We've never seen anyone so enthusiastic to crush ice – but a team of scientists are studying the cracking of ice, and they’re pretty hyped! ❄️
@newscientist.com spoke to members of the RIFT-TIP project, who are investigating how ice shelf fractures grow.

Liz stands in a walk-in scientific freezer, wearing a warm jacket. She's holding a long ice sample - a narrow stick of ice about a metre long and only a few centimetres wide. It's from a box containing many ice cores. Photo credit: Jamie Oliver, BAS.
We've had a Very Important Ice delivery!
These precious ancient ice core samples from Antarctica are expected to reveal a climate record stretching back more than 1.5 million years 🤯
That's further than we've ever looked back before.

This is almost unbelievable. It's now May and there is still virtually no new sea ice forming in the Bellingshausen Sea (lower left region in image).

Seriously remote work, in Antarctica. The photo is of Halley Research Station, stretching into the distance on a flat white polar landscape, with the label 'Today's Office'
Year-end scramble getting you down? ⏳
Applications for lots of our Antarctic #jobs are closing in the next week. They include vehicles manager at Halley, and Radio Operator and IT Engineer at Rothera Research Station.
These are jobs unlike any other, in one of the most beautiful places on Earth ⬇️

Iceberg A23a pictured from the ISS. The space station is almost as far south as it can reach here (51.5° S, 49.0° W - altitude of 422km). Picture taken on 14 March, so the berg had been grounded at South Georgia for a fortnight by this time.

As polar night ends and sunlight begins to return to Longyearbyen, lets see how the Svalbard seasons progressed last year - from ice-locked fjords in March, through to the first snows of October. Thanks to NASA MODIS via GIBS. Download at full resolution here: aluckman4.wixsite.com/ade-s-world-...

A fieldwork map of the Union Glacier region. Ice thickness is shown in a yellowy-green colour ramp, contours are shown with thin blue lines, and mountain spot heights are given in metres and feet.
A map of the Antarctic Peninsula and West Antarctica, with blue sea and white land. Ice shelves are grey. Various depots are shown on the map as pink crosses, and lines are drawn between these points giving distances.
The last Twin Otter aircraft has just left Rothera which marks the end of the field season, and gives us a chance to look back at the support we have provided over the year. We started with fieldwork and air unit maps!

A map of the recent positions of iceberg A23a from 17th Jan - 3rd March 2025. Bathymetry is shown on the map, with shallow shelf areas indicating where the iceberg is stuck on the seafloor.
A map showing the track of iceberg A23a from calving (breaking off) the Filchner Ice Shelf in 1986, to its most recent position SW of South Georgia. The track is shown with purple dots. Bathymetry is shown with a blue colour ramp.
The world's largest iceberg, A23a, appears to have grounded close to South Georgia. We've been monitoring and mapping this berg for many years now and we're watching closely to see what it might do next! These maps show its route since 1986 and the latest position to the SW of South Georgia ❄️🐧

Fishing for a glacier's secrets
A story of audacious science on an Antarctic ice shelf
Find out why this is the perfect place for an automatic monitoring station to measure ocean temperature, salinity and currents. It's crucial research about potential sea-level rise: are warming waters melting the ice shelf that holds back the glaciers?

A new iceberg, ~30x14 km in size, recently calved from the southern end of the George VI Ice Shelf. It's called A84 and is already making quite an impact, bumping into the Stange Ice Shelf over the weekend! These Copernicus Sentinel-1 images from Polar View show the new berg over the last few days.

Beautiful Sentinel-2 imagery of George VI Ice Shelf with lots of meltwater from yesterday. The patterns that this water produces is like artwork! Fossil Bluff is shown in the second image, and Hodgson Lake shown in the last - a former subglacial lake sealed under ice thick perennial ice ❄️

The Ronne Ice Shelf survived the last interglacial - Nature
Sea salt data from an ice core record show that Antarctica’s Ronne Ice Shelf survived the last interglacial, the last period of enhanced and sustained global warmth about 125,000 years ago.
Important paper in Nature today about collapse of the West Antarctic Ice Sheet. There is a positive isotope anomaly at Skytrain Ice Rise during the last interglacial, consistent with what we found in our high-resolution water-isotope simulations when WAIS collapses.

A page from the report which contains images of the polar ice sheet thickness change and a graph of their sea level contribution
Satellites have transformed our understanding of Earths polar regions, and it's wonderful to see the work of The IMBIE Team recognised by @esa.int as a groundbreaking discovery !

Yesterday, 22/1, another step on the way was reached with the second reaming pass completed to target depth of 125 m, widening the hole to 209 mm. This leaves the third pass to go, which will widen to final diameter of 260 mm down to 120 m. Derryn, Daniel and Chelsea pictured (📷D.Harvie).
