processing of the data are described, statistics are presented for the amount of area surveyed to date, and estimates are provided for level of effort to complete surveying in the NWHI."
