This is the second year in a row that freeze-up of Western Hudson Bay ice has come earlier than average. Movement of tagged bears and reports by folks on the ground in WH show some polar bears are starting to hunt seals on the sea ice that’s developing along the shore. It’s unlikely that a strong wind will again blow the newly-formed ice offshore (as happened earlier this year) because the ice is more extensive. It seems polar bear viewing season in Churchill will be ending early this year, just like it did last year.
The 9 November map Andrew Derocher (University of Albera) published on twitter showing tagged and collared polar bear movements on Hudson Bay makes it look like almost no ice is present:
However, the Canadian Ice Service chart for 10 November shows the ice very clearly:
UPDATE 13 November 2018: See more recent ice charts and the latest (November 4-11, week 19) report from the Polar Bear Alert Program in Churchill that confirms the bears are moving offshore.

Ryrkaypiy on the Chukotka coast of Russia is similar to Churchill, Manitoba: both human settlements are of similar size and are close to where polar bears wait for sea ice to form in the fall and where some pregnant females make their maternity dens in preparation for the birth of cubs over the winter (Durner et al. 2018:xxii). Sea ice advances from the west along the Chukotka shore and bears cannot move offshore to resume hunting until the sea ice reaches the village of Ryrkaypiy. According to the Siberian Times, the village is again having problems with local polar bears, as they have for the last several years (including 2013).
“At least twelve polar bears are inside the village, with some of them paying daily visits.
The rest are within three kilometres away.
‘We have to constantly scare the bears away with signal rockets, so far thanks to efforts of the Bear Patrol we manage well’, said acting head of Ryrkaypiy Yevgenia Malakhova.
The large group of bears started to form a month ago when they came close to Cape Kozhevnikov.
‘Now the bears moved close to the village, they also walk back and forth all along the shore line. The animals are irritated because they are ready to leave the area and start hunting in the deep sea, but ice is too thin’, said Malakhova.
All 760 locals are aware of the dangerous situation and take extreme care when moving around the place.”

‘The rules are taking over Inuit tradition and the bears are taking over Inuit. We’re just watching in the distance, afraid of these bears because they’re free to do whatever they want.’ says Brian Aglukark, after two fatal polar bear attacks this summer (CBC, 24 September 2018).
Here’s an excerpt (my bold): continue reading
The Churchill Polar Bear Alert program has been busy in week 6 (Aug.13-19), with 67 occurrences to date: slower than last year but not quite as brisk as 2016. Some bears have already been released from the holding cells of “polar bear jail,” transported outside of Churchill and marked with a green dot to identify them as problem bears to residents of communities further north.
Compare the above to other years below, as welll as weeks 4 and 5. Previous weeks here and here.
Polar bears that have come off the sea ice of Hudson Bay near Churchill, Manitoba in Western Hudson Bay are apparently in a wide variety of conditions, from very fat to skinny. So, not all skinny despite the relatively early breakup of ice in the northwest.
Most of the ice was gone from the NW of Hudson Bay for the week of 23 July 2018 and the graph below shows that this is a new pattern that began in 1997, with only 2009 being an outlier:
Second week of Polar Bear Alert Activity reports (16-22 July) for 2018 and already two bears are in jail, making it the busiest 3rd week in July since 2015:
Additional information is available regarding the fatal mauling of a young Arviat father two weeks ago that may answer the question of why the bear left the Hudson Bay sea ice well before it was necessary. Was it lack of sea ice (blamed on global warming), as biologist Ian Stirling recently insisted — or did natural food attractants lure the bear ashore prematurely?
I would also like to appeal to readers to consider a donation to the Go Fund Me campaign set up to support the widow and children of Aaron Gibbons, who was only 31 years old. So far, there has not been an overwhelming response (less than 1/2 of the modest goal of $5,000 met after two weeks) and that saddens me deeply.
I have contributed myself but each individual can only do so much. Imagine losing your spouse in this most vicious manner (the children witnessed the attack and were the ones that called for help) and think of the challenges of healing your family and keeping it afloat financially. Please see the GO FUND ME page and contribute if you can.
What I’ve learned over the last week is that the polar bear that killed Aaron Gibbons was a big male in poor condition but he was not the only bear onshore at the time. In addition, the Arctic tern nesting colony on Sentry Island was undoubtedly an enticing natural attractant that seems to have encouraged these bears to leave the ice far north of where they might otherwise have come ashore.
UPDATE 20 July 2018: I’ve added the most recent (19 July) map of collared WH polar bear locations on Hudson Bay to the “Condition of the Sea Ice” discussion below. Also, I am pleased to see that the GO FUND ME campaign has now gone above the half-way mark (~$2800.00 as of 2:00 PM Pacific time). My personal thanks to every one who was able to contribute. I hope to see the goal reached within the next few days.
UPDATE 6 September 2018: A news announcement today revealed that the necropsy done on the bear that attacked Aaron Gibbons was an adult male in “fair” condition (thin but not skinny). See my report here and the news story here. And I’m pleased to report that the GoFundMe goal of $5000 for Aaron’s family has been reached: thanks to all PolarBearScience readers for their support.
