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.
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.
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.
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.
Who were our earliest ancestors? How and when did they evolve into modern humans? And how do we define “human,” anyway? Scientists are exploring Kenya’s Lake Turkana basin to help answer these questions.
To understand how quickly ice from glaciers can raise sea level or how moons far across the solar system evolved to hold vast, ice-covered oceans, we need to be able to measure the forces at work. A new instrument designed and built at Lamont does just that.
