@awi 's EM-Bird can measure sea ice thickness from a helicopter: today Janna from our group learned to operate the instrument over the Jade Bight (North Sea). Great weather, but sadly, 0 cm sea ice! 😉
Sea ice extent in the Bering Sea remains close to 1991-2020 median in NSIDC data. Large areas of open water north of the ice edge are normal this time of year. The lack of any significant areas of lower concentration ice in the southern Chukchi Sea is unusual for this point in the Spring. #akwx#Arctic#SeaIce#Climate @Climatologist49@ZLabe
About a two mile strip of shorefast sea ice hanging on at Nome Saturday late afternoon. Beyond that open water, just visible as a thin dark blue line on the Nome CVB webcam looking across Front Street to Norton Sound beyond. 5pm weather 35F (+1.7C), slight sea breeze. #SeaIce#akwx#Alaska
The sea ice melt season in the Arctic is underway and I've got a review of April conditions in a new Alaska and Arctic Climate Newsletter. #akwx#Arctic#SeaIce
Out on the ice with a bigger team today, here's a completely accidental drone shot showing our colleagues from the Greenland Institute of Natural Resources deploying some instruments under the sea ice to measure ocean noise and narwhal populations.
DMI and GINR are collaborating in the EU #HorizonEurope project #ArcticPassion which this works contributes to. I was flying the drone and doing snow work for DMI that will be used in another EU project @polarRES, and it will probably also be used together with ESA satellite data: a nice example of EU projects working together in the #PolarRegions #Greenland#Grønland#Fieldwork#Fieldphoto#Fieldwork2024#Arctic#Snow#SeaIce#DMI#GINR#NCKF
❄️ #Antarctic sea ice extent was 20% below average, the 6th lowest March extent in the record;
❄️ #Arctic sea ice reached its annual maximum in March, marking the highest extent for the month since 2013.

Importance of 1.5°C: The Future of Arctic Sea Ice
"Dr. Alexandra Jahn, University of Colorado Boulder, is the lead author of a recent sea ice paper published in Nature, making clear that only the lowest emissions scenarios will minimize the frequency and length of future sea ice-free periods." https://www.youtube.com/watch?v=rWFWYr9qAWo#Arctic#SeaIce
Sea ice extent as of March 30 in the Bering Sea is almost exactly at the 1991-2020 median and 30 percent higher than the end of March last year in NSIDC data. Ice loss in Kuskokwim and Bristol Bays has been notable in the past week, while in the central Bering Sea, the ice edge has been pushed south a bit by moderate north winds. #akwx#Arctic#SeaIce#Spring2024 @Climatologist49@ZLabe
Being Sea 2024 maximum sea ice extent has been reached in NSIDC data. The max extent almost exactly the same as last year but occurred a month later. The max extent was about 14 percent below the 1991-2020 average and was the latest since 2016. #akwx#Arctic#SeaIce#climate @Climatologist49@ZLabe
It's now a full month since the #Antarctic sea ice minimum this year and still hardly any new ice has formed in the Bellingshausen Sea (lower left in image).
People speculate about when the first "blue ocean event" will occur in the Arctic. In this sector of the Southern Ocean they're already happening. #seaice concentration map from analysis of AMSR2 data by University of Bremen Institute of Environmental Physics.
"Climate models can’t explain 2023’s huge heat anomaly — we could be in uncharted territory
Taking into account all known factors, the planet warmed 0.2 °C more last year than climate scientists expected. More and better data are urgently needed."
Good piece in Nature this week by Gavin Schmidt covers the extremely anomalous temperatures in 2023, well before El Nino got started as well as the loss of #Antarctic#SeaIce and aerosols...
Bering Sea ice extent is now at or very close to the seasonal maximum in NSIDC data. The pack ice edge is not far northeast of St. Paul Island in Pribilof Islands. However, the cold north wind pattern is ending and sustained south to southeast winds and much milder temperatures will spread over the central Bering Sea early this week, pushing the ice edge back north. #akwx#Arctic#SeaIce @Climatologist49@ZLabe
More @osi_saf data spotted out in the wild, Henriette Skourup from @dtuspace showing a combined @esaclimate + OSI - SAF #arctic#SeaIce dataset at the #ChangingArctic conference in Copenhagen today...
Sea ice extent in the Bering Sea as of March 2 is the highest so far this season in NSIDC data. Extent is now higher than this date last year and is typical for the first week in March. The ice edge remains well to the north and northeast of the Pribilof Islands. Reports in recent days from Nome to St. Lawrence Island note poor ice quality with ice appearing thin and weak. #akwx#SeaIce#Climate#Arctic @Climatologist49@ZLabe
The #Antarctic monthly #seaice extent for February 2024 landed among the 3 lowest on record, behind 2023 and very close to 2017.
Nowhere, does sea ice in Feb 2024 seem to fall outside the 30-year mean contour. Except for the A23 #iceberg that is seen northeast of the Antarctic peninsula 🧊😀
Sea ice extent in the Bering Sea remains a bit below the 1991-2020 median in NSIDC data There's been only limited variation in the position of the ice edge the past four weeks due to the frequently changeable winds. Maximum ice extent is typically reached in March, so there's still time for expansion, though with significant storm likely in the western Bering Sea later this week, bringing south to southeast winds, the clock is ticking. #akwx#Arctic#SeaIce
