Multi-Channel Seismic Data from the Chukchi Sea acquired during the Marcus G. Langseth expedition MGL1112 (2011)
This data set was acquired with a LDEO Multi-Channel Seismic system during Marcus G. Langseth expedition MGL1112 conducted in 2011 (Chief Scientist: Dr. Bernard Coakley). These data files are of Text File (ASCII) format and include Ancillary Seismic data that have not been processed. Data were acquired as part of the project(s): Plate Boundaries around the Chukchi Borderland, and funding was provided by NSF grant(s): ARC09-09568.
