‘Popping Rocks’ and Robots
It turns out that studying lava flows at the bottom of the ocean uses many of the same methods as studying lava flows on other planets, writes Lamont’s Elise Rumpf.

Mozambique Core Brings Up 7 Million Years of Climate History
With calm seas, the JOIDES Resolution’s latest sediment core comes up with what appears to be a fantastic, cyclic climate signal that is continuous back 7 million years, writes Sidney Hemming.

We’re Headed for Mozambique!
After weeks of anticipation, permission arrived just in time to core off Mozambique. Sidney Hemming and her team of scientists aboard the JOIDES Resolution are excited about what they might learn from the ocean sediment.

Trials & Tribulations of Coring the Agulhas Plateau
Trying to drill sediment cores while the ship rides large ocean swells off the coast of Africa isn’t easy, but it’s paying off for science, writes Sidney Hemming.

Exploring Ocean Turbulence: 2016 Sloan Fellow Ryan Abernathey
When you examine the behavior of the global oceans closely—really closely, at scales smaller than 100 kilometers—eddies and jets and fronts start to appear. For Ryan Abernathey, this is where ocean physics gets interesting.

A New Tool for Coastal Planners Preparing for Sea Level Rise
Globally, the tool estimates at least 11 inches of sea level rise this century with ambitious efforts to lower greenhouse gas emissions and as much as 52 inches if greenhouse gas emissions continue to grow unchecked.

6 Million Years of Sediment, Studded with Tiny Fossils
Sidney Hemming and her team have started examining their first sediment core from off southern Africa. It appears to contain about 6 million years of history.

Gearing Up for Our First Cores
As they get to know their ship, the scientists aboard the JOIDES Resolution prepare to drill their first sediment cores along the Natal Valley off the coast of southern Africa.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
