Continued slow sea ice melt in the Chukchi Sea with extent well above the 1991-2020 median. Nearshore open water extends farther NW along the Chukotka coast than last year, but on the Alaska side, the lack of any notable open water north of Icy Cape is unusual for recent years. #akwx #Arctic #SeaIce

Continued slow sea ice melt in the Chukchi Sea with extent above the 1991-2020 median for summer solstice. Nearshore open water extends farther northwest along the Chukotka coast than last year but on the Alaska side, the lack of any significant open water north of Icy Cape is unusual for recent years. Melt has barely started in Beaufort Sea even in the Mackenzie River delta.

I will not be at #LPS25, Europe's largest ๐Ÿ›ฐ๏ธ Earth Observation conference, in Vienna this week.

But many of my good friends and colleagues will, including those from @osi_saf , #CCI (Climate Change Initiative), and #CIMR (the future satellite in my profile banner). Catch many of them at the #SeaIce session, but also #SoilMoisture and #SMOS15 sessions.

Enjoy the conference, while I enjoy some early vacation in Grenoble ๐Ÿ˜….

A largely cloud free satellite image of the central Northwest Passage shows that the prior melt ponds along the southern route have drained, and that melt ponds have now formed on the northern route through McClure Strait:

Next week, many of us will be at the #ESA Living Planet Symposium #LPS25 in Vienna! You can find us for sure in the #snow session (A.09.11) on Monday and in the #seaice session (A09.09) on Thursday. We are looking forward to this conference and hope to meet some of you there!

๐Ÿšง Access to SSMIS data from the US satellites is becoming less reliable as this satellite program is reaching its end. Data will become scarser with the time until a full stop in 09/2026. Several OSI SAF products are affected.

Sea ice extent in the Chukchi Sea (northwest of the Alaska coast) is well above the 1991-2020 median. Several days of south winds have finally cleared ice from just north of the Bering Strait. Ice is degrading in Kotzebue Sound. Very little ice loss so far in the Beaufort Sea. #akwx #Arctic #SeaIce

It looks as though there will be an early start to the Northwest Passage sailing season this year:

boop beep another job rejection today.

Since winter is coming have a photo of me doing stuff I'm not qualified for and have no experience at doing according to employers now ๐Ÿคท

Having spent 3 years negotiating for time and equipment, here I am doing the first application of a robotic total station to create floe-local drifting coordinate systems and georeference everything on East Antarctic pack ice. Part of the #SIPEX2012 expedition.

#seaice #climate #innovation

A person in a hi viz vest and yellow/black clothing carrying a backpack and looking at a handheld instrument. The person stands in front of a surveying tripod holding a robotic total station. A few boxes are in front of the person, a red box for the total station, yellow box holding a large battery and warming equipment (a hot water bottle), custom made by the person in the photo. The black box holds extra equipment that isn't cold sensitive. On the far left a pole with a GNSS antenna and total station prism is stuck into snow. The foreground and background are white - a foggy day on snow, in the East Antarctic pack ice zone. Photo by Dr. Jan Lieser, subject is Dr. Adam Steer.

Way back in 2022, as the world tried to readjust back to "normal" following COVID - I helped to co-organise a bootcamp with sponsorhop from the @wcrp_climate IASC, @esaclimate and a generous dollop of help from @PolarRES and @dmidk colleagues.
We gathered 10 senior scientist mentors and 22 students in an old torpedo research station (now used by Roskilde University) for 10 days. It was an extremely intense period but the 4th paper produced by this talented group has just come out.
I consider facilitating #EarlyCareerScientists to work on important science problems an extremely rewarding part of my job, and I'm looking forward to the next one already as part of our PISCO project.

In the mean time, go and read this extremely cool work, collecting together a huge number of radiosonde observations going back to the 1950s over the Arctic Ocean and using them to assess how well CMIP6 models represent lower atmosphere.
