    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.

  • Water Is Streaming Across Antarctica

    Water Is Streaming Across Antarctica

    In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica’s ice during the brief summer. Many of the newly mapped drainages are not new, but the fact they exist at all is significant; they appear to proliferate with small upswings in temperature, so warming projected for this…

    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.

  • Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

    Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

    Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.

  • Antarctic Scientists Honor Obama by Collecting Climate Data

    Antarctic Scientists Honor Obama by Collecting Climate Data

    Researchers studying the West Antarctic Peninsula marine ecosystem will recognize President Obama’s efforts to combat global warming by collecting climate data at an oceanographic station they named for the 44th president.

  • Looking at Climate from All the Angles

    Looking at Climate from All the Angles

    The Earth Institute digs into the past, tracks the present and models the future of climate. We explore the broader issues surrounding climate change, seek ways to apply our knowledge to real solutions, and nurture collaboration among faculty and researchers in the natural sciences, social sciences and humanities, law, public health, engineering, architecture and urban…

  • 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.

    Antarctica Has a New Explorer in the Water Near a Key Ice Shelf

    The first of six ALAMO floats parachuted into the Ross Sea off Antarctica to begin profiling the water in a check for areas where warmer than normal water could put the Ross Ice Shelf at risk.

  • ‘Ghost Ice Shelves’ and the Third Antarctic Ice Sheet

    ‘Ghost Ice Shelves’ and the Third Antarctic Ice Sheet

    The Antarctica Peninsula has been referred to as Antarctica’s third ice sheet. Following behind the East and West Antarctic ice sheet in size, one might be inclined to minimize its importance in the effects of melting Antarctic ice, on changes in sea level and other impacts, but that would be an imprudent mistake. The peninsula…
