High-resolution multibeam backscatter data - northern Channel Islands region, southern California.

Dataset Identification:

Resource Abstract:
description: This data release presents data for 5-m resolution acoustic-backscatter data of the northern Channel Islands region, southern California. The raster data files are included in "USGS_NChannelIslands_NorthArea_Backscatter_5m.zip" and "USGS_NChannelIslands_SouthArea_Backscatter_5m.zip," which are accessible from https://doi.org/10.5066/F7S46Q1J. In 2004 the U.S. Geological Survey, Pacific Coastal and Marine Science Center collected multibeam-bathymetry and acoustic-backscatter data in the northern Channel Islands region, southern California. The region was mapped aboard the R/V Ewing using a Kongsberg Simrad EM-1002 multibeam echosounder. These data were previously published on-line at http://pubs.usgs.gov/of/2005/1153/. In this data release the data have been reprocessed to a finer spatial resolution (5-m versus 15-m) using more modern processing techniques. Due to the large file sizes the entire survey area is provided as two ASCIIRaster files(USGS_NChannelIslands_NorthArea_Backscatter_5m.zip and USGS_NChannelIslands_SouthArea_Backscatter_5m.zip). A few survey line files in the northern region did not process and are missing from the ASCIIRaster file.; abstract: This data release presents data for 5-m resolution acoustic-backscatter data of the northern Channel Islands region, southern California.
