In Spring of 1998 the Monterey Bay Aquarium Research Institute (MBARI) completed surveys of the Northern California and Oregon Margin. Bathymetry and backscatter data were collected using the Simrad EM300 multibeam system on a contracted vessel, the M/V Ocean Alert. We contracted with C&C Technologies to run the system because they had installed the EM300 system. The hull-mounted 30 kHz EM300 system allowed us to collect georeferenced high-resolution bathymetric and sidescan data at high speeds, in water ranging from shelf to abyssal depths.
The data from the survey are presented on these web pages.

Final processing of the data was done using the software package MB-System. These web pages were compiled by the Mapping Team of the Monterey Bay Aquarium Research Institute (MBARI) during the Fall of 2001. The Mapping Team includes Nancy Barr, David Caress, David Clague, Judy Donaldson, Jennifer Paduan, and Brian Schlining. The data were collected by Gerry Hatcher, Norman Maher, and David Clague from MBARI, Jennifer Reynolds from the University of Alaska at Fairbanks, and the mapping crew from C&C Technologies. The Heceta Bank data were collected by Robert Embley and Susan B. Merle from NOAA, with assistance from Jennifer Reynolds, as part of a fisheries study. The EM300 Heceta Bank Survey was funded by the Northwest Fisheries Science Center (National Marine Fisheries Service) and the Oregon Sea Grant Program.References
