Sea ice extent in the Bering Sea is highly variable early in the season and depends mostly on the weather and timing of storms. The total extent as of Nov 26 is below the 2006-2022 average. Shallow bays and near river mouths are the first areas to freeze, hence the ice in Norton Sound and near the Yukon River delta. The Gulf of Anadyr usually freezes later than the Alaska coast but near complete absence of #SeaIce this late in the fall is unusual.
Hope you had a nice weekend! Here's your Monday ice update - #Arctic sea ice extent is currently the 5th lowest on record (JAXA data)...
• about 210,000 km² below the 2010s mean

• about 1,460,000 km² below the 1990s mean

Sea ice continues to increase in the seas north and west of Alaska, especially near the coast. Beaufort Sea is now iced over. The overall Chukchi #SeaIce extent as of Nov 25 is almost exactly the same as this time last year and overall the 11th lowest for the date since 1979. Lack of ice on the Russian Bering Sea coast is notable for this point in the season. #akwx #Arctic #Autumn2023 #Climate
It's chilly in Denmark today but there is a massive warm anomaly over #Greenland and the North American part of the #Arctic.
At this time of year, that often means heavy #snow, and sure enough @polarportal 's #weather page shows a long filament of moist air stretching from the mid-latitudes to SW Greenland - surely one of the wetter corners of the planet.- where it is nourishing the #IceSheet.

@nordicnews My favorite part of this article is that there's a word for this long night in Finnish. The article tries to translate into English as "polar night" but even that isn't an everyday phrase (at least not outside the geography affected). Makes me think of the old "how many words does [Northern language] have for snow?" trope. cc my language peeps @wayword and @lingthusiasm #language #arctic #antarctica

Story by Tom Vanden Brook, USA TODAY • November 20, 2023
"WASHINGTON — Deadly pathogens lying dormant in centuries-old Arctic permafrost could become the latest threat from global climate change.
"The potential release of the pathogens has seized the attention of federal government scientists, medical professionals and Pentagon officials. Pathogens – disease-causing organisms – have been trapped for centuries in frozen ground across the Arctic, including vast swaths of #Alaska, #Canada and #Russia. #ClimateChange has had a big impact on the far north, where temperatures have risen at two to four times the rate of the rest of the world.
"In one troubling case, dozens of people were sickened − and thousands of reindeer were killed − when #anthrax spores emerged from the thawing permafrost in an Arctic region of #Siberia and caught local human and animal populations by surprise, researchers say.
"Warming temperatures across the globe could unleash a slew of microbes whose impact on humans, plants and animals is unknown.
“'We know there’s #bacterial, #fungal and #viral #pathogens that are in permafrost,' said Jill Brandenberger, climate security research lead at the Pacific Northwest National Laboratory. 'We know that upon thaw, all three of those classes of pathogens could be released. What we don’t know is how viable it is for them to stay alive and then infect.'"

Sea ice is growing north and west of Alaska in the past week thanks to somewhat cooler weather. However, a change in the weather pattern is already underway that will bring milder air and south winds to Bering and Chukchi Sea regions at least through mid-week. Chukchi Sea #SeaIce extent is currently typical compared to recent years but far below levels that were usual in the late 20th century. #akwx #Arctic #ClimateChange

Sea ice concentration analysis for Wednesday and the same date last year from the National Weather Service Alaska Region Sea Ice Program. Much less ice in the southern Chukchi and Bering Seas currently than this date last year. November 15 and effectively no ice in Kotzebue Sound is especially shocking, even by recent norms. #akwx #Arctic #SeaIce #Climate

Sea ice is gradually expanding in the seas north and west of Alaska. Very unusually for this late in the season, there's still some open water in parts of Beaufort Sea, while Chukchi Sea ice extent remains below the 1991-2020 median in NSIDC data. Nearshore Bering Sea #SeaIce is typical for recent years for the second week in November. Ongoing storminess will likely slow down/reduce ice for a few days in the Chukchi and Bering Seas. #akwx #Arctic #Climate
Sea surface temperatures departure from average around Alaska for the week ending November are almost entirely above normal, with the western Bering Sea especially warm compared to the 1991-2020 average. This will change in the north as #SeaIce forms but still, considerable ocean heat in the southern Chukchi and northern Bering Seas will slow down ice formation. Data courtesy NOAA/PSL/ESRL. #akwx #Arctic #sst
Very large portions of the #Arctic observed temperatures more than 5°C above the 1981-2010 reference period last month! This was especially prominent in areas of missing sea ice.

Happy International Inuit Day.
I saw a post today that the Arctic is best experienced from the comfort of your own home. Seriously this is one of the most magical places on earth and it’s by far best experienced full on, laying on the tundra, or standing at the floe edge, or having tea in a tent with a friend. #Nunavut #Arctic #Inuit #Photography
Seriously, the #Arctic is a wonderful place - but it's also cold, windy, wet and often inconvenient and frustrating. It's definitely best experienced from the comfort of your own home, preferably narrated by David Attenborough - and I can confirm this most sincerely - your view of the Narhwals and the polar bears will be *inifinitely* better on the big (or small) screen than in real life too...
It's early in the Bering Sea ice season but it's off to a slow start, with ice limited to the brackish waters where rivers empty into the ocean. The MASIE multi-sensor, expert human analysis from NSIDC/National Ice Center provides better estimates for low amounts of ice than the satellite products. Early season #SeaIce or the lack there is very important to communities, but this tells us nothing about what the Bering Sea ice extent will be for the winter overall. #akwx #Arctic
October 2023 average temperature departures from 1991-2020 average around the Arctic from ERA5 courtesy of @CopernicusECMWF. Only Scandinavia was significantly colder than normal while nearly all of the Canadian and Russian Asian Arctic were significantly above normal.
For the #Arctic land and ocean north of 60ºN this was the sixth warmest October. For land areas north of 60ºN this October effectively tied with 2021 & 2022 for warmest October on record. #Climate #Autumn2023
