MBARI Hawaii Multibeam Survey
In March 1998 the Monterey Bay Aquarium Research Institute (MBARI) completed surveys of selected areas offshore of the Hawaiian Islands of Ni`ihau, Moloka`i, Maui, and the Big Island.
We used the recently developed Simrad EM300 multibeam system to collect bathymetry and backscatter data. We contracted with C&C Technologies to run the system because they had installed the EM300 system on a contracted vessel, the M/V Ocean Alert. The 30 kHz EM300 system, because it is hull-mounted, allowed us to collect georeferenced high-resolution bathymetric and sidescan data at high speeds in water ranging from shelf to abyssal depths.

The swath data have been deposited at the National Geophysical Data Center (NGDC) and are available there for free download. A CD-ROM set that contains images and grids for use with GIS was compiled and is available from MBARI. The MBARI Mapping Team includes Gerry Hatcher, David Caress, Norman Maher, David Clague, and Nancy Barr all from the Monterey Bay Aquarium Research Institute (MBARI). The data were collected by David Clague, Gerry Hatcher, Norman Maher, Jennifer Reynolds (all from MBARI), William Danforth (USGS), and the Mapping crew from C&C Technologies.
