    What’s a Few Days’ Delay When Preparing to Visit a 33 Million-Year-Old Ice Sheet?

    With the Rosetta-Ice team delayed in New Zealand, let’s take a minute to discuss why Antarctica’s weather is so forbidding.

  • Final Stop: Antarctica’s Ross Ice Shelf

    Final Stop: Antarctica’s Ross Ice Shelf

    We have embarked! Our third Antarctic field season is underway, putting us only 18 flights away from completing our mission to map the Ross Ice Shelf, the largest ice shelf in Antarctica.

    With its mission complete, the Rosetta-Ice Project will give scientists an unprecedented look at the Ross Ice Shelf and how it’s changing with the climate.

    Lamont Scientists Are Focus of NY Times Multimedia Series

    This past winter, reporters from the New York Times went along for the ride with scientists from the Lamont-Doherty Earth Observatory as they flew their mission of discovery over Antarctica.

    Kirsty Tinto: Mapping on and under Antarctica’s Ice

    Kirsty Tinto flies aboard a specially equipped airplane in very cold places to study ice sheets and ice shelves. She’s an associate research scientist in the polar geophysics group at Lamont-Doherty Earth Observatory.

  • The ‘Bird’ Has Flown!

    The ‘Bird’ Has Flown!

    The ‘bird’ has flown! Voices are raised in celebratory cheers from the southernmost continent to across the U.S. Our first ALAMO float is deployed! Now we can begin to answer some of the big questions on this mysterious ice/ocean interface.

  • A Texas-Sized Block of Ice…

    A Texas-Sized Block of Ice…

    The Ross Ice Shelf is the largest of the Antarctic ice shelves, measuring just under the size of the state of Texas. It is several hundred meters thick, although most of this is below the water surface. Along the ~ 600 kilometer front edge of the shelf, the ice towers up to 50 meters in…

  • This Bird Flies South for the Winter

    This Bird Flies South for the Winter

    Migrating south in the winter is a behavior that Antarctic scientists share with many species of birds, although the scientists fly just a bit further south. For the IcePod team it was time to join the migration so they could test their equipment in the most challenging environment the Earth has to offer.

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
