We corresponded a couple of years ago when I was on Mt. Erebus. Sounds like you guys have a lot of work to do in a short time. How close does the open water come to the shore at this time of year? How much is the ice moving now and how do you travel out to the edge to get samples? I will be spending two days in Barrow the first week of June, can you give me any tips about what to look for? Good luck, John
