    Into the Sundarban Mangrove Forest and Back

    For the last week of our trip, we traveled by boat to reach the sites where we are measuring subsidence in the Sundarban Mangrove Forest and nearby embanked islands.

    Researchers are mapping the seafloor and subseafloor between Haiti and Jamaica, to evaluate the potential for earthquakes.

    Marco Tedesco: Snow Man

    Although his parents wanted him to become an electrical engineer, Tedesco felt drawn to a life of research. Then he fell in love with snow. Now he is among the most well-respected and quoted polar experts in the world.

  • From Barisal to Khulna

    From Barisal to Khulna

    We continued to service our GNSS and RSET-MH equipment measuring land subsidence in coastal Bangladesh. Long distances, poor roads and slow ferries made for very long days, but we were able to complete the work at the sites.

  • Dhaka and Beyond

    Dhaka and Beyond

    After a week of meetings and a wedding in Dhaka, we headed back to the field to service equipment measuring land subsidence in Bangladesh.

  • Back to Bangladesh at Last

    Back to Bangladesh at Last

    I am finally back in Bangladesh after a pandemic hiatus. I need to repair precision GPSs that failed over the last few years. They are measuring tectonic movements for earthquake hazard and land subsidence, which exacerbates sea level rise.

    It was long accepted that the Vikings were the first people to settle the Faroe Islands, around 850 A.D. until traces of earlier occupation were announced in 2013. But not everyone was convinced. New probes of lake sediments clinch the case that others were there first.

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
