Check out our International Ocean Discovery Program Data Report from Site U1521 in the Ross Sea, published today! Thanks to my coauthors including A. Shevenell, D. Kulhanek, C. Prunella, and the Exp 374 Scientists for their efforts towards this 🎉 🇦🇶 🚢 publications.iodp.org/proceedings/...

Fantastic work by Aidan Starr, @ianhall.bsky.social & colleagues published in Paleo Paleo yesterday: Subsurface-to-deep C isotope gradients in the Southern Ocean across the MPT! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Another great week at the Climate and Cryosphere Open Science Conference in Wellington. Enjoyed facilitating the Paleoclimate sessions with three other ECRs & got some useful feedback on our work reconstructing oceanographic conditions in the Ross Sea during Pleistocene interglacials 🇦🇶 #NSFFunded

Excited that this paper, led by former PhD student Natalia Varela (based on her dissertation), is now out! We use the occurrence & characteristics of thin, silty turbidites from the Ross Sea to interpret Antarctic Bottom Water outflow since ~3.3 Ma. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

A great week in Wellington at the International Sedimentological Congress where I presented my Miocene record of bottom water changes at ODP Site 1123. I enjoyed learning about all of the research being done using sediments from around Aotearoa and connecting with researchers from NZ and overseas.

INSTANT invites you to a webinar on climate science diplomacy with Dr. James Kirkham (International Cryosphere Climate Initiative). "Climate science diplomacy: What is it? How do YOU do it? And how can we make policymakers care about ice?” 📅 30 January, 12:00 CET scar.org/scar-news/pr...

Data report about bulk sedimentary carbon and nitrogen concentrations and isotopes at IODP Site U1521 in the Ross Sea Antarctica. Led by Felipe Stanchak in collaboration with Exp 374 collegues. See here 👉 publications.iodp.org/proceedings/...

Great study that provides insight into ocean oxygenation during a past warm climate 🤩

Interested in Antarctic Bottom Water formation and AMOC? Workshop being held in Trieste, Italy in May to develop a proposal to understand how circulation has changed through time iodp3.org/new-magellan...

Check out our new paper, led by Molly Patterson at Binghamton University. We show that the marine-based West Antarctic Ice Sheet was sensitive to ice mass loss via ocean-driven melting during the warm Pliocene. 🇦🇶 #NSFFunded @binghamtonu.bsky.social www.nature.com/articles/s41...

We’ve wrapped up drilling at Crary Ice Rise with 228m of sediment core. This is an unprecedented record of the history of the West Antarctic Ice Sheet stretching back millions of years. Initial observations indicate the core includes periods of environmental change during past times of warming.

Great opportunity here to study the Earth system during the often overlooked early Miocene. Application details here!

First NSF grant as a co-PI, very excited about this one! Will be working with colleagues to understand mechanisms of ice sheet growth during a past warm climate through a data-model comparison study. Ready more here! #NSFfunded www.binghamton.edu/news/story/5...

Thanks Ryan!

Congrats to Halima on being awarded a Schlanger Fellowship, so well deserved 👏 #IODPFunded @bingu-earth.bsky.social www.binghamton.edu/news/story/5...

I presented our record of ocean and ice sheet history in the Ross Sea at the 2025 West Antarctic Ice Sheet Workshop held in Coupeville, Washington last week. Loved connecting with researchers from different disciplines including glaciology, oceanography, modeling, and paleoclimate #NSFfunded

A few days left to submit abstracts to the Climate and Cryosphere Open Science Conference (CLIC OSC) held in Wellington, New Zealand, February 9-12. Hope to see you there! 🇦🇶🧊❄️ clic2026.com/abstracts/

Now published in @agu.org Geophysical Research Letters! What happens to marine archaea when they’re hungry? And what does that mean for the TEX₈₆ paleothermometer? Full paper here: doi.org/10.1029/2025... Thanks to my coauthors and mentors for their support — and stay tuned, more is coming!

🇦🇶 INSTANT Travel Grants 🧳 @scarinstant.bsky.social is offering 15 travel grants (up to $1,000) to support ECRs attending the CliC Open Science Conference, 9–12 Feb 2026, and the INSTANT Symposium on 13 Feb. Apply by 31 July 2025. Full details: scar.org/scar-news/pr...

I'm honored to be named as an Ocean Discovery Lecturer this year. If your institution doesn't have much for seminars, but you want to learn about fish and sharks through time or the awesome work by the other lecturers, this is a great chance to bring someone in! usoceandiscovery.org/lecture-seri...

Join the Polar Impact Mentorship Initiative for an hour long panel on "successful" collaborations in polar research! Explore how interdisciplinary teams, communities can work together. Event: Feb 28, 10-11am EST | 3-4pm GMT Register: forms.gle/L4ojd9UjMCti... Learn more: www.polarimpactnetwork.org

Got to crack open some beautiful Antarctic drill cores at Oregon State University’s Marine Geology Repository last week. We will using biomarkers to reconstruct past climate and ice sheet conditions during the Pliocene and Pleistocene 🇦🇶🌡️

Really packing in the gymnastics meets this week- tonight was OSU vs Washington and Alaska at Anchorage. Awesome to see two-time Olympian Jade Carey compete in person! #NCAAGym

Front row seat for my first ever MSU and Big 10 meet! Excited to see the Spartans on vault #NCAAGym

These are fantastic small grants for Early Career Researchers working on Antarctic Science projects. Supervisors - please point your students towards them. A huge range of projects and people have been funded over the years.

Join us tomorrow morning for Day 2 of our session on Southern Ocean and Antarctic paleoclimate #AGU2024 🇦🇶

Fun ocean circulation demonstration in class today! Before it cooled we had a clear bottom water, intermediate water, and surface water 🌊 #oceancirculation #marinescience

I guess I’m doing this bsky thing now. 👋👋👋 Come for the Antarctic paleoglaciology and nerdy lab content, stay for cute pictures of my dog.

👋 New on this platform, making the permanent move from Twitter. I am an oceanographer and geologist and I research how ocean heat influenced Antarctica’s ice sheets during past warm climates 🌡 🌊 🇦🇶
