Amid reports that ice conditions between Newfoundland and southern Labrador are the worst in living memory, another polar bear was reported ashore in the area — just after biologist Andrew Derocher explained to the CBC that bears only come on land when sea ice conditions “fail.”
“Ice too thick for coast guard’s heavy icebreaker” said a 20 April 2017 CBC report on the state of ice in the Strait of Belle Isle. The pack is thick first year ice (four feet thick or more in places) and embedded with icebergs of much older, thicker ice. The ice packed along the northern shore of Newfoundland is hampering fishermen from getting out to sea and is not expected to clear until mid-May.
NASA Worldview shows the extent of the pack ice over northwest Newfoundland and southern Labrador on 19 April 2017 (the Strait of Belle Isle is the bit between the two):
The same day that the above satellite image was taken (19 April), at the north end of the Strait on the Newfoundland side, a polar bear was spotted in a small community northwest of St. Anthony (marked below, “Wildberry Country Lodge” at Parker’s Brook). It’s on the shore of north-facing Pistolet Bay on the Great Northern Peninsula, near the 1000 year old Viking occupation site of L’Anse aux Meadows.
There were no photos of the Parker’s Brook bear but lots of others have been taken this year of almost a dozen seen along Newfoundland shorelines since early March: see my recently updated post, with an updated map of reported sightings. Harp seals are now abundant in the pack ice of southern Davis Strait, providing polar bears with an ample source of food when they need it most and therefore, a strong attractant to the area.
Yet, as I reported yesterday, polar bear specialist Andrew Derocher told the CBC this week that polar bears are almost always “forced” ashore by poor ice conditions. The CBC report included his tweet from 10 April, where he suggested “failed” Newfoundland ice conditions were the cause of multiple bears onshore in Newfoundland this year.
Similar thick ice conditions off northern Newfoundland (perhaps even worse) occurred in 2007, see Twillingate in the spring of 2007 below:
Yet, in 2007 there was not a single polar bear reported onshore in Newfoundland (as far as I am aware) but this year there were almost a dozen. And the photos taken this year show fat, healthy bears – not animals struggling to survive.

Another fat bear onshore in late winter, this time along the Quebec shore of the Gulf of St. Lawrence (22 March 2017) – and this time, one of the witnesses to the sighting took some great photos. Courtesy CBC News (Polar bear makes rare appearance on Quebec’s Lower North Shore 24 March 2017).

Seven polar bears came ashore this week, either passing through or exploring, in Black Tickle, Labrador. It’s not that unusual an occurrence but the take home quote sure is:
“They look really healthy … they have been eating good, these ones have.”
Lucky for them – residents in my novel – EATEN – were not so lucky.
A bear onshore along eastern Hudson Bay late last month was also described as fat.
Quotes from the CBC News report (8 March 2017: “7 polar bears visit stormbound Black Tickle“) below.
Mid-February is the tail end of the winter fast for polar bears. Sea ice is approaching it’s maximum global extent but local maximum extents may vary. Most of the sea ice in Canada is locked in already but two regions still vary at this time of year: the Labrador Sea off Labrador and Newfoundland – where polar bears come to feed on an abundance of newborn harp seals – and the Gulf of St. Lawrence, where polar bears have not been spotted in more than 60 years.
There is almost certainly enough ice for harp seals to give birth in the Gulf this year, if the ice holds (despite some premature hand-wringing by seal biologists). There is more ice in the Gulf and off Newfoundland this year than there was in 2013 (see map below). Continue reading
Sea ice charts for 18 January from NSIDC Masie show exactly as much sea ice in 2017 as there was back in 2006 – 13.4 mkm2.
Could polar bears trump sharks at the theatre? Does the fact that unlike sharks, polar bears make house calls, give it better odds than most?
Take a walk down memory lane and give some thought to what has made films starring big animal predators a hit (or not), like JAWS, THE SHALLOWS, THE BIRDS, GRIZZLY, and a number of others, both classics and bombs. What do these predator attack films tell us (if anything) about the probability of EATEN becoming a terrifying motion picture?

Arctic sea ice is spreading out quickly from its central basin summer refuge – according to this NSIDC Masie ice chart, it has already grown more than 2 mkm2 beyond the annual minimum reached in early September. Ice is already pushing south into the eastern Beaufort and the archipelago of Franz Josef Land in the Barents Sea.
Over the next couple of weeks, shorefast ice will start forming along the coasts of North America and Eurasia (see the first bits off Alaska in the 21 October CIS map below), which will eventually meet the expanding Arctic Basin pack to fill the Basin and Canadian Arctic Archipelago with ice – as it has done for eons.
The evidence from the last decade or so suggests that by the end of October, most of the Arctic north of the 79th parallel (see map below) will be filled with ice – although the Chukchi Sea (north of the Bering Strait) may not fill until sometime in November:
Polar bears usually resume hunting as soon as sea ice conditions permit in the fall, since it’s their last chance to top up their fat reserves before the dark and cold of winter when hunting may become next to impossible.
I’ve copied ice charts from the Masie archives for some previous years at 31 October below.
