The Story at the Bottom of the South China Sea
We have drilled 2,600 feet below the sea floor and in another 500 feet, will reach the crystalline igneous basalt of the ocean crust. Though finding the age of the basalt is our main aim, the thick sediments that overly the crust also have a story to tell.

Earth’s Climate History, Written in Dust
Dust blowing onto the oceans can help algae grow and pull CO2 out of the atmosphere. It influences the radiative balance of the planet by reflecting sunlight away. Scientists want to know what role this plays in the coming and going of the ice ages, and how it affects our climate.

Explore the Arctic Ocean With ‘IceTracker’
This week, we are launching a test of “IceTracker”—a tool that allows users to see the trajectories of Arctic sea ice forward or backward from any day between 1981 and 2012, as well as sea-ice speed, air temperature, water depth and the age of the sea ice.

The R/V Marcus G. Langseth: Ocean Explorer
The Marcus G. Langseth, a research vessel operated by Lamont-Doherty Earth Observatory, traverses the world’s oceans conducting marine seismic studies that contribute to new understanding of Earth systems. The ship typically spends half the year or more on research expeditions led by Lamont-Doherty scientists and colleagues from other research institutes.
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
