Dataset description: 2017-001-FA

Ultra-short baseline - navigation points and tracklines for Applied Acoustics EasyTrack Nexus 2 USBL data collected for ROV Global Explorer during USGS field activity 2017-001-FA along the U.S. Atlantic continental shelf break and upper continental slope between the Baltimore and Keller Canyons

Comments:

The USBL (ultra-short base line) system calculated the bearing and slant range between the transceiver and remote beacons, as well as depths and positions of the beacons relative to the ship, corrected for pitch, roll, and installation offsets. Ship navigation was supplied by the POS/MV and a Hemisphere GPS receiver.
