In January-February, a scientific expedition traveled to Antarctica to study its fastest melting glacier, the Thwaites. You can find out more here (includes photos and videos): www.nytimes.com/live/2025/cl... (gift). 🌎

You can follow @zhonggg.bsky.social and Chang Lee's coverage of the trip to the Thwaites Glacier here. This has got to be the most well-covered research cruise ever. 🌊

To go under Thwaites Glacier, the only way is through ⬇️ This intrepid UK-Korean science team are tunnelling 1000m through one of the world's most unstable ice shelves. They'll get daily data showing how warm ocean water is melting Thwaites from below - crucial for predicting sea level rise.

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. Watch the video here: tinyurl.com/526tn8zz

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. 🧵 1/4

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.

Scientists made a stunning discovery beneath an Antarctic ice shelf—thriving life in a world once thought uninhabitable.The breakthrough offers new insights into deep-sea ecosystems and the resilience of life in extreme environments. indianexpress.com/ar...

1.2 million years - have you heard of ice this old?! 🧊 These ice cores were retrieved as part of the Beyond EPICA - Oldest Ice project, which aims to unlock crucial insights into Earth's past climate and atmospheric conditions #ice #climate Read the full story 👇 www.bas.ac.uk/media-post/a...

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-...

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! 🧵 1/5

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 ❄️🐧 1/3

Hot off the press - the latest edition of the BAS Long Read! 🔥📰 Get ready to hear from three Antarctic scientists - Dr Emma Pearce, Dr Liz Thomas, and Dr Dieter Tetzner - about their work drilling for ice cores in Antarctica Grab a coffee, and settle down for a read 👇 www.bas.ac.uk/blogpost/the...

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 ❄️

🔥New paper alert! 🔥🧪❄️🥼 Ever wondered what to consider when drilling through an ice sheet into rock? We take you through how we chose a drill site in West #Antarctica using field observations, samples, radar survey, modelling & satellite imagery. tc.copernicus.org/articles/19/... @bas.ac.uk 🧵1/n

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. www.nature.com/articles/s41...

The Southern Ocean is a critical part of our planet, exerting profound influences over global climate and ecosystems. Great to see some of the leading-order priorities for its research elucidated by Earle, @carlosmoffat.com et al.! 🌊🧪🥼❄️
