Field Activity 2015-004-FA

Identifier 2015-004-FA
Purpose Acquire high-resolution seismics from shelf-break to base of upper slope or deeper through the part of the mid-Atlantic margin where we have identified over 250 upper slope seeps
Location mid-Atlantic US margin
Summary 30 72-channel profiles of varying lengths between north of Wilmington and south of Norfolk canyons, including dip and strike lines and profiles over deepwater seeps; continuous EK60 *raw files for most of the cruise;
Info derived seismic profiles
Comments Will also deploy EK60 38 kHz transducer on this cruise. 6 kJ sparker, full 72-channel MCS streamer
