Mapping the Seafloor
One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and…

In the Ice
Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze.

Closing in on Antarctica
We are less than a day away from our first study area on the continental shelf in front of the Dibble Glacier. As we approach Antarctica we are starting our science program with a 4500 meter deep CTD and multibeam acquisition.

On Our Way: Avoiding the Storm
We are now aboard the R/V Palmer and on our way to East Antarctica. Due to two storms in our direct way we are heading west first to go around the storms and we’ll then head south on their backside.

John Oliver, a Father of Plate Tectonics, Dies
Dr. John Ertle “Jack” Oliver, a geophysicist with roots at Lamont-Doherty Earth Observatory whose research helped revolutionize our understanding of the basic forces shaping the planet, died of cancer at his home in Ithaca, N.Y., on Wednesday, Jan. 5, 2011. He was 87. Together with fellow Lamonters Bryan Isacks and Lynn Sykes, he wrote a…

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
