Tracking polar bears – 3 out of 4 S. Beaufort bears on the ice during September 2015

The shore of Alaska is not very important to Southern Beaufort polar bears – most of them stay on the sea ice during the summer and early fall, where they may or may not continue eating. These results of on-going satellite tracking studies by USGS1 confirm results of previous studies.

Beaufort Sea swimming polar bears far from land but not very far from sea ice

Recent accounts of an encounter with a curious polar bear female and her two older cubs in the Beaufort Sea on 16 September give contradictory details about the position of sea ice at the time. The same researcher told one reporter that the ship was 240 km from land, another that it was 240 km from the sea ice, and in another account (that he wrote himself), said the ship had been far from land and sea ice.

University of Victoria (Canada) chemical oceanographer Jay Cullen said on the expedition web site:

“After arriving on station and beginning work the crew noticed three polar bears in the water together which swam around to the ship when our water sampling system was nearly 3500 meters below the surface. The ship was located far from sea ice and land. Indeed, Arctic sea ice extent was the fourth lowest on record this year and there has been speculation that this imposes stress on polar bears which rely on the ice to hunt.”  [my bold]

But the maps below show that at the time of the incident (taken from the expedition web site) and the NSIDC Masie sea ice map for 16 September 2015, the ship [the CCGS Amundsen, acting as a research vessel] was actually quite close to an isolated large patch of sea ice, although further from the edge of the main pack. A patch of sea ice plenty big enough for a polar bear to rest upon – no wonder the bears did not appear stressed.

And the polar bear biologist Cullen consulted (Dr. Andrew Derocher) implied by his response that the bear was indeed far from sea ice. Reminds me of the swimming polar bear off the Hibernia oil platform off Newfoundland March 2015, which turned out to be not far from ice at all. See what you think.

Activist explorer blames more polar bear encounters since 1985 on reduced sea ice

Activist polar explorer Børge Ousland’s told National Geographic that more polar bear encounters on land are due to reduced sea ice –  without any reference to population changes over that time or revealing when or where these observations were made.

Churchill problem polar bear report for 14-20 September 2015

Latest report on problem bears in Churchill, Manitoba, from the town’s Facebook page. See previous post here for map and background. Last week’s report here.

22 polar bears handled to date this year; 15 bears in the holding facility this week. See also last post on Polar Bear Town – a new TV reality show about Churchill polar bears.

Polar Bear Town – Churchill bear stories on TV without gloom and doom propaganda

This was kind of fun – featuring the Churchill polar bear guiding trials and tribulations of PolarBearAlleys Kelsey Eliasson, Dennis Compayre, Brian Ladoon, which premiered Tuesday 22 September in Canada and the US. Supposedly, you can watch online episodes that have aired already (wouldn’t work for me).

Polar Bear Town premiere Sept 22 2015

This is a ‘reality’ TV series, not a documentary. It won’t be to everyone’s taste. But by focusing on independent polar bear guides, you see the bears in their element (and the goings-on in the town) without the constant lectures about global warming and predictions that the bears are all going to die that are, I understand, a feature of Tundra Buggy tours operated by the largest outfit, Frontiers North, due to its partnership with Polar Bears International, a strongly activist organization that many polar bear biologists belong (including Steven Amstrup, Ian Stirling, Andrew Derocher, former WWF employee Geoff York).

So far, anyway – perhaps the lectures are to come? YouTube Trailer below.

UPDATED 29 September 2015: OLN has posted the first episode on Youtube, copied below.

Summer refuge for polar bears in Arctic Basin only 0.3 mkm2 below its possible maximum

At the seasonal minimum 2015, the Arctic Basin was still almost full of sea ice, down only 0.3 mkm2 below the maximum it could ever be.

Remember that spending the summer in the Arctic Basin for most polar bears is just like sitting on the western shore of Hudson Bay – they are all waiting for the refreeze. In either location, they might find something to eat, they might not.

Below are NSIDC MASIE sea ice maps for 10 April 2015 (as big as it gets, basin filled) vs. 17 September 2015: Continue reading

Barents Sea polar bears in excellent condition say Norwegian biologists

Conditions this year (2015) in the Barents Sea were excellent according to the polar bear researchers who work there (Polar bears were as fat as pigs”).

A new survey just completed for a population count showed the bears were are in excellent condition – except the injured ones, of course, which some news organizations are promoting as evidence of harm from global warming-induced sea ice changes because an activist photographer  – not scientists – said so.
