Finally checking in on this account after a 3 month hiatus. I’m back in Hobart for the annual #fsa (fish stock assessment) working group meetings at #CCAMLR! Excited to attend and present a paper on my upcoming voyage, and to meet such wonderful people. Here are some of the amazing women of FSA!

Abandoning Antarctic krill management measure threatens conservation progress (commentary) All along the western Antarctic Peninsula, whales, penguins and seals in their millions depend on krill (Euphausia superba) throughout the year. In the most rapidly warming region on the continent,…

Thanks for sharing!!

👍🏽 Nice profile on @researcherose.bsky.social, who's also a PhD student working with Cassandra Brooks on how Southern Ocean fisheries can be best understood & managed

Conference funding announcement with a background of snow and mountains.

Funding for conferences and travel of polar-related work is open for Summer 2025 to polar early career scientists. Up to $5000 will be awarded, and applications may request up to $900 per person, with an additional $100 available for awardees who organize a PSECCO social event at the conference. ❄️🧊

Sand-sized fossils hold secrets to the history of climate change Foraminifera have lived almost everywhere in the ocean for millions of years. Their fossilised remains hold a record of Earth’s past.

Happy international women’s day! Proud to be on the ship with the @antarctic.bsky.social where over 2/3 of the scientists are women! Today we celebrated with a dance party on the heli-deck!

Earth’s strongest ocean current could slow down by 20% by 2050 in a high emissions future Melting Antarctic ice is releasing cold, fresh water into the ocean, which is projected to cause the slowdown

New research out today with colleagues Bishakhdatta Gayen and Andreas Klocker projects that the world’s strongest current, the Antarctic Circumpolar Current, may slow by 20% by 2050 in a high emissions future. So happy to have this out for the world to read!

Waving goodbye to land for the next 2 months! It’s been a pleasure to explore Hobart but now it’s time for Antarctica! #rsvnuyina #DMV3

'The key question is what's driving the changes we're seeing in the satellite record?': Research voyage heads to Denman Glacier – Australian Antarctic Program (News 2025) The Denman Marine Voyage is about to take 60 scientists from a range of disciplines and universities to study one of East Antarctica's fastest melting glaciers from the sea.

Many years in the making, the first dedicated marine science voyage on board Australian icebreaker RSV Nuyina is almost here. The two-month-long Denman Marine Voyage (DMV) is due to depart Hobart this afternoon.

We wish our researchers, partners and all aboard RSV Nuyina a successful mission south to study changes to the Denman Glacier system from the ocean. #DMV - it's finally here!

Wet lab 2

My first time on the #nuyina! We had our lab induction tours today where we saw the wet lab we’d be working in. The vessel is brand new and has an amazing lab space for some awesome science for #DMV! Can’t wait!!

Arrived in Hobart to the cutest statue! Can’t wait to explore some of Tasmania’s wildlife before I set sail!

As our plane landed in Hobart, Tasmania there was a land acknowledgement included in the flight attendant’s debrief acknowledging the traditional stewards of this land. Meanwhile in the US we are dismantling the little bit of DEI we have left. What a paradox

Excited to begin my first #antarctic expedition! Beginning the long travel to the icy continent! 🩵🇦🇶

If we’re renaming bodies of water based on petty grievances, I propose that this be renamed the Kendrick Lamar passage.

Sometimes as grad students we forgot how much impact our mentorship has. This was from a friend- a fellow student I met in one of my joint undergrad/grad classes last year. Mentorship is crucial for the next generation of students, and I’m so proud of them for getting into grad school!

SICB is the best!! One of the most inclusive conferences I’ve ever been to.

list of banned keywords

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

Please add me! As a ECR in the US this brings me hope that our community will come together to protect diverse voices.

Over 83 signatures from polar scientists standing in solidarity with colleagues in the USA and internationally suffering as efforts to increase EDI are systematically eroded.

Email me if you're a polar scientist who'd like to add their name.
