For 2010, a few members of the SASS crew are off to Greenland to experiment with GPR. We will be arriving in Iceland on August 1 and then going on to Greenland. We will leave August 17.
We are doing this with a small NSF EAGER grant from the Arctic Social Science Program. We are not sure if GPR or any other method will work here, but we will experiment with several techniques including EM and magnetics.
Wish us luck.
