🌊 3 year postdoc position in our group here at UMD
Studying interactions of internal waves and deep boundary currents, cross-scale energy fluxes, and Lagrangian observations of topographic wakes.

Thanks for looking!
First runs in the internal wave channel we are constructing! You are seeing the density perturbations via the Schlieren method. The stratification doesn't go up to the free surface and you can see reflections of the internal waves off that interface and the bottom. 🌊
Sigh.
This is the directorate that funds all of the earth, ocean & atmosphere research at NSF.

Alex Pretti from his early days working at the VA
Alex from our time working together, while he was in nursing school. Later, he moved to ICU, working as a nurse to support critically ill Veterans. He had such a great attitude. We’d chat between patients about trying to get in a mountain bike ride together. Will never happen now
Alex Pretti was a colleague at the VA. We hired him to recruit for our trial. He became an ICU nurse- I lover working with him. He was a good kind person who lived to help and these fuckers executed him.
White. Hot. Rage.
The red dot is a baby North Atlantic right whale trying to migrate up the east coast of the United states.
The blue streaks are fast moving shipping vessels entering and leaving New York City harbor.
One collision and the whale is dead.
We need *mandatory* speed limits for these vessels! 🧪🦑🌍
Also important here as noted is the restriction to not cut overhead rates (for some agencies that includes NSF).
I come back from my winter PTO and day one Congress drops the text of a minibus. The dashboard has been updated with the Senate Homeland numbers, and all the info in the CJS-Int-E&W minibus. A House vote is scheduled tomorrow night, and Senate likely later this week.

An artist's drawing of the Ben Franklin submersible. The sub is shown with its side cut open to reveal the interior and technology of the submersible.
A temperature map of the Gulf Stream with the track of the Ben Franklin superimposed on it. Beginning on July 14, 1969 off Florida, ending on August 14 off Nova Scotia.
Wow, why have I never heard of the Ben Franklin mesoscaphe? Like human argo floats, 6 men descended to ∼600m and drifted submerged in the Gulf Stream for 30 days. Along the drift, the crew mapped seafloor properties, biology, noises, and acted as a human occupied CTD analyzing the water column.
Hey, you could be my neighbor!

“Liquid Mirror” is a real technique used for geophysical
fluid dynamics lab experiments!
Although drinking the experiment is not recommended…

Our first direct hit. Oddly our oyster work is the most popular thing we do. Great return on investment for taxpayers funding bay restoration.

In a large conference room full of people, the audience doesn't fit entirely in the frame of a photo. Nearly everyone pictured is standing.
At an @agu.org Town Hall today, @ncar-ucar.bsky.social President Antonio Busalacchi spoke to #AGU25 attendees about what's at stake if NCAR is dismantled.
One attendee asked anyone who uses NCAR research to stand up. Almost everyone in the room stood.

That’s the hall of rejected proposals.
Protester outside fall agu meeting. "Closing NCAR will harm the American public."
One of the few public protests, here at Fall AGU, of Trump Administration actions.
#AGU25
It’s simply not possible to overstate how important NCAR is to US and world science. We need to fight this with everything we’ve got.
This is the only parody song about geophysical fluid dynamics you’ll ever need:

Bit late on this, but yesterday DoD appealed this case about indirect costs to the First Circuit.
I can understand the 'financial/logistical' aspects, but am legitimately curious what the accessibility issue with using Keynote for presentations is. @agu.org
Great article by @zhonggg.bsky.social and Esther Horvath highlighting our EGNOG project on the Northeast Greenland Shelf! www.nytimes.com/2025/12/06/c...
We first note that hand-wringing about the decline in US college enrollments has mistakenly linked such declines to the price of four-year colleges.
But the decline is entirely driven by two-year community colleges (and by for-profit colleges). The four-year sector is the dog that didn't bark.
One of my absolute favorite studies.
Ok, so where do I send my money to purchase one of these?
