    dct:description "Multichannel minisparker and boomer seismic-reflection data were collected by the U.S. Geological Survey in September of 2013 in Port Valdez, Alaska. Data were collected aboard the USGS R/V Alaskan Gyre during field activity G-01-13-GA, using a 500-Joule SIG 2-mille minisparker or an Applied Acoustics triple plated S-Boomer sound source and a 24-channel Goemetrics hydrophone streamer. Sub-bottom acoustic penetration spans several hundreds of meters and is variable by location." ;
