New paper alert! Led by Alexa Cacacie and @nathanbfurey.bsky.social, we used otolith chemistry to assess migratory diversity in Rainbow Smelt. Patterns varied among individuals, but not btwn sexes. More at the link! link.springer.com/article/10.1...

Did you know Benjamin Franklin discovered the Gulf Stream? In 1769, Franklin’s Gulf Stream chart was printed—the first map of the oceanic current ever published. Two more editions followed, but the original map disappeared for nearly 200 years. Learn how it was found: go.whoi.edu/Franklin

A shocking new poll result: Many Americans somehow don't have a favorite dinosaur. And only 6% give the correct answer (triceratops). Check out YouGov's new polling on Americans and dinosaurs: yougovamerica.substack.com/p/whats-your...
A split bar chart of YouGov polling data with the headline: "Americans are most likely to say T. Rex is their favorite dinosaur, but many don't have a favorite."

The chart has the sub-headline: "Which of the following is your favorite dinosaur? (%)."

The chart has the note: "Note: "Other" includes responses of archaeopteryx, spinosaurus, plesiosaur, ankylosaurus, allosaurus, parasaurolophus, dilophosaurus, diplodocus, iguanadon, and pachycephalosaurus, as well as responses of "other." We know pterodactyls and plesiosaurs aren't dinosaurs. Opinion about dinosaurs comes from the question, "How much do you like or dislike dinosaurs?""

Dewey Mears took this moody, atmospheric photo of Austin's Congress Avenue in 1947. It's almost film-noirish, isn't it? I wonder what it was like to walk down the sidewalk when Austin was a normal, quiet town. 😉 From the Austin History Center, a great place to visit if you're in downtown Austin.

Fig. 2.
Warming stripes for the surface and ocean depths (1960–2024) and for different layers of the atmosphere (1979–2024). Anomalies relative to the 1981–2010 period are shown, with different color scales for the stratosphere, troposphere, upper ocean, and deeper ocean, with these layers separated by the gray horizontal lines. The global surface temperature data are from HadCRUT5. Global average temperatures for tropospheric layers are from RSS, with stratospheric layer global temperatures updated from Steiner et al. (2020). Ocean data are from Met Office Statistical Ocean Reanalysis (MOSORA) (Smith and Murphy 2007), globally averaged for different depth levels.

Marjorie Courtenay-Latimer was born #OTD (South Africa, 24 Feb 1907-17 May 2004). She's best known for her key role in the 1938 rediscovery of the #coelacanth, a #fish with a fossil record going back 410mya but assumed #extinct since K-Pg 66mya. See ALTs for more info!
This is her original sketch and desciption of the specimen she recovered from a South African fishing boat's catch and did her best to preserve until the ichthyologist she was writing to, J. L. B. Smith (South African, 1897 - 1968) could arrive to identify it. He was indeed able to confirm it was the long-lost Coelacanth, and give the genus the scientific name Latimeria in her honor.
(Image: SAIAB)Here too is a commemorative 4-stamp set issued by South Africa in 1989, designed by Sheila Nowers:
"Identification of the Coelacanth 50 years ago"*
6c Latimeria chalumnae underwater

(*It was found in December 1938, but Smith didn't arrive to officially ID it until early 1939)The 1938 species is now known as the West Indian Ocean Coelacanth (Latimeria chalumnae), as there was a SECOND living species confirmed in 1999, named the Indonesian Coelacanth (L. menadoensis). Its find was commemorated by Indonesia with this 2000 souvenir stamp sheet.
