The team, which Marc led and provided the logistical support for, deployed from Resolute to Nord Greenland before setting up a rustic field camp on the sea ice for six days, during which time we mechanically drilled the ice to measure thickness, measuring snow depth in a grid pattern along the flight lines as well as dragging instruments along the surface that produced the same measurements for comparison to the airborne data.
