    Did New Zealand Dust Influence the Last Ice Age?

    Bess Koffman, a postdoctoral researcher at Lamont-Doherty Earth Observatory, recently traveled to New Zealand to collect dust ground-up by glaciers during the last ice age. In this photo essay, she explains how she collected the dust, what analysis looks like in the lab and what she hopes to learn.

    Keeping an Eye on Coastal Erosion

    Searching for a fast, simple and low-cost way to monitor Earth’s changing coastlines, a team of scientists, including Lamont-Doherty Observatory postdoctoral researcher and marine scientist Alessio Rovere, has found an innovative use for drones.

    Bricks, an Archeological Site and Home

    It was time to pack up and leave. Shofiq, who is from Sylhet, was dropped off near his home and the fellowship of the rocks was broken. We settled in for another long drive. We made an impromptu stop at one of the numerous brick factories scattered across Bangladesh. Here, the workers immediately started snapping…

  • Field School: Sylhet Tectonics

    Field School: Sylhet Tectonics

    Most field trips have a “death march” hiking a long way through forest, swamps, hills or deserts to get to a remote outcrop. We have a “death bus ride” instead.

    Field School: The Brahmaputra River

    The first day was very light for the jet-lagged students, just a short introduction to the field school and some background, and then introductions all around as we started to get to know each other. The final group of nine students finally arrived around 9 p.m. They were the most worn-out, bedraggled bunch of travelers…

  • Climate Scientist Is First Woman to Win Geology’s Storied Wollaston Medal

    A climate scientist who has suggested how mountain building can lower Earth’s thermostat and why ice ages sometimes wax and wane at different speeds has been awarded one of geology’s oldest and most coveted prizes: the British Wollaston Medal. The first woman to win a Wollaston in the prize’s 183-year history, Maureen Raymo, a researcher…

    Joanne Johnson and Lamont-Doherty, Collaborating on Glacial Research

    New research about West Antarctica’s Pine Island Glacier suggests the glacier’s recent and rapid thinning and melting may continue for decades or centuries to come. British Antarctic Survey’s Joanne Johnson’s research, done in collaboration with scientists at Lamont-Doherty, might not have been possible without Lamont’s effort to promote women scientists.

    Tangail and the Start of the Field School

    Feb. 21 is Language Day in Bangladesh. It is a holiday, now adopted by the UN as International Mother Language Day. It commemorates a day in 1952 when a crowd of Bengali students protesting Pakistan’s adoption of “Urdu and only Urdu as the official language of Pakistan” were fired upon by the police. It marks…

    GPS in Khulna and the Hidden Temple

    Rushing around SW Bangladesh by boat and car, we managed to install or repair four GPS sites in record time. We caught up our lost day and managed to get to the ruins of the Shakher Temple in the Sundarban mangrove forest.
