Three cruises focused on marine seismic acquisition. Legs MGL0903, MGL0906, and MGL0908 used the seismic source array on the R/V Langseth to acquire deep-penetration seismic reflection data and to provide seismic source signals to be recorded by ocean bottom seismographs (OBS). This is PSEGY data provided by SIO
EarthScope Consortium operates the NSF National Geophysical Facility (NSF NGF).
