There have been some discussions amongst the five coastal states of the Arctic. As Dave and Dave mentioned, we are talking about the high seas in the central area, so outside the specific economic zones of all the coastal countries.
There have been some discussions. There has been some joint scientific work as well, and we are looking far into the future to when this would be ice free. The discussions are preliminary at this point. There is some studying. I would like to note, however, that it is not a legal vacuum either. The international Convention on the Law of the Sea applies in this area, and so would the UN convention on straddling and highly migratory fish stocks. It's not a complete loophole area, even though it is still covered by ice.
Certainly the U.S. has past experience with fisheries opening internationally before the institutions have caught up with them, which is probably what prompted them to take a leadership role in encouraging other countries to start focusing now on what could be the fishery in the future.
