Those soccer fields are so busy, real restrooms are important!
But I'm very concerned about new sports facilities even closer to the water, specifically impact of lights on birds -- the north basin is significant winter bird habitat. The soccer lights are so excessive, bright from > half mile away.

A $6.5 million project will also bring long-awaited new permanent restrooms to the Tom Bates Regional Sports Complex.
Pickleball players rejoice: A Berkeley park is adding 6 courts

I presented our latest research on groundwater recharge yesterday to the NSW government water planners for groundwater and coastal syatems. And then led tours to show the team our recharge monitoring sites at Harrie Wood Cave, Yarrangobilly.

Not a fan of the AI-first-and-for-everything approach. But hopefully this initiative will fastrack the DOE Office of Science's integrated research infrastructure efforts, to better connect the globally distributed experiments, data, computing, and people.

Was in a scicomm workshop about video, took me awhile to realize why it was such a turnoff. They kept highlighting movie clips from a clint eastwood western (including someone getting shot!), good fellas, the godfather, wolf of wallstreet, etc.
Just a non-stop selection of violent & offensive men.

Proposal: If you can't attend a meeting, you don't get to send your "AI notetaker". Hosts should start kicking out AI notetakers.

More Greenland photos, featuring some geology. Scoresbysund has some fantastic exposures of columnar basalts, which are ~55 million years old (young for Greenland rocks!) related to flood basalts when the Atlantic was opening up. Fantastical shapes and fall tundra colors

But the story of Allensworth is also a Central Valley groundwater story! Originally, there were multiple flowing wells. Residents formed the Allensworth Rural Water Company to take over from another company. Within a few years, water levels dropped and the wells went dry. #CAwater

Thick fog this morning in the delta.
I feel like I want to make a joke about the second photo, but given the apparent lack of understanding of this current admin, I'll refrain.

Decided to check out Stone Lakes NWR because I had never been but was nearby. Almost eerie lack of birds, and instead I saw this.
Enough with the 🤬 balloons. Stop buying 🤬 balloons.

It was a road trippin' week!
Camped at Salton Sea State Recreation Area. I walked out of my tent to the water & saw a raft of ~1k redheads one morning. Cactus wrens were a great alarm clock. The harbor at the visitor center no longer reaches the shoreline. Saw hundreds of blue-winged teals!

This week I visited Colonel Allensworth State Historic Park, looking for camping. I thought it was military related, but it's not. Founded in 1908, it was the only "town in California founded, financed, and governed by Black Americans".
There's a good audio tour w/photos;

Why the heck does a California STATE public lands kiosk have this federal garbage posted?
And they couldn't even get the name right, it's SS State Recreation Area, not SS State Park.
(Rant, but also genuine question, if anyone knows -- has anyone seen these at other STATE facilities?)

This isn't a great owl photo, but I feel like it really captures how I think of this part of the Imperial Valley -- ag, geothermal, and birds.
Also: It would really be much easier if all birds put out little flags to identify themselves! 🚩

If folks haven't read it, I recommend @annaleen.bsky.social's Stories are Weapons, which is unfortunately more and more relevant during this administration. When I started it, I thought, "yeah yeah, I know this." But each chapter was 🤯; well researched analysis of these tactics, recent & historical.

U.S. Army did bomb Mauna Loa in 1935.
“A total of 20 of the 600-pound bombs were dropped on the lava channels. Fifteen struck the margins, while five others made direct hits, spraying molten rock in all directions.”

New contender for the worst ever disaster TV show! I'm only on S1E1, but it's about Mauna Kea, located in Oahu, erupting. They figured it out from ground observations in the tropical forest ~80 miles north. The complex topography looks similar to the Alps, complicating where to drop the bombs. 🌋
