  • The Sphinx of Greenland

    The Sphinx of Greenland

    I had been warned of Geikie. “If they fly to Geikie get on that flight” I had been told, but nothing more.

  • Connecting the past, the present and the future to understand climate

    Connecting the past, the present and the future to understand climate

    Over 100,000 years of Arctic climate data has been linked in the last two days of Ice Bridge missions. When you see the names DYE2, EGIG, GRIP, Ice Bridge and MABEL you view the elite list of Arctic science projects that deliver(ed) groundbreaking climate information through the last 50 years, and if all goes as…

  • Leveraging the Moment

    Leveraging the Moment

    Time takes on a new meaning in the field. Every moment is compressed in order to gain maximum yield. Applying human accounting, field time is limited by available resources, personnel, and funds, while using nature’s accounting the limits shift to windows of weather, and seasonality for ice phenomena. In the field both human and nature…

  • On the Heels of History

    On the Heels of History

    Perhaps the most natural connection between the explorations of the past and today’s carefully planned scientific missions is through the hand of fate and the crush of nature.

  • The Climate Irony Catches Greenland

    The Climate Irony Catches Greenland

    In mid-season, the Ice Bridge mission is assessing land ice along the Greenland perimeter and interior, to measure the impact of a changing climate in one of the most remote places on Earth.

  • Switchyard Project: A Very Successful Year

    Switchyard Project: A Very Successful Year

    The 2011 field season has been a very very successful year, in fact the most successful one we have ever had. The weather has been great, the equipment proved to be mostly reliable, the people have been great and the samples are plenty.

  • A Focus on the Thinning Northwest Greenland Glaciers

    A Focus on the Thinning Northwest Greenland Glaciers

    Blog by Hakim Abdi, LDEO Satellite measures showing thinning ice on the Northwest Greenland glaciers prompted Operation IceBridge to include annual flights over this region. The area runs along the Baffin Bay coast, which is often covered in fog and low lying clouds forcing delays and reschedules. With the end of our season in sight…

    Measuring Gravity From a Moving Aircraft Requires a ‘Gravi-God’!

    From: Joël Dubé, Engineer/Geophysicist at Sander Geophysics, OIB P-3 Gravity Team One of the instruments used in Operation IceBridge (OIB) is an airborne gravimeter operated through a collaboration between Lamont Doherty Earth Observatory of Columbia University and Sander Geophysics of Ottawa, Canada.  People from other instrument teams have been heard to call it a gravity…

  • Switchyard Project: Melting Ice, a Fresher Arctic

    Switchyard Project: Melting Ice, a Fresher Arctic

    The freshwater content of the Arctic Ocean is increasing as the Earth’s climate warms. Chemical analysis indicates that the source is both melting ice and the Pacific Ocean.
