💡New paper alert!💡 I'm thrilled to share that paper #2 of my PhD is now published in JGR Earth Surface! doi.org/10.1029/2024JF… If you're interested in subglacial lakes, grounding zone dynamics and what happens beneath the margins of the Antarctic ice sheet - read on! 🧵👇

We're recruiting for an ice fracture modeller @BAS_News to help us understand iceberg formation and its influence on sea level rise. 🧊🔍🧑‍💻Advert closes soon - 7th July 2024! Apply here: bas.ciphr-irecruit.com/applicants/vac…

Interested in Antarctic snow layering and the hidden crevasses beneath? Apply for an @EoCdt PhD with @BAS_News, @GeosciencesEd and @DLR_en investigating snow properties using multi-frequency satellite data. Further info: eo-cdt.org/projects/depth… *Apply by 15th Jan '23*

@helenafricker If you mean this one, I think it ran in Adobe Flash which is no longer supported. I have an .exe file of it, if that's any use, but I don't think you'll find it online anymore.

A well-written piece, built from a decade of working together in the NZ mountains and Antarctica.

BAS continues to monitor the #BruntIceShelf in #Antarctica and iceberg A74, which calved earlier this year. #A74 and has moved 30 km in the last 3 days, driven by strong easterly winds. Follow latest progress in this animation from glaciologist Oliver Marsh @ojmarsh

@Benjjwallis @BBCAmos @musthaveitnow @ESA_EO @BAS_News @EoCdt @usnatice Yes that section that's separated to the north is fast sea ice that has been filling in the old Brunt-Stancomb Chasm. BSC has been fairly inactive for a decade or so though, so it's probably at least several metres thick.

@BBCAmos @BAS_News @AdrianLuckham Oops wrong Adrian... sorry @adrian_luckman!

@BBCAmos @BAS_News GPSs have been moving about 8 m/day on average as @AdrianLuckham's maps show, but jumped about 100 metres in an hour between 8am and 9am UK time.

Two of our GPS units on the new iceberg show it is just drifting around with the tides at the moment #A74 #BruntIceShelf @BAS_News

@BBCAmos @BAS_News @AdrianLuckham Yes there are no indications of any knock-on effects at the moment.

@ojmarsh @BAS_News @AdrianLuckham And how are the GPS stations around Halley? Nice and steady, I hope. 😎

@jasoncartwright @BAS_News These ones transmit short burst data packets direct to Cambridge over the Iridium satellite network.
