HUGE news: The High Seas Treaty has been ratified and will go into effect next year. This is a historic win for our ocean and planet! 🎉 So, what does this mean? 🤔 ⤵️

Only a few weeks of field season left in New England. At least the leaves are starting to change! 🍁👩🏻‍🔬🧪

Aquarium Friday! Questions of the week: How many species of shark are there? How well can turtles see? If that fish could talk, what would it say? 🦑

USDA Secretary Brooke Rollins is trying to rescind protections for nearly 59 million acres of roadless national forests, opening them to logging, mining, and road construction. That’s 30% of our entire National Forest System. Friday is the last day to submit a comment: www.roadless.org/m/ 🧪

It's a beautiful day to stand with federal employees and concerned citizens fighting to fund NASA! 🌟🌏🔭 Our space program shouldn't face cuts that compromise expert knowledge, scientific advancement, and human safety. Sign the letter of support for our colleagues at NASA 🔗 linked in bio!

Since I’m famous now (i.e. got 17 likes on my post of Thomas the green moray eel), I wanted to remind everyone about my favorite of Thomas’ neighbors — Garnet the spotted gar! She lives at the Aquarium with Gardenia, Garbanzo, Garlic, and Geoff ❤️🐟

I shouldn't be shocked, but I'm still always brought up short to realize how many people think "civility" means "white people speaking in relatively calm voices" no matter what vile shit they say.

Aquarium Friday! Today I was asked how long epaulette sharks can hold their breath, whether stingrays have eyelids, and “Are they okay?” (The last one wasn’t for any reason, and yes, they are.) 🦑🧪🌊

we fired all the GIS specialists and replaced them with AI and it’s FINE

This is an actual exchange from a VP who took an oath to defend the constitution and, as a citizen, is expected to abide by the law. May we one day have accountability for the grotesque lawlessness of this regime.

Aquarium Friday! Got to hang with the elasmobranchs, electric “eel,” and a sand tiger shark jaw. Super nice to have the school year underway and decrease our foot traffic a bit 🌊🦑🧪

Gorgeous day for field work here in New England! 🌊⚒️🧪

No Aquarium Friday this week, but instead I visited the @denvermuseumns.bsky.social and their Jurassic Oceans exhibit! Even got to touch some fossilized gar scales. Those diamond shapes look pretty familiar… 🐟❤️

Hey Folks...You may start seeing social media sites and a website for Climate.us If you see it, follow and share. It is legit and has some amazing, credible people behind it trying to plug leaks in the climate science world. Trust me on this one. More is coming....

From my @1440daily.bsky.social briefing this morning — how rivers work! “A geoscientist explains how rivers ebb, flow, and change shape—impacting their surrounding banks and the communities that rely on them.” 🌊⚒️🧪 youtu.be/elZgu-lhOMs?...

Fieldwork in New Hampshire today! Welcoming the clouds after some scorchers recently. ⚒️🌊🧪

If you happen to be visiting Cape Cod next week, stop by, have a drink, and join Sue Natali and I for a discussion about maps 😎 bit.ly/4fKIBXJ

Today is Day 2 of the public hearing on the EPA’s reconsideration of the 2009 endangerment finding, the key ruling underpinning U.S. greenhouse gas regulations. 🧪 Testimonies start at the top of the hour, and we’re following along: 👇🧵

Wages of unionized workers are 13% higher than their nonunion counterparts. But unions also set a higher pay standard that all workers enjoy. In high-union-density states, median household income is $12,000 higher than in low-union-density states. This is why unions are vital.

Buried in the regime's political takeover letter of the Smithsonian is the worst bit. Unlike exhibits, which are non-destructive towards primary materials, temporary in nature, and reversible, the foundational collections are irreplacable. They want to be able to throw stuff out.

An acrylic painting done in 1982 for an Earth history related 'Cosmic Calendar' that was supposed to be published by a Carl Sagan affiliated business, but the project fell apart leaving a dozen unused paintings. I have mine, including one that is yet unfinished. Here we see a Paleozoic tide pool.

Scientists! @skypeascientist.bsky.social matches scientists with classrooms, libraries, & more for virtual Q&As! It's easy and fun! We are looking for 750 more volunteers by 8/15 If you're down to chat with 1-5 classrooms this semester, sign up here www.skypeascientist.com/sign-up.html

People’s connection to nature has declined by over 60% since 1800. While this is in part due to increasingly built-up neighborhoods, intergenerational transmission emerges as the dominant driver. Parents no longer pass on an “orientation” towards the natural world. ⚒️🧪🔗 www.mdpi.com/2673-4834/6/...

Hey, #addOcean! Sometimes I post photos from my Fridays the New England Aquarium (and I would like to do it more often). I also work on the Clean Water Act here in Boston. Would love to be added to your feed, if I fit! 🦑

France contained its largest wildfire since 1949 yesterday. Officials blame climate change for the heightened wildfire risk. Check out the burn scar in true- and false-color Landsat imagery, as well as burned area data from Copernicus, below 🛰️🌍⚒️🧪 #earthobservations #gischat #geosky

Plastics are plan B for the fossil fuel industry.

Let's go NISAR!!! Successful separation - now we wait on the rest of the deployment over the next week or so. #nisar #isro #nasa science.nasa.gov/blogs/nisar/...

Check out this super cool “map” feature from my @1440daily.bsky.social briefing this morning. The Open Syllabus Galaxy shows the ~1 million most frequently assigned texts in their dataset. #gischat

Another day of showing the gar my Gar Gear™️

“Trump's EPA now says greenhouse gases don't endanger people.” Please remember that these terrible, harmful moves are coming from a few new political appointees — not the rest of us. Civil servants at EPA, NOAA, USGS, NASA, etc. are not your enemies. 🧪💔 🔗 www.npr.org/2025/07/24/n...

Public service is a calling. So is science. They’re attacking the helpers. 🧪

Administrator Lee Zeldin announced today that EPA’s Office of Research and Development is being eliminated. This is only one step of the destruction planned for EPA. Please, please stand up for science, and your neighbors, and everything else under attack right now. 🧪 apnews.com/article/epa-...

We love the Women Advancing River Research webinar series! Today, we’re learning about interdisciplinary collaboration to understand non-perennial streams with @margaretzimmer.bsky.social and @burginam.bsky.social. There are even some beautiful maps for #gischat! 👩🏻‍🔬🌊🧪

I talked to a NOAA colleague yesterday who told me that 75% of the federal employees of his division have left and he’s worried about their ability to get work done even if Congress funds NOAA at some level. The devastation to science will be felt for generations.

What a treat to hear Jack Dangermond shout-out our project, where we use GeoAI to track illegal forest loss, during the #EsriUC2025 plenary today! 🌲🛰️ If anyone has access to the slides or a recording, feel free to send it my way 😉 #gischat

Catastrophic for Earth sciences, too. The Earth Science Division operates 20+ satellites in orbit, provides a ton of freely available data, funds research programs and studies, etc etc etc ⚒️🌎🛰️🧪

Yesterday, Tropical Storm Chantal made landfall with sustained winds of up to 50mph and flash flood warnings across the Carolinas. At the end of July, the DOD will no longer provide satellite weather data used for real-time hurricane forecasting. GOES-East image below. Stand up for science. 🌎🌩️🛰️🧪

Driving food insecurity and competition for resources, climate change can indirectly intensify conflict risks. Cornelia Scholz explains how we can analyse trends in climate and conflict data, and understand the risks. www.bellingcat.com/resources/ho...

America is beautiful, contradictory, unfinished. I am proud of our country even as we constantly strive to make it better, to protect and deepen our democracy, to fulfill its promise for each and every person who calls it home. Happy Independence Day. No Kings in America.

Last week, @standupforscience.bsky.social organized an open letter to EPA Administrator Lee Zeldin. It was sent on Monday. Today, over 100 of my friends and colleagues who signed the letter were placed on leave for voicing their beliefs. 🧪 www.eenews.net/articles/epa...

Since my office isn't able to travel right now, I'm extra grateful to @scgis.bsky.social for making their conference keynotes available to live stream! Plus, I love zoo babies 🐼 #gischat #geosky

Normally I post from Boston, but on this #ShowYourStripes day, I’m representing southern Italy. The Mediterranean region is warming 20% faster than the global average. Extreme droughts and water shortages are already occurring, and by 2050, water demand is projected to double — or even triple! 🔥🌎🫠

do you know how depressing it is to say things like "science is good" and "we should have a democracy" and immediately have to clarify that I'm not speaking in my official government capacity

This would be the largest public lands sell-off in modern U.S. history and it's happening with no hearings, no debate, and no public input. See what public lands would be available for sale: www.wilderness.org/articles/med...

Voting on ratification of the High Seas Treaty, a pledge to establish marine protected areas in international waters, is underway at the United Nations Ocean Conference. Currently, 50 of the necessary 60 nations have voted in favor. 🌊🧪 Track the progress here: highseasalliance.org/treaty-ratif...

We feed you. They hunt us.

I love this. I teach my Field Natural History students (whom I call "naturalists" from day one) that being a naturalist is about noticing, asking questions, and making connections, not memorizing all the things.
