If so, they’re not saying. This year, with higher-than-average sea ice, we’ve heard much less than usual about the location of tagged Hudson Bay polar bears. Odd, isn’t it?
By this time last year, Polar Bears International rep Alysa McCall had published two reports on the location WHB polar bears tagged by the University of Alberta research team led by Andrew Derocher (Fig. 1 below).
This year, there’s been nothing: not a single PBI mention of WHB breakup. Derocher tweeted a track map on 6 July (2/9 bears ashore), with no updates since, but PBI’s “Bear Tracker” has not been updated since 2 July. Compare this year’s ice cover on Hudson Bay (and elsewhere in Canada) to last year on this date (14 July): quite a difference.
First, the last known location of the U of A’s collared bears, at 6 July 2015:
Sea ice at 14 July 2015 vs. 2014 (Fig. 3): remember that most WHB polar bears usually come ashore about 28 days after the “breakup” point is reached (date of 30% coverage over WHB). Some bears stay on the ice to the bitter end (see Fig. 1, 8 July 2014), which means this year they may not leave the ice until August.
