Split-beam Echo Sounder and Navigation Data Collected Using a Simrad EK80 Wide Band Tranceiver and ES38-10 Transducer During the Mid-Atlantic Resource Imaging Experiment (MATRIX), USGS Field Activity 2018-002-FA. In summer 2018, the U.S. Geological Survey partnered with the U.S Department of Energy and the Bureau of Ocean Energy Management to conduct the Mid-Atlantic Resources Imaging Experiment (MATRIX) as part of the U.S. Geological Survey Gas Hydrates Project. The field program objectives were to acquire high-resolution 2-dimensional multichannel seismic-reflection and split-beam echosounder data along the U.S Atlantic margin between North Carolina and New Jersey to determine the distribution of methane gas hydrates in below-sea floor sediments and investigate potential connections between gas hydrate dynamics and sea floor methane seepage. MATRIX field work was carried out between August 8 and August 28, 2018 on the...

Images were collected in four separate instances on July 9, August 10, September 1, and October 18, 2019 and cover similar extent. Images were collected to monitor active bluff erosion in the area. The images are presented here in zipped files grouped by month and collection. The images were collected in jpg format and include Exif metadata with GPS date, time, and latitude and longitude, copyright, keywords, and other fields. These files were used in structure-from-motion (SfM) processing to obtain georeferenced 3D data.
