Seismic reflection data of a basal channel and ocean cavity at the ice shelf-grounding line area of Support Force Glacier, Filchner Ice Shelf, Antarctica

Support Force Glacier (SFG) is a large ice stream feeding into the Filchner Ice Shelf. The active seismic survey is recorded at the sheet-shelf transition of SFG. We map the bed while grounded, the ocean cavity around a surface channel at the ice shelf and its counterpart at the base, the basal channel, and the seabed. The survey consists of 5 seismic reflection profiles, 2 along-flow profiles and 3 across-flow profiles.

The 2.42GB seismic data were recorded with a 300 m long streamer consisting of 96 30Hz p-wave sensors. The sample rate is 0.5 ms, record length 3000 ms. The data is single fold, shot spacing is 150 m: line name: profile TC paper: direction: #shots: - 20170501 profile I along-flow 291 shots - 20170502 profile III across-flow 28 shots - 20170503 profile II along-flow 71 shots - 20170504 profile IV across-flow 40 shots - 20170506 profile V across-flow 50 shots

Presented are for each line (20170501 used as example): - The raw shots: 20170501_RAW_SHOTS_EDITS_GEOM.segy - The Kirchhoff migrated and depth converted profiles: 20170501stat_TXmig_Zconv.segy - The shot x,y,z coordinates in longitude, latitude and surface height in meters above sea level (z, WGS84 ellipsoid): 20170501_GPS.txt
