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

Cracks in Antarctic 'Doomsday Glacier' ice shelf trigger accelerated destabilization Thwaites Glacier in West Antarctica—often called the "Doomsday Glacier"—is one of the fastest-changing ice–ocean systems on Earth, and its future remains a major uncertainty in global sea-level rise projections.

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

Antarctic glacier's alarming retreat is the fastest ever seen Hektoria glacier on the Antarctic Peninsula retreated 25 kilometres in just 15 months. Its rapid melt could have implications for other glaciers and the rate of sea level rise

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...

Can second the very well fed part 😅

❄️ 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.

🚨 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. 🌊

Continent-wide mapping shows increasing sensitivity of East Antarctica to meltwater ponding - Nature Climate Change This study provides a continent-wide assessment of surface meltwater area in Antarctica between 2006 and 2021, highlighting recent increases in magnitude and variability in East Antarctica, with indic...

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.

Large-scale ice-shelf calving events follow prolonged amplifications in flexure - Nature Geoscience The loss of sea ice enhances swell-induced flexural stress in Antarctic ice shelves before large-scale calving events, according to satellite observations and swell-induced flexural stress modelling.

Interesting new study linking large ice shelf calving events to ⬆️ 🌊 swell-induced flexure.

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.

Change in iceberg calving behavior preceded North Sea ice shelf disintegration during the last deglaciation - Nature Communications Massive tabular icebergs broke off of the UK during the last ice age.

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.
