More than half of Southern Hudson Bay polar bears under study are still out on the thick Hudson Bay sea ice that’s been giving Canadian Coast Guard icebreakers so much trouble.

As I pointed out a few days ago, most of the ice remaining on Hudson Bay is in the region used by Southern Hudson Bay polar bears. While you wouldn’t know it from the Polar Bears International “Bear Tracker” – which hasn’t been updated since 2 July – on Friday (24 July 2015) Ontario polar bear researcher Martyn Obbard used the PBI website to reveal where his study sample of polar bears are located.
Obbard posted a little essay on PBI’s “Save our sea ice!” website which had, buried near the end, the admission that on 20 July, five out of his nine Southern Hudson Bay females with satellite radio collars were still out on the ice, “far from the Ontario coast.”

“Heavy ice in Hudson Bay derails CCGS Amundsen’s research plans” – just in from the CBC (22 July 2015, via Twitchy). Worst ice in 20 years.
[original caption for the above photo: “The CCGS Pierre Radisson escorts the oil tanker Havelstern to Iqaluit July 17. Tough ice conditions in area have delayed this summer’s annual resupply, and have now derailed the CCGS Amundsen from its carefully planned summer research program.”]
“Worst ice conditions in 20 years force change of plans to icebreaker research program“
That would be 1992 they’re talking about, the cold year that everyone blamed on the eruption of Mt. Pinatubo. Unfortunately, there are no good detailed ice maps from 1992 (see previous post here). What’s the excuse this year?
CCGS Amundsen is an icebreaker that is usually released from duty to serve as an Arctic research vessel in the summer. And who’s on board? GEOTRACES 2015 Arctic Expedition out of the University of British Columbia with a plan to study (in part) global warming caused “ocean acidification.” Their short blog post shows a map without ice and not a hint they see the irony of the situation.
Here’s the ice they’re talking about (from the Canadian Ice Service), with the communities mentioned in the study marked:
