I'm able to make this animation of how the ocean breathes in and out CO₂ because of data collected by NOAA scientists, data served at NOAA websites, and tools provided by NASA. All are under threat of being dismantled by the Trump administration.

#WeekendReading: Hoogakker (and 67 other people) go into the current state of low-oxygen proxies currently in use in paleoceanography. It's a small book (95 pages), more than a paper, and covers a lot. 🧪⚒️

OSU is hiring! Come work at CEOAS - Open rank faculty position and director of the Oregon State Stable Isotope Laboratory. My network is small on Bluesky, please share widely! Reach out if you have questions about living in Corvallis or about CEOAS specifically.

Last Tuesday, I was set to give a talk on 'climate change in the Northeast' at a retirement home but had to cancel due to hourly job threats.

After nearly two weeks of overwhelming uncertainty, today it happened. I was fired from my dream of working at NOAA. I'm so sorry to everyone also affected.

I’m a federal employee, a research meteorologist at a NOAA lab (OAR-NSSL). I still have my job tonight. Many of my NOAA colleagues and many more of my fellow civil servants don’t. I want to share what people like me do. Instead of doomscrolling, maybe we can learn what civil service looks like.

Delighted to see this paper with collaborators and friends out 🌊

We delve into whether or not remote sensing data can help discriminate amongst the (very) divergent projections of ocean productivity changes from climate models. Should we treat all members of the ensemble equally?

Looking forward to discussing at EGU25!

New starter pack for organisations involved in ocean science in some way. 🌊🧪

I’ll be adding more as they start opening accounts on here.

Let me know which ones I have missed!

Hi folks! Check out this starter pack that we created to find folks in oceanography (including marine microbiology, biogeochemistry, modeling, 'omics, and more). Please reply to this post if you would like to be added to the starter pack. Thanks!
go.bsky.app/KaUvLwp

I'd like to be added, thanks!

So, is anyone interested in and wants to follow people doing marine biogeochemistry?
I might have a starter pack for you!
(also, I blame @malinodalen.bsky.social for this)

Spot anyone not there (maybe you?), say something.

Global impact of benthic denitrification on marine N2 fixation and primary production simulated by a variable-stoichiometry Earth system model Abstract. Nitrogen (N) is a crucial limiting nutrient for phytoplankton growth in the ocean. The main source of bioavailable N in the ocean is delivered by N2-fixing diazotrophs in the surface layer. ...

Congrats to Na Li on her first paper, reminding us not to forget about the benthos when assessing N2 fixation and the global marine nitrogen cycle

When to add a new process to a model – and when not: A marine biogeochemical perspective Models are critical tools for environmental science. They allow us to examine the limits of what we think we know and to project that knowledge into s…

How do YOU decide when to add a new process to a model? This was a fun exercise 🌊https://www.sciencedirect.com/science/article/pii/S0304380024002588

I made a list of marine scientists and oceanographic institutions here for the Oceanography feed. It looks like many people tried Bluesky but then gave up months ago, when it was still quiet. How do we get them back? 🌊
