Summary

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 research vessel Hugh [...]

Purpose

This dataset contains 1-minute navigation points, tracklines, and profile images for over 3100 km of Simrad EK80 split-beam echo sounder data collected by the U.S. Geological Survey during the Mid-Atlantic Resource Imaging Experiment (MATRIX; field activity 2018-002-FA). The data were acquired along portions of the U.S. Atlantic margin between Virginia and New Jersey to investigate potential connections between seafloor methane seepage and sub-seafloor gas hydrate dynamics. Images of the water column profile data were generated in order to provide portable and easily viewable alternatives to the Simrad raw versions of the data. This information allows for spatial correlation of the split-beam echo sounder profile images with other geophysical and sample data for investigating water column backscatter in relation to seafloor morphology and stratigraphy in the area.
