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 [...]
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 R. Sharp and resulted in acquisition of more than 2,000 track-line kilometers of multichannel seismic-reflection and colocated split-beam echosounder data, along with wide-angle seismic reflection and refraction data from 63 expendable sonobuoy deployments.
This dataset contains shot and common midpoint (CMP) navigation, processed post-stack profile images, pre-stack and processed post-stack SEG-Y trace data, streamer configuration diagrams, and information logs for 2072 trackline kilometers of multichannel seismic-reflection 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 North Carolina and New Jersey to support mapping of sedimentary and structural features of the sea floor and subsurface and evaluation of geologic hazards and the distribution of methane gas hydrates in below-seafloor sediments.
