  • Taking a 4,000-Meter-Deep Profile of Antarctic Waters

    Taking a 4,000-Meter-Deep Profile of Antarctic Waters

    In addition to understanding potential pathways for “warmer” circumpolar deep water to reach the ice shelf, we are also measuring what the structure and properties of the water column are and determining if there is already warmer water on or near the continental shelf that could already interact with the glaciers of East Antarctica today.

  • A Climate Battle Cry for Earth Day

    A Climate Battle Cry for Earth Day

    A group of 17 renowned scientists from around the world are appealing for dramatic action to forestall the worst effects of climate change, issuing an “Earth Statement” that calls for a world powered with zero carbon emissions by mid-century.

  • Mapping the Seafloor

    Mapping the Seafloor

    One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and…

    Lamont-Doherty Strategic Plan

    Lamont-Doherty Earth Observatory has been a leader in the study of our planet since its founding 65 years ago. Today, Observatory scientists continue the institution’s long tradition of addressing important questions in the Earth and planetary sciences. 

  • In a Melting Iceland, Drilling Deep to Stem Climate Change

    In a Melting Iceland, Drilling Deep to Stem Climate Change

    Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.

    Photo Essay: Iceland at the Cutting Edge of Climate Change

    Iceland has a complicated relationship with climate change. As in much of the far north, global warming is already exerting many effects here–arguably both good and bad. Yet the country contributes relatively little to the warming, since most of its energy comes from geothermal and hydro plants, which produce little carbon dioxide. Now, it is…

  • Deep Sea Drilling Rules and the Transition from Fossil Fuels

    The now reorganized Minerals Management Service (MMS) was responsible for generating revenues by leasing federal lands for mining, or drilling, and then regulating the same mining operations it sold leases to. That is an inherent conflict of interest, but it gets worse: The MMS was a revolving door for fossil fuel companies.

  • In the Ice

    In the Ice

    Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze.

  • Closing in on Antarctica

    Closing in on Antarctica

    We are less than a day away from our first study area on the continental shelf in front of the Dibble Glacier. As we approach Antarctica we are starting our science program with a 4500 meter deep CTD and multibeam acquisition.
