These SEG-Y files represent 2761 kilometers of multi-channel seismic data collected by the U.S. Geological Survey during USGS survey 2014-04-FA. These data were collected off the U.S. Seaboard Atlantic as part of the U.S. Extended Continental Shelf project and investigations of tsunami hazards. The ECS objectives of the survey are primarily beyond 200 nm in water depths greater than 4000 m. The 2014 ECS tracks were laid out primarily parallel to the margin to map along-strike variations in sediment thickness and to test the hypothesis that oceanic fracture zones might be loci of thicker sediments
The submarine landslide objectives were along two transects that extend from the headwall of the slide near or on the slope to the distal extent of the run-out on the abyssal plain. The data were intended to image the points of failure, glide planes, relative ages of multiple smaller landslides, and relative volumnes of material displaced and redeposited. Imaging an entire submarine landslide system provides a comprehensive dataset for modeling landslide occurrence and therefore understanding the associated natural hazard.
