    Tree Rings Open Door on 1,100 Years of El Niño

    Scientists have used tree-ring data from the American Southwest to reconstruct a 1,100-year history of the El Niño cycle that shows that, when the earth warms, the climate acts up. The research may improve scientists’ ability to predict future climate and the effects of global warming.

    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.

    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

    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.

    Earth, Water and Sky –A Conversation with Pierre Gentine, a new Columbia Water Center Scientist

    Columbia Water Center welcomes Pierre Gentine, Assistant Professor of Applied Mathematics at Columbia University’s School of Engineering and Applied Science, as an affiliate researcher. Pierre’s groundbreaking research on the way soil moisture interacts with the atmosphere has implications for many of CWCs initiatives—from developing more efficient irrigation systems, to water resource management, to understanding floods.…

  • Switchyard Project: New Sampling Record

    Switchyard Project: New Sampling Record

    On May 10, we celebrated the sampling of our 10th station yesterday. These are more stations than we were ever able to get water samples from. Because of the ongoing good weather, we will certainly get one more station today, and hopefully many more during the next couple of days. So watch the posted video and celebrate with…

  • Switchyard Project: Sampling Success

    Switchyard Project: Sampling Success

    The past 1½ weeks have been very successful. Our team from Lamont-Doherty Earth Observatory was able to obtain water samples from eight stations, while the team from the University of Washington has already broken their all-time record of the past years of 18 stations. Today (May 7) is actually the first day we can’t fly…

    Switchyard Project: Rescue Operation

    Four people who tried to ski from the North Pole to Greenland got stuck on the ice and ran out of food. Since our team was out on the ice for sampling close to their location, we stopped sampling and picked them up.

    Switchyard Project: It’s all about the weather

    One can only imagine what kind of a pilot one has to be to fly in the arctic regions and land on sea-ice under weather conditions as we have experienced already – fog above the ice and clouds covering the area with very low visibility.
