“During the period of study [1930 - 2015], we estimate that Tropical Cyclones contributed to more deaths in the continental US (3.6–5.2M) than all motor vehicle accidents (2.0M), infectious diseases (1.9M) or US battle deaths in wars (1.3M).” 1/2 www.nature.com/articles/s41...

“It all just floods and dries up, and it’s really hot. We don’t have sustained recharge occurring.” What is a groundwater drought and how does the Barton Springs Aquifer recharge? Answer, it's complicated! thedailytexan.com/2025/09/23/b...

🚨New publication Exp398 data show deposits of volcanic particles have higher seismic velocities than other marine sediments, despite having lower densities. The study can help guide the interpretation of seismic images of seafloor deposits. #NSFfunded agupubs.onlinelibrary.wiley.com/doi/10.1029/...

The leaves are trying to tell us something.

The days are getting shorter and if you're looking for some fall entertainment, my favorite summer reads were: Airborne - @carlzimmer.com Into the Planet - @jillheinerth.bsky.social How the World ran out of Everything - @petersgoodman.bsky.social City Limits - @megankimble.bsky.social

"Cycling isn’t just good for the planet, your wallet and your fitness. Choosing this form of transportation for your errands instead of driving or taking the train may also help you prevent cognitive decline, a recent study found." www.cnn.com/2025/09/20/h...

„The 160-metre-wide asteroid smashed into the sea causing a 100-metre-high tsunami, say scientists. It was probably a very bad day for any early mammals in the area“ www.theguardian.com/science/2025...

Finally, some good news. 🌊 www.nytimes.com/2025/09/19/c...

Every night, billions of tiny fish rise from the deep in Earth’s largest migration. A new @jexpbiol.bsky.social study confirms what scientists long suspected: mesopelagic fish help lock carbon in the deep sea for centuries. Small fish, big climate impact. 🔎 More: https://bit.ly/4goVkiW

This year, the ozone hole presented an early development, reaching a larger-than-average area mid-September. On #WorldOzoneDay, #CopernicusAtmosphere continues to provide tools for everyone to monitor the health of our planet.

Whoa, kind of mind-blowing. The rocks above the end-Cretaceous mass extinction look different than the ones below it because of the ways that dinosaurs modified the environment. www.nature.com/articles/s43...

Because a complete map of the ocean underpins global progress. It gives us the knowledge we need to plan safe shipping routes, protect marine ecosystems, respond to natural disasters and manage resources sustainably.

The Gulf & Western Caribbean are record hot now. On the right top: record hot areas in deep red. Bottom: Gulf Temps over the last 40 years. The blue line on top is 2025, which is now in record hot, just ahead of 2023 and 2024, the two hottest years prior. The Gulf is warming due to climate change 1/

Few years ago, French science magazine Science & Vie used some of my photos to illustrate the outlandish proposals of building massive pillars on the seafloor to hold back glaciers, or a km-high underwater wall around the continent to block warm deep-water. 🤪 www.science-et-vie.com/article-maga...

🧪🧵 To be clear about this, within a few years temperatures will permanently exceed 1.5°C above pre-industrial, beyond which the risk of triggering several climate tipping points greatly increases. To minimise these risks we need action now. 1/n

Craving a cold soda 🥤 or a bowl of Spaghetti Ice Cream 🍝 (yes, google it, it’s amazing!) when it’s hot? A new study found that that added sugar consumption is positively related to temperature, notably within 12–30 °C at a rate of 0.70 g  per °C. www.nature.com/articles/s41...

"Why try? In just 5 years, [...] global demand for fresh water will exceed supplies by 40%. Rising sea levels from the warming climate are souring coastal freshwater sources while data centers that power AI and cloud computing are consuming water at an insatiable rate." apnews.com/article/fres...

Looks like the Gulf‘s heat battery is being charged, without any hurricanes feeding on its energy…so far. 😳

Earlier this year, IODP³-NSF Expedition 501 drilled on the New England Shelf to better understand groundwater below the seafloor. youtu.be/a5JU-WSxO_E?...

A champagne bar next to your undersea high-speed train, vast bicycle garages, H₂-powered trains, and suspended trams are only a few examples of Europe falling behind. Robotraffic is still traffic, as the cartoon highlights well, and I'd rather see accessible and integrated alternatives to that!

From the tropics to the poles, the deep sea to the mountains, tiny to massive, it’s #NationalWildlifeDay! It’s truly a great privilege to have seen so much of our planet’s wild side and hope we will preserve, protect, and restore it.

For the first time in four decades, Panama's annual ocean upwelling in the Gulf of Panama did not occur in 2025, linked to weakened trade winds and highlighting climate impacts on marine systems.

What people think I get injured by (sharks), vs. what I really got injured by just a week later (hit by a driver backing out a driveway & running over my bike). 2024 saw 47 unprovoked shark attacks with 4 fatalities worldwide, while 1166 cyclists died in US traffic crashes! @thewaroncars.bsky.social

In the summer of 1985, WHOI & @ifremer.bsky.social set out into the N.Atlantic to try to find the wreckage of RMS #Titanic. 🤫 In the early morning hours of Sept 1, the fatigued WHOI team recognized one of Titanic’s boilers, and the rest is history. 📲Dive into discovery: go.whoi.edu/titanic-1985

Autonomous Surface Vehicles are a more & more common sight at sea. This looks like a defense version of the Lightfish AUV. Its yellow science siblings have been deployed to monitor algal blooms & wildlife, map undersea bathymetry... Maybe these will help @seabed2030.bsky.social to map our oceans?

Under high-emission scenarios, the Atlantic Meridional Overturning Circulation, a key system of ocean currents that also includes the Gulf Stream, could shut down after the year 2100. www.pik-potsdam.de/en/news/late...

After her epic dive, @geoshanz.bsky.social made me aware of Kelp Rafted Debris. Though working with Ice Rafted Debris, I had no idea that KRD even exists. Now I just had a chance encounter with a kelp paddy ∼15mi off CA and guess what, its root system was clinging to a bunch of pebbles! So cool! 1/5

The latest #TalesFromTheDeep episode on the StoryCorps Archive is from Carl Brenner, director of the U.S. Science Support Program for scientific ocean drilling.

I’ve always been fascinated by the great pelagic wanderers of the oceans. Swordfish, tuna, whales, even the odd mola, but most of all the amazing mako shark. Together with @ucsandiego.bsky.social scientists, I finally had the chance to observe one in the wild.

Hey everybody! @drjuliawester.bsky.social and I have a new paper! We surveyed over 800 scientists, science communicators, and science educators who use social media. Conclusion: Scientists no longer find Twitter useful or pleasant, and many have switched to Bluesky! 🧪🌎🦑 doi.org/10.1093/icb/...

100 years ago today, the Spitsbergen Treaty came into force. To this day, it forms the basis for international research in the Arctic and enables scientists to work in this dynamic environment. Last year, IODP Exp403 had the privilege to work off Spitsbergen's coast. iodp.tamu.edu/scienceops/e...
