I love visuals that bring data to life, so I was very excited when I was asked to create animations for the @uitnorgesarktiske.bsky.social Museum showing the transatlantic scale of humpback whale migrations! This is just a subset of the data I am working with for @bioprotectproject.bsky.social🐋🌍🧪🌊
Happy to see this finally out after several years of hard work - truly an international collab effort! Filling knowledge gaps in the coastal regions of the #Antarctic Ice Sheet is critical for future sea-level rise projections. agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level
Antarctic sea-level contribution is largely controlled by coastal ice-sheet processes, emphasizing the need for detailed observations in this region Data gaps in the ice sheet's coastal zone are ...

wordie -- guess the Antarctic Ice Shelf xylar.github.io/wordie/ I made a game inspired by worldl.io that might appeal to Antarctic researchers and probably no one else.
In Oct 2023, a coffee break at #Cryo2Ice sparked a discussion about the missing pieces in how we model Antarctic ice-shelf collapse. We discuss what progress has been made, and what more is needed, to incorporate diverse collapse triggers: doi.org/10.1038/s41467-026-76772-1
Reconsidering the drivers of ice-shelf collapse - Nature Communications
Antarctic ice shelves face increasing collapse risk as environmental stresses intensify. Long-term weakening, ocean-induced thinning, and loss of stabilizing sea ice can drive disintegration yet are m...

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
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.

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...
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

🚨 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. 💥
Cascading mass loss of Antarctic ice shelves triggered by iceberg collisions
Iceberg calving accounts for about half of Antarctic ice-shelf mass loss. We used satellite imagery to analyze annual ice-shelf front changes and major calving events over eight years from austral sum...
