    Drought and Fire Activity: What’s Climate Change Got to Do with It?

    Lamont-Doherty Earth Observatory scientist Park Williams, recipient of a Center for Climate and Life Fellowship, is investigating the influence of climate change on droughts and wildfires.

    Construction in the Swamp

    Despite the miserable weather and ongoing rain, we constructed a wooden structure to hold the GPS receivers, solar panels and other electronic equipment between the three wells. We worked out how and where to mount the antennas and had parts made to accomplish it. Although I had to leave before it was completed, the team…

    Visit to a Different Delta: the Mississippi

    This summer I am in the Mississippi Delta in southern Louisiana helping to install an updated version of the compaction meters that we have in Bangladesh. The environment is quite different and we have arrived in the midst of an historic storm. Luckily for us the brunt of the storm is NW of us. So…

    Project Maps the Chemistry of the World’s Oceans

    Until recently, too little data existed about the distribution of trace elements and nutrients in the oceans to provide a global picture. In 2002, a group of scientists connected with Columbia University’s Lamont-Doherty Earth Observatory set out to fill those gaps.

    The Magic of Exploring Under the Sea

    It’s midnight on the ship, and the labs are filled with scientists busy examining samples. Two of them just got back from a trip to the seafloor, and the excitement is palpable.
