MGL1110 Seismic Reflection/Refraction
Seismic:Reflection:MCS
GeoPRISMS:Funded
Processed depth-migrated seismic reflection image profiles across the Aleutian arc from Langseth ALEUT cruise MGL1110 (2011)
These seismic profiles accompany three 2-D line segments from ALEUT cruise MGL1110 that were processed by the USGS to the point of migrated depth and used for figures in the von Heune et al., 2020 G-Cubed publication. The processing was done using ProMAX seismic data processing software on Linux/Redhat hardware. Processing steps and navigation details about these processed lines are given in the accompanying PDF file called "Data_Description_Processing_Flow_Navigation_Notes". These seismic images are in JPEG format. The original seismic data was collected in 2011 with the LDEO Multi-Channel Seismic system during Langseth cruise MGL1110 as part of the ALEUT (Alaska Langseth Experiment to Understand the megaThrust) project. Chief Scientist on the cruise was Donna Shillington. Refer to Cruise MGL1110 for complete acquisition details.
