New study finds that cleaner air has accelerated increase in heatwaves. "The findings are compelling and add to a growing body of literature on how aerosols can have out-sized impacts on climate extremes," says @LamontEarth's @d_westy. Via @newscientist. newscientist.com/article/248904…

New study by @LamontEarth postdoc Collin Brandl & colleagues reveals first detailed images of newly developing subduction zone off coast of British Columbia’s Haida Gwaii archipelago, with data collected during 2021 cruise on Lamont's R/V Marcus Langseth: lamont.columbia.edu/news/seismic-s…

🚢 Every successful CTD deployment on the R/V Marcus G. Langseth starts here, in the Winch Booth, perched above the working deck with one of the best views on the ship. Science officer Cody Bahlau reported from expedition MGL 2506: instagram.com/p/DMc6n6pyedP

Found a stowaway in my bunk! My daughter’s @squishmallows toy is along for the ride to Galapagos on Research Vessel Langseth!! @TheJR @LamontEarth #NSFfunded #SOR2025 #Langseth

Opening a ship’s water tight door feels like a sailing right of passage! Here’s my first go! @TheJr @LamontEarth #Langseth #NSFfunded #SOR2025

Learning about the research operations we’ll have the chance to assist with & practicing some new skills. Thanks for schoolin’ the teachers @OlinCollege’s Victoria Preston & @LamontEarth’s Todd Jensvold @TheJr #Langseth #NSFfunded #SOR2025

Gadgets galore on the R/V Langseth’s bridge. Captain Breck Crum gave us a crash course in the navigation, steering, autopilot (iron Mike), AIS, and communication systems of R/V Langseth. @TheJr @LamontEarth #Langseth #NSFfunded #SOR2025

Excited to my core to revisit microfossils during @TheJR school of rock! It’s been a while since I looked at #forams but the great news is, using a scope and picking is just like riding a bike! @LamontEarth #Langseth #NSFfunded #SOR2025

Our @TheJR School of Rock journey begins! Teacher participants & facilitators have the chance to meet and enjoy our last bit of time on land in beautiful San Diego! The boats are giving us a taste of what’s to come… @LamontEarth @Columbia #NSFfunded #Langseth

Ahoy R/V Langseth! Boarded and braced for adventure! @LamontEarth @TheJR @GeneralsPride @APSVirginia #NSFfunded #Langseth #SchoolofRock

Safety first! This definitely beats the usual Bloodborne Pathogens teacher safety training! @TheJr School of Rock aboard R/V #Langseth @Columbia @LamontEarth @GeneralsPride @APSVirginia #NSFfunded #teacherlife

Doing a little science before we push off! Using a Secchi (rhymes with Becky) disk to measure water turbidity (cloudiness) around the R/V #Langseth @TheJr @LamontEarth @GeneralsPride @APSVirginia #NSFfunded #SOR2025

🚢 R/V Marcus G. Langseth science officer Cody Bahlau reports from expedition MGL 2506 where researchers are using precise water sampling to investigate how microbial communities transfer energy and influence carbon cycling across the California Current: instagram.com/p/DMVrcF6tHAy

“To infinity and beyond!” Actually, to @TheJR School of Rock aboard @Columbia ship R/V Marcus G. Langseth and beyond!! I’ll join teachers from across the country for a professional learning expedition to Galapagos! @AlaskaAir @LamontEarth @APSVirginia #NSFfunded #Langseth

On field trip to Gowanus Canal organized by @ColumbiaMSPH's Michael Musso, @LamontEarth's Steve Chillrud, @frogg_brooklyn, @ColumbiaMPA_ESP students saw how science, policy, community action intersect to address longstanding urban environmental problems: news.climate.columbia.edu/2025/07/14/tox…

New study led by Yanan Fang of Nanjing Institute of Geology & Palaeontology and Paul Olsen of @LamontEarth shows that the Mars–Earth orbital cycle once had a 1.6-million-year cycle that coincided with major climate swings. ➡️ lamont.columbia.edu/news/chaotic-m…

Researchers suspect that two meteorites found in Sahara Desert may be from Mercury, which would be first ID'd fragments of solar system's innermost planet. Sean Solomon, @LamontEarth geophysicist/NASA MESSENGER mission to Mercury PI, weighs in. Via @CNN. cnn.com/2025/07/14/sci…

Why are flash floods getting worse, and how can you best stay safe? Experts @jeffschlegel of @columbia_ncdp and Jason Smerdon of @columbiaclimate and @LamontEarth explain. Via @TIME. time.com/7302498/flash-…

Leanne Phelps and Kristina Douglass of @columbiaclimate discuss their new study on how diverse African communities adapted to climate variability over the past 10,000 years, with novel insights into how livelihoods formed and evolved. Via @ConversationUS. theconversation.com/africans-survi…

The atmosphere is warm, and warmer air can take more moisture, which hits a cold front and creates street flooding. Given the lack of interaction between the city and the MTA, you then get subway flooding, says @LamontEarth's Klaus Jacob. Via @THECITYNY. thecity.nyc/2025/07/15/sub…
