📢The Past Ocean Oxygenation @pages-ipo.bsky.social Working Group is here! 🚤 We provide insights into the natural variability of seawater oxygen in key periods of the geological record & communicate the science behind oxygen reconstructions 🐳 PO2 is here! pastglobalchanges.org/science/wg/p...

Led by U. LA Lafayette Ph.D. student Gracie Babineaux, we have a new paper out in #EPSL showing how individual foraminiferal δ¹³C analyses of benthic Pyrgo spp. can record short-lived #methane seepage events from the seafloor. 🌊 www.sciencedirect.com/science/arti...

The first planned migration of an entire country due to climate change is happening! Tuvalu, a Pacific island nation, is at risk of being submerged under rising sea level, so it has signed an agreement with Australia to allow 280 Tuvaluans to settle in Australia as permanent residents each year.

Yes. Air conditioners are all powered by electricity, so will get cleaner as we clean up the grid. Heat, by contrast, is mostly fossil-fueled. The real goals, IMO, are ensuring that a) everyone who will need AC in outr heated world, gets it; b) all those ACs are heat pumps (ACs that can also heat).

It's going to be a grand old (like 5-23 My old) time!

🚨New paper just out on environmental upset at the Triassic-Jurassic boundary🚨 Using boron isotopes in fossil oysters, we find a major pulse of ocean acidification and CO2 rise, driving global warming and delaying ecosystem recovery following the end-Triassic mass extinction rdcu.be/ev6XV 🧪🌊⚒️🐚🧵

After a quiet period, we are very happy to finally join Bluesky!🦋. This is the official account of the #Climate Division of the @egu.eu Follow us to stay up to date with Division news, blog posts, Campfires, ways to get involved, and more!😊 We are also on LinkedIn🎉 Come say hello! #EGU

In this paper, we present new global calibrations for the I/Ca proxy for ocean oxygenation, with the first Pacific transect. By comparing data from planktonic foram species that live at different water depths, we gain a better understanding of the proxy and its relationship to O2 #paleoceanography

On my last exam for Marine Geology one of the questions was "what was the most important thing you learned in this class?" and by far the most common answer was some version of "how the record of past climate change can help us understand what's happening now". The people hunger for Paleoceanography

So happy to have been a part of this 📖

A new study has calculated that increasing vegetation in urban areas by 30 per cent could have prevented more than one third of all global heat-related deaths between 2000 to 2019. In total, 1.16 million lives may have been saved with more greenery during this 20-year period. 🌎

Update! PAGES has received confirmation that this does not concern the WDS-Paleo datasets which are curated by a different division within #NCEI.

Nitrogen isotopes are a promising tool to reconstruct symbiosis in planktic foraminifera! Check out our latest paper: bg.copernicus.org/articles/22/...

Watching animals eat is like my biology crack. I don’t need it, I don’t have to do it, I don’t even always like it, but there’s just something about critters noshing on one another that leaves me gobsmacked. And nothing does it like the comb jelly Beroe [Thread 🧵] 📽️ www.youtube.com/watch?v=1xkN...

#ICP15 #abstract and #registration #deadlines - 30th April! www.icp15.com/news/registr... Please submit abstracts - #biogeochemistry , #paleomonsoon , #ocean #climate #dynamics , #paleoclimate #reconstructions and #innovation in #paleoceanography + perspectives talks! #ICP15 #pleanry #speakers 👇🏼.

These are some very unhappy Globigerina bulloides #Forams. I have no idea what is going on here. Are they decalcifying? What are the vacuoles around the specimen? Until this field season, I had never observed this. These were also in the high CO2 "bad water". Has anyone observed this before?

These "Happy Raindrops" are very cute, but this shape is a very persistent myth - no raindrop has ever been that shape. Even at the moment a drop breaks away (see 2nd pic for reality). The boundary between air and water has surface tension & acts like an elastic sheet. Pointy regions don't form.

#ICP15 #awards 120 #ECR #grants. We were able to support a diverse group of applicants from 21 #countries, around 80% of which were #PhD students. Congratulations to all successful applicants 👏🏽👏🏽 Read more 👇🏼 www.icp15.com/news/ecr-gra...

NOAA just announced a long list of datasets that are going away🧪⚒️🌊: www.nesdis.noaa.gov/about/docume... Download what you need asap and send comments to: [email protected]

This is such *chef's kiss* data visualisation. The whole thing is great, but even the first image on its own does the job flawlessly.

The @datarescueproject.org has been working for the past month or so to back up "all" data that might be lost. They have a helpful tracker so that scientists can ensure that their crucial resource doesn't slip through the cracks. #StandUpForScience www.datarescueproject.org/data-rescue-...

The @noaa.gov science seminars continue! All are online and open to the public. Upcoming topics include: Listening to Whales: Using bioacoustics & behavior for conservation Changing Estuaries & Shrimp Monterey Bay’s Iconic Kelp Forests Increasing educational impacts through citizen science

As a postdoc, there's a sad irony to Facebook's people you might know suggestions. I've moved around so much as an academic, I certainly don't know the people my friends know now

🤯

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...

Carleton University and the IAGD are putting on an accessible geology field trip on May 11, 2025. We hope you can join us! Details on the attached flyer. Apply at shorturl.at/DkBOO or contact [email protected] for more information.

I use the chemical composition of foraminifera to tell me about water temperature and oxygen content of past oceans. This article gives a good summary of some of the widespread ways forams are used in science 🧪👩‍🔬

An ongoing passion project of mine at work: making small info placards about women in STEM that hang in our campus biology building. Their stories give me strength & hope especially now when we face 4 years of darkness. Here is the 1st of many I'll be sharing. #WomeninSTEM #academicsky #skystorians

Can we all agree that writing "laboratory" instead of "lab" in our publications feels weird?

With the threats being levied against NOAA, I felt it was time to download all the sediment core and paleoceanography data being stored on NOAA's NCEI, just in case. I have uploaded the script to Github, just in case anyone wants to do the same! 🧪 ⚒️ 🦣 🌊 github.com/evangowan/EJ...

Shameless plug for my article on how to improve accessibility for virtual events, as many facilitators still go out of their way to let participants know how much they want attendees on camera as if simulating eye contact on videoconferencing guarantees engagement! 🤡 web.archive.org/web/20210503...

The AMS is temporarily opening its career services to all who need them, regardless of membership status, and offering dues waivers and meeting registration fee reductions for those impacted by job loss due to changes in the government. Read more: bit.ly/4gRiHAk

Some folks have asked, given recent news, “how do I show my friends/family the impact of NSF?” We have some easy Fact Sheets for you! Here’s a brief thread about this website: new.nsf.gov/about/fact-s... which hosts a ton of useful one-pagers.

Last week I gave a presentation and I assume it went well because afterwards a woman in the back row gave me heart hands. Total stranger. Gen z is delightful

The main DEI page from @agu.org has been modified to take diversity out of the title. Glad to see it's not deleted entirely, but hey AGU, we're watching what you do and remembering the big game you once talked about supporting your diverse membership. Today vs. January

Fantastic bit of good news! Looks like NSF responded to the court order and funded grantees will be able to access already dedicated funds.

Jan 31 evening: Chief Judge John McConnell issues temporary restraining order against any delay in federal funds issued to 22 plaintiff states. Worth a read overall, and the conclusions text is revealing (1/8): (storage.courtlistener.com/recap/gov.us...)

There’s no #scientificevidence supporting the claim that noise from #OSW turbine construction and operation is harming #whales. #WHOI scientists share their expertise with @wcai-npr.bsky.social 📲 Listen: go.whoi.edu/wcai-osw-whales 📸 under NFMS permit 2137

This isn't mine at all, but the Magic School Bus TV cartoon, which inspired untold millennials including myself, originated as an NSF grant 🧪 www.nsf.gov/awardsearch/...

Senior scientists who will be reviewing tenure & promotion files in the future - please remember that the effects of many of these executive orders will disproportionately affect researchers from marginalized groups - often the same folks penalized by COVID-related delays, childcare issues, etc. 🧪

BREAKING: A federal judge has ordered a halt to Donald Trump's sweeping aid freeze, issuing a "brief administrative stay" to preserve the status quo for at least a few days while further litigation plays out.

An LLM "creates textual claims, and then predicts the citations that might be associated with similar text. Obviously, this practice violates all norms of scholarly citation. At best, LLMs gesticulate toward the shoulders of giants." Bender, West, and I contributed to this pro/con piece in PNAS.

Well well well…
