Title:
Glacier Bay Habitat polygons Edition: (Volume I, Version 1.0, 2005)
Abstract:
This file is a subset of the original data collected during May 29 - June 6, 2001, by contract with Thales Geosolutions (<http://www.thales-geopacific.com/>) aboard the R/V Davidson as part of a cooperative survey conducted by the U.S. National Park Service and the U.S. Geological Survey (Biological Resources and Coastal and Marine Geology). The instrument was a Reson 8111 multibeam echosounder (<http://reson.com/sb8111.htm>).
