We present new high-resolution carbon isotope data from #Svalbard to investigate atmospheric CO2 during the Middle Devonian, particularly the Taghanic crisis (1/3).
Enjoying meeting with prospective Geosciences students at SLCC this morning! @ullafayette.bsky.social
Here are four photos of squiggly rocks on Earth. Can you guess which of these, if any, are evidence of past life on Earth? If we received similar photos, from let's say Mars, would we know if it is life or not?
Deadline Friday!

What many don't realize is that the annual average daily temperature for Lafayette, Louisiana (69F) falls right between that of Los Angeles (66F) and Bermuda (72F). Some might say we have the optimal Goldilocks temperature. I think the city should market that more.

Is it Gumbo Weather yet? @ullafayette.bsky.social Gumbo weather is defined as 1st day w daily maximum temperature <70F. Last year (2024) was latest in last 120 years. We had to wait til Nov 20! We are not hoping for a repeat. Want to play along? Post your guess below!
Great piece on what makes Lafayette, LA such a great place to live, work, and play! A vibrant small city filled with great culture and community; plus a top-notch R1 university! @ullafayette.bsky.social louisiana.edu/news/lafayet...
Lafayette is at a crossroads. The University sits at the hub of it all.
Prologue: Skip back to the turn of the 20th century when Lafayette as we know it was in its infancy. Back then, “downtown” meant dusty roads, a few streetlights and a railroad station.

We all know someone who pockets interesting rocks and places them in random spots around the house. Honestly, it’s a good habit – taking time to connect with nature, even in your own backyard.
