    How Climate Influences Wolf Recovery in California

    Some evidence suggests that the glaciers on Mt. Shasta might have something to do with the location of a newly-spotted wolf pack in northern California.

  • Glacial Earthquakes May Help Forecast Sea-Level Rise

    Glacial Earthquakes May Help Forecast Sea-Level Rise

    Glacial earthquakes are produced as massive ice chunks fall off the fronts of advancing glaciers into the ocean. A new study of the quakes’ mechanics may give scientists a way to measure ice loss remotely and refine predictions of sea-level rise.

  • Mt. Everest Not Safe from Climate Change

    Mt. Everest Not Safe from Climate Change

    Climate change has many asking if the days of being able to summit the world’s highest peak are numbered.

  • Smooth Sailing Back to Tasmania

    Smooth Sailing Back to Tasmania

    After a surprisingly smooth crossing of the Southern Ocean, with favorable winds we arrived back in Hobart, Tasmania. The weather maps show that we just got ahead of another big storm system.

  • 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.

  • 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…

    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…

    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.
