It’s very open drift ice (1-4/10th concentration) but still: Bear Island (Bjørnøya) in the southern Barents Sea was still surrounded by pack ice at 15 May 2020. As far as I can tell from the Norwegian Ice Service archived ice charts, this hasn’t happened since 2003.
And last week, the island was surrounded by heavy drift ice, which hadn’t happened on 8 May since 1977.
For the second time this month, sea ice around Svalbard Norway was the 6th or 7th highest since records began in the late 1960s. Pack ice at the end of April still surrounds Bear Island (Bjørnøya) at the southern end of the archipelago, which is a rare occurrence at this date. These conditions document a recurrent pattern of high ice extent and especially extreme ice thickness in the Barents Sea since last summer.

From 3-7 April this year, sea ice around Svalbard Norway has been the highest since 1988, but only 6th or 7th highest since records began in the 1970s. Pack ice is year surrounds Bear Island (Bjørnøya) at the southern end of the archipelago for the first time since 2009 at this date, and continues the pattern of high extent and thickness of ice in the Barents Sea since last summer.
Arctic sea ice at the middle of winter (January-March) is a measure of what’s to come because winter ice is the set-up for early spring, the time when polar bears do most of their feeding on young seals.
[Mid-winter photos of polar bears are hard to come by, partly because the Arctic is still dark for most hours of the day, it’s still bitterly cold, and scientists don’t venture out to do work on polar bears until the end of March at the earliest]
At 12 February this year, the ice was similar in overall extent to 2013 but higher than 2006.
A polar bear was spotted this year on Bear Island (Bjørnøya) in the southern Barents Sea on 8 March by the crew at the Meteorological Station. The last time these workers had seen a polar bear was 2011 but this year extensive Barents Sea ice literally brought a bear to their doorstep, similar to the way that sea ice brings bears to southern Labrador and Newfoundland in late winter and spring.
After below-average ice cover around Svalbard for most of the winter months of January and February, by early March the ice had expanded so far to the south it reached Bjørnøya. It was the kind of ice that hadn’t been seen in decades and almost immediately, a polar bear was spotted on shore. Given the length of time that the ice surrounding the island persisted, it is likely more bears came ashore but were not seen: the Meteorological Station at the north end of the island is the only place that people live over the winter (see maps below).

Abundant ice in Svalbard, East Greenland and the Labrador Sea is excellent news for the spring feeding season ahead because this is when bears truly need the presence of ice for hunting and mating. As far as I can tell, sea ice has not reached Bear Island, Norway at this time of year since 2010 but this year ice moved down to the island on 3 March and has been there ever since. This may mean we’ll be getting reports of polar bear sightings from the meteorological station there, so stay tuned.
Sea ice extent as of 11 March 2019, from NSIDC Masie:
Much of the ice that was blown out of the Bering Sea early in the month has returned and ice in the Gulf of St. Lawrence on the East Coast of Canada is the highest its been in years, threatening to impede ferry traffic between Nova Scotia and Newfoundland, as it did in 2015 and again in 2017. The fishing season off Newfoundland might also be delayed by the heavy ice, as it was in 2017.
