Life Aboard a Research Cruise: 24-Hour Workdays, Amazing Discoveries
When scientists say “research cruise,” they aren’t talking about sunny afternoons of shuffleboard and margaritas on deck. Life aboard a research vessel means tight spaces, few amenities, and long workdays.

Roving the Abyss: It Takes a Team
Bridgit’s first mission with the autonomous underwater vehicle (AUV) Sentry was a rousing success, including locating a patch of seafloor where methane is bubbling up.

When Doing Science at Sea, Prepare to Adapt
Bridgit’s research training cruise started with a fundamental lesson of ocean science: Science at sea requires constant adaptation. Morning fog meant rewriting dive plans and reconsidering priorities.

New Group Takes On Massive Computing Needs of Big Data
The sheer number of observations now streaming from land, sea, air and space has outpaced the ability of most computers to process it. The Data Science Institute’s newest working group —Frontiers in Computing Systems—will try to address some of the bottlenecks facing scientists working with these and other massive data sets.

Science And Sustainability Management: 20 Years of Columbia’s Earth Institute
This fall, Columbia University’s Earth Institute will mark its 20th anniversary. There were two central ideas that animated the creation of this university-wide institute. The first was to promote basic understanding of earth system science, and the second was to apply that knowledge to decisions made by governments and businesses around the world.

Massive Landslide Detected in Glacier Bay’s Fragile Mountains
A 4,000-foot-high mountainside collapsed in Glacier Bay National Park this week in a massive landslide that spread debris for miles across the glacier below. Scientists at Lamont-Doherty Earth Observatory are studying it to improve understanding of landslide risks.
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
