    Earth Institute Scientists Drill Into the Oil Spill

    Earth Institute scientists have begun research into the Gulf oil spill’s physical and ecological impacts, both on land at sea. While much attention has focused on surface oil washing up along the shores of Gulf coast states, one cruise starting in mid-August will study the location and magnitude of subsurface oil plumes, and their effects…

    A final note (for now) on the expedition to recover ice cores from the top of Puncak Jaya in Papua, Indonesia: the cores arrived safely on Thursday, July 22, at Ohio State University’s Byrd Polar Research Center, and are now in a special freezer. In coming months, the team hopes to extract and interpret climatic…

    I have reached Jakarta, and so have the ice cores, which are being kept frozen while awaiting air shipment to the United States. The rest of the team has already returned to their homes. Next for me: back to sea level, on two research cruises that will add oceanographic information to the data we gathered on Puncak Jaya.…

    Nano and I took the train to Rome to meet a colleague for lunch, and after we explored the old city. I have been through Rome a number of times, making my way to and from Calabria, but this was my first time really seeing the city. Nano was a fantastic tour guide. He was…

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
