Seismic Project Information MGL1408
Eastern North American Margin

The GeoPRISMS Eastern North American Margin Community Seismic Experiment involves the collection of an open-access onshore/offshore, active/passive seismic dataset across the Mid-Atlantic continental margin that can be used by the community to tackle a broad range of the science questions stated in the GeoPRISMS Science and Implementation Plans regarding the formation and evolution of rifted margins. The marine active-source part of this program included the acquisition of multichannel seismic reflection and wide-angle reflection/refraction data with the R/V Marcus G. Langseth and the R/V Endeavor (EN546) in September-October 2014. In addition, the airgun shots from the R/V Langseth were recorded by land seismometers as onshore/offshore seismometer (OOS) data and by broadband ocean bottom seismometers (BBOBS), deployed during survey EN537 and recovered during survey EN554. The goal was to collect data to image geological structures beneath the seafloor to learn about the evolution of continental margins and their geohazards.

Onshore/offshore seismometer (OOS) data in conventional SEG-Y format are available at this data center under Available SEG-Y Data - Field below. Broadband ocean bottom seismometer (BBOBS) data in conventional SEG-Y format are available at this data center under Available SEG-Y Data - Processed below. EN537 and EN554 cruise reports are available.
