    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

    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.

  • Going Deep for Science

    Going Deep for Science

    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.

  • A Summer of Hands-on, Minds-On Science

    A Summer of Hands-on, Minds-On Science

    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.

  • New Group Takes On Massive Computing Needs of Big Data

    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.

    New Study Upends a Theory of How Earth’s Mantle Flows

    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.

  • Massive Landslide Detected in Glacier Bay’s Fragile Mountains

    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.
