The red line is the extension of our economic zone to 200 nautical miles, which is permitted under the United Nations Convention on the Law of the Sea. The white line is actually a guesstimate--an attempt to see where the extension of our continental shelf would lead to. The area between the red and the white will amount to the size of the three prairie provinces once we finish doing the mapping. We are doing that mapping now. We are required to put in a submission by 2013 to simply confirm that our mapping is correct.
