A review of a newly-released (22 April 2020, on Earth Day) report commissioned by Canada’s Department of Fisheries and Oceans on the state of the Arctic seas published today in the National Post is a must read. It highlights the report’s emphasis that while the changes going on in our northern seas are indeed marked, they do not necessarily spell doom.
Oddly, polar bears are primarily represented in the report by an overview account of the special case of Western Hudson Bay – an outlier among Canadian subpopulations – that puts special emphasis on the claimed decline in body condition blamed on recent sea ice changes that is not supported by any recent data (Crockford 2020).

The worldwide coronavirus lockdown has meant that the MOSAiC research project, which deliberately froze the icebreaker Polarstern into the Arctic Sea ice last fall, will miss taking scientific measurements during several critical weeks of the melt season (one of the main reasons for the project).
According to a report in the High North News (28 April 2020), at 27 April the Polarstern was between Svalbard and the North Pole (map above). In mid-May, the ship will break out of the ice and proceed south to waters off Svalbard (expected to take about a week) to meet up with two German icebreakers for a high-seas exchange of crew and restock provisions, the only option available after the coronovirus lockdown in Svalbard meant the original plans had to be scuttled. And while waiting for the upcoming research upheaval and breaking free of the ice, the crew of the Polarstern recently reported a visit from a polar bear wandering the ice hunting for seals.

Shot during the 2015 Arctic GEOTRACES expedition aboard the U.S. Coast Guard Cutter Healy. The lack of narrated misinformation makes this video suitable for young children.
This looks to be a different bear than the one I discussed in 2015 here but was undoubtedly taken on the same cruise, because reports at the time (August 2015) said that ‘several’ bears were spotted. Video attributed to ‘Bill Schmoker, PolarTrek teacher 2015’, launched on the Woods Hole Youtube channel 1 April 2020 (no other info provided).

For all of those parents and grandparents struggling to keep school-aged kids occupied and learning while stuck at home during the coronavirus lock-down (and looking ahead to the summer months!), how about using my Polar Bear Facts & Myths book to practice a second language? The book is short (<800 words), the topic is compelling, and the text is simple. As well as the original English, it's also available in French, German, Norwegian, and Dutch – all translated from English by native speakers. Prices have now been reduced on all versions of this title and several others (note it has taken Amazon two weeks to implement these changes).
Purchase two copies (one in your native language, the other in the language the child has been learning), and let them work their way through. This approach makes it easy for kids to tackle this task on their own. For Canadian kids who must take French, this is an excellent way to brush up on their French reading skills while learning about polar bears and the Arctic. Similarly, for a large number of European kids, it’s a chance to practice their English reading skills.
When they are done, you could 1) ask them to find a polar bear picture online and write a caption in their second language; 2) send me a question that the book hasn’t answered and I will respond on this blog, in English! Other links below.

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.
In Svalbard, Norway, it is routine practice to chase polar bears away from settlements with snow machines and helicopters, then tranquilize and relocate them if necessary but in late January this approach led to the death of a young male bear.
Necropsy results released 26 March 2020 revealed that the two year old bear, who had wandered into and around Longyearbyen multiple times in late January, was captured after a prolonged helicopter chase but died enroute as it was flown north to Nordaustlandet (see map below) from circulatory failure due to administering anesthesia after the prolonged stress of being chased.
Video here of the bear being chased out of Longyearbyen by helicopter (photo above is of the New Year’s bear). Longyearbyen has had more problems than usual with polar bears this winter due to the unusually extensive sea ice off the west coast of Svalbard. Polar bears are particularly dangerous in winter and with the abundance of bears in recent years many Arctic communities are at risk with each having to find their own solutions.
In the wee hours of New Years Day 2020 a fat Svalbard polar bear was shot because of persistent visits to downtown Longyearbyen and the public was outraged. A few weeks later a bear attacked a dogsled loaded with tourists. The death of the young bear in late January in the course of removing it (rather than shooting it) is a reminder that tranquilizing a polar bear, especially after a prolonged chase, can be as lethal as shooting it.
The most positive thing that US National Snow and Ice Data Center sea ice experts could say about this year’s winter sea ice maximum was that it wasn’t a record breaker. But it provides ample polar bear habitat when the bears need it most: just before the critical spring feeding season.
In fact, they said: “The 2020 maximum sea ice extent is the eleventh lowest in the 42-year satellite record, but the highest since 2013.” All that winter ice is essential polar bear habitat just before the critical spring feeding season (Crockford 2019, 2020) and it’s one of the reasons that polar bears are thriving.
