Hi Amy,
the program ran over the weekend and I have some results. However there's a few problems
to discuss and overcome, perhaps easier in person than via email. Are you at UEA this
afternoon or sometime tomorrow? Please drop by if you are.

Dear Tim,
Here is my list of boundaries for the Canadian populations. The top 5
(Western Hudson, Southern Hudson, Baffin Bay, Davis Strait and Foxe Basin)
are the priority for me. I have also attached a GIS map of the actual
boundaries with my rectangular boundaries on top.
Thanks a lot.
