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 780,000 km² below the 2000s mean
• about 1,460,000 km² below the 1990s mean
• about 1,960,000 km² below the 1980s mean

Unfortunately we couldn’t climb the roofing off the ice. Low tide and the foreshore ice along with the heavy load meant snowmobiles couldn’t get enough purchase to pull it up the hill/bank. #Nunavut #Arctic #CabinLife
The qamutiq being towed down the pass between town and Victor Bay. The second snowmobile is there in case it needs to toe off to brake the heavy load down the hills. #Nunavut #Arctic #CabinLife
This is how we do it. A thread. To get the lengths of roofing metal over to the cabin on the ice we tied to qamutiiq together. Note. This much metal is heavy. #Nunavut #Arctic #CabinLife
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
As we progress into the boreal winter, long-term (declining) trends in sea ice are mostly found in the outer regions of the #Arctic Ocean. The remaining area becomes ice covered.

The #Arctic #permafrost is 1,000 years old. As it thaws, scientists worry what it might unleash
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.'"
#GlobalWarming #ClimateCrisis #MeltingPermafrost #AncientPathogens
@msquebanh And #BigOil wants to release the toxic #tarsands tailings into the Athabasca River that feeds the Mackenzie River Basin that flows through the #NWT to the #Arctic Ocean. And the federal minister and #Alberta #AER are just fine with poisoning us and our #ecosystems downstream.

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 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
@Climatologist49 @ZLabe
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.

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
