    Side Trip to Hiron Point, Sundarbans

    After helping Chris an Dan with soil salinity and reflectance measurement, Humayun, Liz and I moved onto the smaller M.B. Mewl to sail through the Sundarban Mangrove Forest to service our GPS station at Hiron Point.

    Equipment Repairs in SW Bangladesh

    Humayun, Liz and I headed to Khulna in SW Bangladesh a day after Chris and Dan. Along the way, we stopped at our sediment compaction meter for surveying and removing the GPS, and getting feasted by the family that hosts the system.

    Back to Bangladesh to Date Earthquakes and More

    I’m back in Bangladesh with a small team after a year and a half away. One different is a police escort as a result of the attacks last year. We start by successfully sampling river sediments to correct the date of an earthquake that caused a river to shift over 3,500 years ago. We also…

    Columbia, Princeton Scientists Share 2017 Vetlesen Prize

    S. George Philander of Princeton University and Mark A. Cane of Columbia University’s Lamont-Doherty Earth Observatory, who untangled the complex forces that drive El Niño, the world’s most powerful weather cycle, have won the 2017 Vetlesen Prize for achievement in earth sciences.

    Antarctic Scientists Honor Obama by Collecting Climate Data

    Researchers studying the West Antarctic Peninsula marine ecosystem will recognize President Obama’s efforts to combat global warming by collecting climate data at an oceanographic station they named for the 44th president.

    Green Sahara’s Ancient Rainfall Regime Revealed

    Rainfall patterns in the Sahara during the six-thousand-year “Green Sahara” period have been revealed by analyzing marine sediments, according to new research.

    Lamont to Develop New Earthquake and Tsunami Warning System

    A new pilot program led by the Lamont-Doherty Earth Observatory aims to provide earlier and more accurate warnings of damaging ground-shaking from earthquakes and the imminent arrival of tsunamis.

  • Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice

    Radar Reveals Meltwater’s Year-Round Life Under Greenland Ice

    An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.

    Exploring Our Changing Earth, in Real Time

    Lamont-Doherty Earth Observatory scientists are loading drones with high-tech instruments and using satellites and undersea cables that are interacting with sensors in some of the most remote locations on Earth to gather data in real time and uncover the secrets of our planet.
