    Exploring Rugged Hills & Turbulent Waters 4,500 Meters Down

    Aboard a ship at the Mid-Atlantic Ridge, scientists are studying how the deepest and coldest waters mix with shallower waters, gaining heat in the process.

  • El Niño: Resources for Journalists

    El Niño: Resources for Journalists

    El Niño is earth’s most powerful climate cycle, influencing weather and affecting crops, water supplies and public health globally. What may be the strongest El Niño ever measured is now getting underway, and is already affecting parts of the world.

  • Tubewells to the Rescue

    Tubewells to the Rescue

    The resistivity testing was hampered by bad roads and flooded fields. The augering was proving similarly difficult in the thick muds of the abandoned channel. It was time to change to our alternative plan: drilling with tube wells. That worked better and we had turned a corner.

  • Climate Change Leaves Its Mark on the Sea Floor? Maybe Not

    Climate Change Leaves Its Mark on the Sea Floor? Maybe Not

    A new study in Science questions the provocative idea that climate change may shape the texture of the sea floor. A Snickers bar helps explain what’s really going on.

    Come Aboard: A Look at the R/V Marcus Langseth

    A new video produced by Columbia University tells the story of what the research vessel Marcus G. Langseth is all about.

  • Pani, Pani Everywhere

    Pani, Pani Everywhere

    Heading out to our field area, we discovered that the abandoned river valley we planned to study was completely flooded. There was pani—the Bangla word for water—everywhere.

  • Melting Ice, Suntanned Rocks and an Award-Winning Postdoc

    Melting Ice, Suntanned Rocks and an Award-Winning Postdoc

    Nicolás Young was just named a winner of a 2015 Blavatnik Award for his work measuring ice sheets in changing climates of the past. His new projects are taking glacier tracking to the next level.

  • Bangladesh and India, Too

    Bangladesh and India, Too

    Returning to Bangladesh for additional fieldwork, I stopped off in India for several meetings, but we found time for some sightseeing, too. We were able to see the Qutub Minar complex in Delhi as well as the Taj Mahal and Agra Fort in Agra. Plus all the meetings in Delhi, Kolkata and Dhaka were very…

  • Anatomy of an ‘Ice Station’

    Anatomy of an ‘Ice Station’

    Completing an “Ice Station” means collecting samples over a wide range of Arctic water and ice conditions. Each station means a major orchestration of people and resources.
