Geologic characteristics of benthic habitats in Glacier Bay, southeast Alaska
USGS video sled aboard the R/V Alaskan Gyre in Glacier Bay (April 2004). The sled is equipped with forward- and downward-looking video cameras, lights, altimeter, pressure sensor, and pitch and roll sensors. Two down-pointing lasers spaced 20 cm apart provide scale on the seafloor. Position is tracked using ship navigation and an estimate of sled layback.
