GPR Applications in Cold Climates Samantha Sinclair1*, Seth Campbell1, Zoe Courville1, and Steve Arcone1 Engineer Research and Development Center (ERDC), U.S. Army Cold Regions Research and Engineering Laboratory (CRREL), Hanover, NH *POC, email: samantha.n.sinclair@erdc.dren.mil Glacier and Ice Sheet Research A: 100 MHz profile from the McMurdo Shear Zone to the ice shelf terminus near Scott Base. The inset figure in (A) shows meteoric ice over marine ice. B) Zoom in of the meteoric ice bottom in a 200 MHz profile along the same transect shown in (A), that shows multiple subglacial fractures. Top: Aerial photo showing the Transition Zone located near Scott Base, Antarctica with major features labeled including approximate ice flow directions (arrows). Note the location of the bottom panel denoted by a and a’. Bottom: 100 MHz GPR profile showing folds near the transition zone which are cross cut by the brine horizon.
