Description:
Abstract:
ArcInfo GRID format data generated from the 2004 multibeam sonar survey of the Northeastern Channel Islands, CA Region. The data include high- resolution bathymetry.
Purpose:
These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) or other software to display bathymetry data of the Northeastern Channel Islands, CA Region.

Process_Step:
Process_Description:
The multibeam bathymetry and acoustic backscatter data were collected along a continuous swath perpendicular to the direction of the ship using a Kongsberg Simrad EM1002 multibeam sonar system. The data are cleaned of bad navigation and depth readings and corrected for tides to mean lower low water datum using a predictive tide model. The depth readings are gridded into a common grid. The gridded data are converted to ArcInfo GRID format using ArcInfo's ASCIIGRID command.
