    Arctic Magic: One Research Vessel Multiplies to Hundreds

    The Arctic is magical, that we know, but when one ship multiplies to hundreds of small boats we really see the effect that Arctic magic can bring.

    Translating Nature’s Historians: The Tree Ring Lab Turns 40

    In its first 40 years, the Lamont Tree Ring Lab tracked changing climates around the world, building an international reputation as a global leader in research, training and technology.

    A Week of Firsts for This Arctic Nation

    We are closing in on a week of intense focus and excitement for GEOTRACES and for the United States around the Arctic. President Obama became the first sitting president to visit Alaska, the US Coast Guard Cutter Healy with US GEOTRACES scientists completed the first unaccompanied US surface vessel transit to the North Pole, and…

    It’s as Clear as Mud

    For the sampling GEOTRACES is doing in the Arctic there is a specific goal of collecting just the top few dozen centimeters of sediment and the water just above it. Although the plan was good, things don’t always go perfectly.

    Q&A: Park Williams on Drought, Climate and ‘Cracking the Code’

    “Future extremes are going to occur more and more frequently. In planning, we don’t need to plan for the 2 degree warming that we are aiming for as a globe, we need to plan for the 10 degree increase in a day, or the year when there’s no water. We need to plan for worst-case…

    Internships: Work with NASA Scientists on Climate Change

    An internship program at the NASA Goddard Institute for Space Studies in New York is offering graduate students a chance to work with NASA scientists on climate change research.

    Moving into the Realm of the Polar Bear

    When we venture into the Arctic for research for most of us there is the lingering hope that a polar bear will appear on our watch; at least as long as we are safely outside of its reach.

    Tree Rings on Hawai’i Could Hold New Knowledge About El Niño

    Annual tree rings are a rare find in the tropical islands of the eastern Pacific. The new discovery of trees with annual rings on a Hawaiian volcano could provide new climate data from a part of the world where much of the variability of the El Niño-Southern Oscillation originates.
