This is great, do you have any approximate date for the first releases?

A 3D animation from our last paper. We compared GPR ice thickness data with modelling approaches in two polythermal glaciers in W-Greenland.

Sea surface temperatures are warming across the entire periphery of the #Arctic Ocean in September.

This is especially observed in areas with long-term declines in sea ice concentration, such around the Chukchi and Kara Seas.

Data from NOAA OISSTv2.1. For more info arctic.noaa.gov/report-card/...
Polar stereographic map of sea surface temperature trends for Septembers from 1979 to 2024. Red shading is shown for warming trends, and blue shading is shown for cooling trends. All areas of the ocean are observing warming.

Our new paper compares GPR ice thickness data with models and looks at glacier thermal structures in Greenland, showing that thermal complexity (warm-cold ice) inside these glaciers is higher than expected.

2024 glacier loss in Svalbard was beyond imagination! 😱

- Anomaly of up to 4 SD!
- Amounts to ~61.7 Gt => 1% of the total ice volume
- Comparable to that of the Greenland ice sheet (55 Gt), which is 50 x larger!

... Otherworldly! 🪐

Close up heli view of the former Klein Nesthorn ridge yesterday! 🚁😲

The summit ridge has lost more than 100 m in elevation and its north face ~130 m! 😱

All this mass ended up on the glacier, causing it to break up! 🌊

Already + 100,000 m3 fallen from the Klein Nesthorn N face at ~3200 m asl, and something between 1 to 5 Millions m3 more are 'forecasted'... 😱

That's quite a thing!
Blatten village evacuated 😭

The 'Crumblocene' is definitely a nice time to live! 🏔️🌊

This is horrible. I don't even know what to say. Some of our most key polar data.

"As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported."

Effective May 5, 2025, NOAA’s National Centers for Environmental Information (NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (COGS). As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported. This includes Sea Ice Index, Snow Data Assimilation System (SNODAS) Data Products, Glacier Photograph Collection, U.S. National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format Gridded Monthly Sea Ice Extent and Concentration, 1850 Onward World Glacier Inventory. If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.

The Warming Stripes have now been extended downwards into the ocean and upwards into the stratosphere!

Collaborative paper which tells the story of how the stripes were developed, and discusses their extension across the Earth system, is now available in BAMS: journals.ametsoc.org/view/journal...

It's so sad to see that this incredible dataset, which has redefined how we approach many Arctic-related studies, may not be updated in the future 😞

📢 The final ArcticDEM & REMA release is here - and it might be the last. Funding cuts put vital polar data at risk. Help us rally support: take the survey! 🔗https://z.umn.edu/pgc-dem-survey #PolarScience #SavePolarData

I finally tried Gaussian Splatting using some handheld photos taken inside an ice cave. In just 10 minutes of training-rendering, the results were stunning, impressive! 😁 For now only for visual purposes...

Check out our latest work from the Dolomites. We tried to estimate the mass balance of the remaining Dolomites glaciers since the 1980s using LiDAR, SfM and historical imagery. No surprise: huge mass loss, shrinking area, and increasing debris cover.

Remember the 1990s? ⌚️❄️
Seems so far away from a glaciological point of view! 😱

And the most recent pic here was taken before the recent record-breaking heatwaves which wiped out 10% of Alpine ice in just 2 years! 🔥
