    Creating Earthquake Heat Maps: Temperature Spikes Leave Clues in the Rock

    When a fault slips, the temperature can spike by hundreds of degrees, high enough to alter organic compounds in the rocks and leave a signature. Lamont scientists have developed methods to use those organic signatures to reconstruct past earthquakes and better understand what controls them.

  • Learning from Slow-Slip Earthquakes

    Learning from Slow-Slip Earthquakes

    Off the coast of New Zealand, there is an area where earthquakes can happen in slow-motion as two tectonic plates grind past one another. These slow-slip events create an ideal lab for studying fault behavior along the shallow portion of subduction zones.

    Forecasting for the In-Between

    We can do a good job forecasting the weather for a week or two, and we can settle on what the climate is likely to do season to season, a month to a year into the future. But what about in-between?

    IEDA: Revolutionizing Big Data

    The Interdisciplinary Earth Data Alliance is fueling groundbreaking multi-disciplinary discoveries worldwide. “This is a new era of data mining,” says IEDA Director Kerstin Lehnert, a geochemist at Lamont-Doherty Earth Observatory.

    Spy Satellites Reveal the Himalayas’ Changing Glaciers – in 3D

    Declassified spy satellite images are beginning to provide the first consistent look at how glaciers across the Himalayas are changing and what future water supplies might look like for millions of people.

    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.

  • ‘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…

    A Front Row Seat on the Ocean Floor

    Ocean scientists are, in their hearts, explorers. Our group aboard the R/V Atlantis may be more infected with the exploration bug than most. The first goal of our expedition makes that clear: We aim to map regions of the seafloor never before seen by human eyes.

  • The Domino Effect

    The Domino Effect

    Ice shelves can behave like dominos. When they are lined up and the first one collapses it can cause a rippling effect like dominos. We have seen this with the Larsen Ice Shelves. Named in series, the Larsen A, B and C shelves extended along the northeastern edge of the West Antarctic Peninsula, and covered…
