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.

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.

Bridgit Boulahanis, a marine geophysics graduate student at Lamont-Doherty Earth Observatory, prepares to head out on her first research cruise exploring the seafloor with underwater vehicles.

Twelve students from New York and New Jersey are spending July in laboratories at Lamont-Doherty Earth Observatory, working with the scientists. The internship program enables students to spend four weeks exploring what it means to be an earth scientist.

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.

A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth’s mantle flows beneath the ocean’s tectonic plates.

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.

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.

On June 24, a scientist involved in the CarbFix carbon capture and storage project in Iceland will give a live-streamed presentation about the technology and the project's success at turning CO2 to stone.

A new initiative aims to help homeowners in New Jersey cope with arsenic contamination in private wells—a problem that has only come to light in recent years, and about which many homeowners are still unaware.

The tropics are already hot, and they’re getting hotter as global temperatures rise. A new study offers a glimpse into how seriously a couple more degrees could disrupt the region’s ecological map.

East Africa's rift valley is considered by many to be the cradle of humanity. In the Turkana region of northwest Kenya, researchers Christopher Lepre and Tanzhuo Liu of Columbia University's Lamont-Doherty Earth Observatory are cooperating with colleagues to study questions of human evolution, from the creation of the earliest stone tools to climate swings that have affected developing civilizations.
