The answer is yes. There are islands in the Northwest Passage that some summers are there and some summers they're below water. The erosion you see when you're up there is such that we should be measuring it. There's erosion because the ice is free.
In the old days, winds and storms didn't matter, because going over the ice was like going over land. Now the wave action because of winds and storms is higher, so erosion on the coastline in the Northwest Passage is higher. Coupled with the fact that the permafrost is starting to rise as it melts, that changes the coastline dramatically. So it is important to measure these changes in real time.
