Happy Anniversary everyone! 🧪🌎🦑
Tomorrow, Nov. 12, is the 55th anniversary of Exploding Whale Day. I got to talk about this to my marine bio class today, as I do every year to bring some levity and about the practical nature of how these things happen. 🧪🌎🦑🐋

"Science is being destroyed across many agencies" say federal researchers.

For my latest @nature.com piece, I spoke to 19 different scientists across EPA, NOAA, NIH, NASA, and USGS to document how science is being dismantled across US federal agencies.
Dismantling of US federal agencies will ‘destroy science’
From NASA to the National Institutes of Health, federal agencies conduct research that universities cannot. Agency scientists speak out about the irreplaceable facilities, institutional knowledge and ...

🧪these changes will have deep implications for future generations of scientists, weakening the foundation of science for decades to come.
NSF today released instructions for the next round of applicants to its Graduate Research Fellowship Program. A key group—second-year Ph.D. students—is no longer eligible, and students who are still able to apply will face an unusually narrow timeframe. https://scim.ag/3KlQkQk
‘Completely shattered.’ Changes to NSF’s graduate student fellowship spur outcry
The announcement comes months later than usual, leaving many would-be applicants stranded

Legging it in to the weekend. #antarctica. Dodecalopoda mawsoni from east Antarctica in 2023 (nbp23-03 research cruise). So many legs (12 walking legs!!) yes there’s another “normal” pycno there too! 🧪🌎🇦🇶🦑🐧

A short time-lapse of the clouds going by as we sat at Davis Station in East #Antarctica in 2023 on the RVIB NBP (NBP23-03 research cruise). 🧪🌎🦑🇦🇶🐧

Retiring the only remaining ship in the US arsenal that was dedicated to research in the Southern Ocean....it hurts my soul to know how badly this will impact the science and all (scientists, students, crew, etc) who have worked so hard to advance our knowledge of all things #Antarctica 🧪🌎🦑🇦🇶🐧

Is #fishfriday a thing? Taken in East #Antarctica via our YoYo cam transects in 2023, (NBP23-03)....here are some Antarctic skates (Amblyraja georgiana). 🧪🌎🦑🇦🇶🐧

Don't want to think about politics today. Here's the southern lights over the RVIB NBP (yes, the one currently being decommissioned) taken from Davis Station in East Antarctica (NBP23-03). We had stopped and they were able to capture the greatest photos all night of our ship and the aurora. 🧪🌎🦑🇦🇶🐧

correct....BUT the problem is that eRNA is even more susceptible to contamination at every step. Great idea...but is it practical? single species maybe...but for metabarcoding studies? Other thoughts? 🧪🌎🧬

With all going on in the world...I needed to post something that makes me smile today. Here, a Colossendeis robusta (Colossendeidae; sea spider) and a Gentoo penguin being followed by a chinstrap penguin. Both taken on the RVIB NBP as a part of our research cruises to #Antarctica. 🧪🌎🦑🇦🇶🐧

I've lived and worked on this vessel for many research cruises to #Antarctica since 1998....this is devastating....having to rely on non-dedicated ships to run the US's research interests in the region simply will kill the science and innovation in the Southern Ocean. 🧪
