Summary

Bathymetry and acoustic backscatter data were collected in the San Miguel Passage, Channel Islands, California in August 2007 by the U.S. Geological Survey, Pacific Coastal and Marine Science Center. Data collection was conducted aboard the ship R/V Shearwater as part of the USGS research cruise S-2-07-SC. The San Miguel Passage is within the Channel Islands National Marine Sanctuary, and is the body of water between the two western-most islands of the chain - Santa Rosa and San Miguel Islands. Bathymetry and backscatter data were gridded into 2m-resolution raster and are presented here.
