So excited to participate in this panel discussing the history and future of #PalaeoPERCS and the amazing, inclusive, and absolutely brilliant international community of early career pal(a)eo scientists! Please join us at 15:00 UTC today for this really important discussion!

Pal(a)eoPERCS @palaeopercs.bsky.social · Jul 19

Next week at #PalaeoPERCS we will be hosting a special seminar celebrating our 5th anniversary. We'll be joined by our past & current committee members. We'd be glad if you could also be a part of this celebration & collective reflection.

3pm UTC today!

Time has gone so unbelievably quickly and I can’t believe it’s been five years since PERCS launched. Feels like yesterday.

Come and join in the fun later today! 💜

What a loss to the community. Markus was one of the first people who treated me as an equal colleague *very* early in my career, and was the PI on the first major grant that I contributed to outside of my PhD. He was always enthusiastic, kind, and exceptionally fun to work with. He'll be missed.

One of my greatest joys is watching the next generation of the @palaeopercs.bsky.social steering committee bring so much to our paleo-ECR community. Check out this incredible panel on science communication they hosted last week. Definitely worth the watch!

A drop from 26% funding to 7% funding success means that those limited people are going to be spending MORE time writing high quality proposals for lower yield. Whats this about "efficiency"?
These screenshots are coming *directly* from the Request to Congress document. Just raw, wanton destruction

We knew it would be bad, but this table, of the impacts of people involved in NSF research straight from the 2026 Request to Congress, is absolutely insane. This is a complete decimation of science and research across all levels. The 66% reduction in funds would yield a >75% reduction in people.

I was part of the scientific ocean drilling community for over a decade before I ever got to sail and collect sediments myself, and while I loved sailing, being on the JR was only a tiny part of my ongoing scientific ocean drilling work. This is the legacy of open science, and we need to protect it.

I'm honored to be part of the Scientific Ocean Drilling story archive. Laura is an incredible interviewer and this archive of stories provides incredible insight into all the very different ways that Scientific Ocean Drilling and its invaluable archives impacts our lives and our planet.

I also validated their feelings: it is a really scary time to be in the US. I would be lying if I said I wasn't scared every day, for my future and those of my friends, colleagues, and communities. But fear can paralyze or it can galvanize. Let it galvanize you. And its always better with friends.

Join a committee at a professional society. Volunteer with a local chapter of a nonprofit. Make art. Contribute to something bigger than yourself. Most of all, don't give up on a better future. If we all work just a little bit towards building the world we want to see, it will help, it has to.

Elizabeth Sibert, PhD @elizabethsibert.bsky.social · May 14

This is how @palaeopercs.bsky.social started: I was feeling isolated and scared for the future in May 2020. I reached out to some friends and they felt similarly. We came together, brainstormed, and a global weekly paleo & ECR-focused seminar series was born. 5 years later its still going strong.

Elizabeth Sibert, PhD @elizabethsibert.bsky.social · May 14

I spoke with an ECR yesterday who was feeling helpless with everything going on, and want to share what I told them: We can choose to build and contribute towards the future we want. Even if ultimately things go awful, we'll have done some good with good people along the way. And that matters.

A *huge* kudos to the current committee at @palaeopercs.bsky.social for continuing this work. This seminar, run by a global team of ECRs for the global community of ECRs across Pal(a)eo-Sciences is one of the things I'm proudest of playing a part in creating. Thank you to all who participate in it.

Elizabeth Sibert, PhD @elizabethsibert.bsky.social · May 12

The world is burning, but I have the honor of giving my "Outgoing Committee Member" talk at Pal(a)eoPERCS tomorrow.
We founded Pal(a)eoPERCS in 2020 to be a place to uplift and support each other in an interdisciplinary global research community. Its even more important today than it was then.

Next week at #PalaeoPERCS we will be joined by Elizabeth Sibert (@elizabethsibert.bsky.social) from the Woods Hole Oceanographic Institution, USA.

HAPPY 75th, NSF!

We’re celebrating this milestone by highlighting some of NSF’s most transformative accomplishments—innovations that have shaped our world and continue to drive progress in health, technology, the environment, and beyond.

Been waiting for this one - Early Miocene was transformative for marine vertebrates (and plankton), and its super cool to see the signal in so many different taxa and using so many wildly different methods.

Humphreys, 1908 was onto something...
"The teeth of fossil fishes are indestructible, and their structure can be almost as clearly demonstrated as those of fishes of the present day, although they were buried in the mud of primeval oceans, in ages so remote as only to be reckoned by eons of time.

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...

I'm seeing a lot of choices being made in the US right now that fall somewhere along the "what is right" vs. "what is easy" continuum. Far too often, we're choosing 'easy'. We need to practice choosing "right", while the choice is still possible. Build those muscles now, before it is too late.

Sending hugs to everyone at NSF (and all the federal agencies). Y'all are the front lines standing up to this insanity and being mowed down, and we all know we're next. Y'all are wonderful humans who gave so much to supporting the scientific enterprise, and we're not going down without a fight.
