Happy #PolarPride! Visibility and diversity are so important 🏳️‍🌈✨ I’m proud to be in a field that celebrates the LGBTQ+ community 🌈🧪🐋 #LGBTQinSTEM #DiversityInPolarScience

Happy Polar Pride! This year I'd like to draw attention to @500qs.bsky.social - an awesome campaign for making LGBTQ+ people in STEM more visible! Coincidentally, happy to have played a part making Arctic Pride happen here in Tromsø last week 🏳️‍🌈 #polarpride #LGBTQinSTEM #DiversityInPolarScience

Progressive fracturing in the Thwaites Eastern Ice Shelf has accelerated its destabilization, highlighting a feedback cycle that may influence future Antarctic ice shelf stability and global sea-level rise. doi.org/g99j9j

A fascinating paper in @NatureGeosci that has already sparked considerable debate in the ice community. It's the super-fast withdrawal of Hektoria Glacier on the eastern side of the Antarctic Peninsula in 2022/23. Words by me in @newscientist.com www.newscientist.com/article/2502...

❄️ Calling all glaciology PhD students! ❄️ Applications are now open for next year’s Karthaus Summer School. It’s a great experience and you will be very well fed. Apply here: www.projects.science.uu.nl/iceclimate/k...

Looking forward to Svalbard Science Conference Ny-Ålesund Glaciology workshop this week, where I'll be presenting some new work with @hannahpicton.bsky.social on using remote sensing 🛰 to detect rapid lake drainage, meltwater plumes and links with seasonal glacier dynamics.

The disappearance of the inspiring science adventure film "For Winter" was crushing. Read the article (shorturl.at/02nDR) and... ➡️ Follow and support the amazing Alison Criscitiello ➡️ Tell National Geographic Society this is not OK and recalibrate your relationship with them. ➡️ Tell others.

🚨New paper 🚨@natgeosci.nature.com Greenlandification of Antarctica - comment by me + colleagues @dmidk.bsky.social @eo4cryo.bsky.social + @universityofleeds.bsky.social showing how Antarctica increasingly resembles Greenland- drawing on a mass of work from @esaclimate.bsky.social rdcu.be/eJiqJ

Excited to share our new paper in #AnimalBiotelemetry @springernature.com! We classified killer whale tracks into five movement modes using movement metrics and absolute space use, revealing finer-scale behaviour and insights into how they use space along the Norwegian coast 🐋🛰️🧪 tinyurl.com/y8a3wdmy

Yesterday I gave a talk to ECRs at the @igsoc.bsky.social @igs-egg.bsky.social conference @geogdurham.bsky.social @durhamglaciology.bsky.social on academic networking. My tips and tricks for academic networking for career success are here: www.antarcticglaciers.org/2025/07/stra... Anything to add?

🚨 Our new preprint! *Cascading mass loss of Antarctic ice shelves triggered by iceberg collisions* 🔗 doi.org/10.22541/essoar.175285257.77669558/v1 In 2021, giant icebergs hit Dronning Maud Land ice shelves in #Antarctica, causing a chain reaction of calving & major regional ice-shelf area loss. 💥

🇦🇶 Antarctica’s coastal zone is changing fast & it matters globally. A new #AntarcticRINGS review paper maps what we know, what we don’t & why it matters for sea-level rise. 🌊 Explore fresh insights, a Quantarctica-friendly data package & all figures as downloadable slides: scar.org/scar-news/cr...

Our review of the Antarctic coastal zone is finally available after 3+ years of work with 50+ institutes! We highlight data gaps & future priorities. Preprint here 👇 doi.org/10.22541/ess... #SCAR_RINGS #glaciology

I’m delighted to share that our new paper is now out in @natclimate.nature.com! Our long-term, monthly Antarctic-wide dataset of surface meltwater shows that the East Antarctic Ice Sheet is becoming increasingly prone to surface meltwater ponding.

Interesting new study linking large ice shelf calving events to ⬆️ 🌊 swell-induced flexure. Feat. Voyeykov, a lesser-known East #Antarctic ice shelf that formed one of my PhD chapters! doi.org/10.1038/s41561-025-01713-4 doi.org/10.1017/jog.2021.45

If you're interested in monitoring ice shelf calving front dynamics from @esa.int Sentinel-1, including small-scale frontal ablation, check out my poster today in the Dynamic #Antarctica session (A.09.02) 🛰🧊 #LPS25 #EarthObservation #Cryosphere @npiglaciology.bsky.social

CONGRATULATIONS to our very own @mikebentley.bsky.social who has been awarded an OBE for his services to Antarctic Science! Mike has not only made an outstanding contribution to polar science, he is also a fantastic colleague and we are all delighted for him! ❄️🥳 www.durham.ac.uk/news-events/...

Efforts to limit the global temperature increase to 1.5°C under the Paris Climate Agreement may not go far enough to save the world’s ice sheets, according to a new study led by @geogdurham.bsky.social 👉 www.durham.ac.uk/news-events/...

Skilled animal movement researcher, spatial ecologist, and a talented photographer! 👌 Proud wife-to-be 👩‍❤️‍👩

Thrilled to have won @nature.com 2025 #ScientistAtWork photo competition! 🧪🐳📷 www.nature.com/immersive/d4...

At EGU one of our team @antarcticjenny.bsky.social showed new work on ice-shelf calving front detection from Sentinel-1 🛰 to produce dense time series, revealing huge calving events triggered by iceberg collisions as well as small-scale changes important for field ops and 🚢 unloading.

Large fractures continue to open up at the grounding line of Thwaites Glacier Eastern Ice Shelf. Animation contains @copernicusland.bsky.social #Sentinel-1C data alongside 1A and 1B

Icebergs? The size of a city? 90 miles from the UK? Must be a joke, right? No! Our new paper in @natcomms.nature.com shows massive tabular icebergs broke off the UK in the last ice age before the UK’s ice shelves disintegrated from climate warming. 🧵 www.nature.com/articles/s41... @bas.ac.uk

If you are at #EGU25 next week, drop by my poster in Hall X5 on Monday 28th from 10.45-12.30 to hear about a decade of ice-shelf frontal dynamics in Dronning Maud Land, East Antarctica, including calving events triggered by huge iceberg collisions like this one! 🛰 Image credits: ESA Sentinel-1

An awesome PhD being advertised in Svalbard with @eeror.bsky.social - collecting ground reference data to directly validate satellite radar remote sensing missions! 🛰 ❄️ www.jobbnorge.no/en/available...

I use ICESat-2 for detecting lakes under Antarctica. Local ice surface uplift and subsidence shows us where lakes fill and drain over multiple years. This is important to understand how meltwater moves & its release under ice shelves. An amazing data source from @thenasaearth.bsky.social! 🛰

Today one of our glaciologists Jenny Arthur talked to 2nd grade students at Clover Ridge Elementary in Minnesota about her research, Antarctica from space and life in the Arctic ❄️ 🛰

Today is International Day of Women and Girls in Science! Meet the great women in our team: 👩‍🔬 Synnøve Elvehold, geologist 👩‍💻 Jenny Arthur, glaciologist 👩‍🔬 Katrine Husum, paleoceanographer 👩‍🔬 Elisabeth Isaksson, glaciologist 👩‍💻 Lotte Wendt, glaciologist. #Antarctic #Svalbard #PolarResearch

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.

28 people have added their names already. If you'd like to join us in solidarity and to emphasise the importance of EDI in polar science, then let me know. www.antarcticglaciers.org/2025/02/pola...

Our new paper is out in Nature Geoscience! In an ice-sheet-wide 3-D inventory of crevasses in 2016 and 2021, we find that crevasses are growing in response to ice acceleration on short timescales. @durham-university.bsky.social @byrdpolar.bsky.social @leverhulme.bsky.social

*New evidence of active subglacial lakes under the East #Antarctic Ice Sheet!* We use #ICESat2 to show lakes fill and drain beneath slow-moving ice. Modelling likely meltwater routes suggests lakes discharge meltwater under ice shelves. tiny.cc/wsu7001 @npiglaciology.bsky.social
