In my book, phytoplankton are a 10. #sorrynotsorry

Bioluminescent plankton have been seen in Cornwall bbc.co.uk/news/articles/… Noctiluca scintillans is their name (AKA sea sparkle). This is what these tiny, single-celled dinoflagellates look like. @zeiss_micro @BBCCornwall @WMNNews

I've spent years working on this and it really comes down to this: Any single tiny thing you can do to feel like you're helping build a better future is more productive than 10,000 hours of dread.

You're going to want to add that extra blanket to your bed spread tonight & layer up for the commute tomorrow morning as it is going to be quite cold! Prolonged exposure to these temperatures is dangerous to you & your pets so be sure to dress appropriately & limit time outdoors!

❓ A new NOC-led study has put a major question mark over the role a unique group of tiny microscopic plants plays in driving ocean carbon storage. Find out more about the role of Diatoms in the #TwilightZone here ➡️ noc.ac.uk/news/southern-…

Happy 25th birthday to the #Argo program! We’re proud to have been part of making this global ocean observing network a success since 1999! Here’s to the next 25! 🥳

Happy Thanksgiving, tweeps. Enjoying snow here in NY.

I'm so excited to be featured in this excellent article that highlights how important plankton are and the key roles of @osparcomm and the @Plkt_Manifesto in assessing and championing plankton. Where plankton fits in the Earth’s ecosystem irishtimes.com/science/2024/1…

Sober friends: you got this

Extreme defense. The planktonic, zoea larva of a long-clawed porcelain crab (Pisidia longicornis) was in my Plymouth sample this week. The long, javelin-like rostrum and two posterior spines defend against being eaten, the constant danger of planktonic life. @zeiss_micro

Who knew the airport runway in St. Thomas is a hotspot for more than just planes? We spotted this stunning Elkhorn #coral (Acropora palmata) thriving on one of the runway dolos while snorkeling around! ✈️🫱🏾‍🫲🏼🪸 📸 @dan_mele_photography

We flirted with G5 storm conditions earlier with the precursor, but now the main event is here. We're inside the core of the #solarstorm and entering G5-level territory again. This time to stay. It would not surprise me to see G5 conditions for the next 6+ hours. Expect sporadic #GPS signal reception issues, HF/VHF #radio disruptions, deep into to mid-latitudes, plus visible #aurora down to low-latitudes over the next 6-12 hours!

Hurricane Helene hitting the gas this afternoon Enormous reservoir of deep, warm water from Loop Current will continue to fuel storm into landfall. Don't even need this for a major hurricane -- can happen regardless. This is extra juice.

This little eddy is actually a speed bump -- albeit relative to its surroundings. However, in the next 6-hours, Helene will go over the Loop Current w/rocket climate-fuel.

Dear friends who write NSF GRFP rec letters, this year rec letters are due BEFORE the applications, so about 10 days earlier than normal on Oct. 11. Please don't let NSF's deadline change on rec letters screw over the applicants in your lives.

Today in Intro to Animal Microbiomes, we are doing an in-class assignment in which we hand-align DNA sequences and make small ordinations and phylogenetic trees.

History/oceanography tweeps: did the Challenger Expedition have livestock on board? I saw a drawing that appears to show a cow laying on deck while men strain sediment, but I don’t remember reading about them taking livestock along. Perhaps picked up in port somewhere?

The U.S. has been pumping sand onto eroding beaches for nearly a century. As climate change worsens, there’s no end in sight trib.al/uMceCBL
