    Scientists Are Mapping New York City Wildlife. And We Don’t Mean Rats, Squirrels or Pigeons.

    Raccoons, coyotes, possums and other wild mammals are becoming more common in the country’s most densely populated city. New research aims to map their populations and habits in hopes of decreasing conflicts with humans.

    Sylhet City, Geology, and Packing Up

    We finished our electromagnetic survey and mini-field school in northern Sylhet, Bangladesh, with lectures and field trips to see the geology by car and boat.

    Community-Led Science Uncovers High Air Pollution From Fracking in Ohio County

    In a collaboration that included Columbia researchers, Belmont County residents set up a low-cost sensor network that is helping them fight for clean air.

    Start of the Mini-Field School

    We were joined in our electromagnetic investigation of the subsurface and earthquake hazard by a group of US and Bangladeshi students and professors for a mini-Field School.

  • Tea Gardens to the Rescue

    Tea Gardens to the Rescue

    We switched to deploying our equipment for imaging faults and the structure beneath the surface to tea gardens to get away from power lines and buried the cables to protect them from gnawing foxes.

  • Dealing With Rain and Rats

    Dealing With Rain and Rats

    As we continued our geophysical measurements, we had to deal with heavy rains, flooding fields, and rats and foxes biting our cables. Many cables were broken soon after sunset, ruining the measurements.

  • Struggling With Towed Equipment, Repairing GPS, and Home

    Struggling With Towed Equipment, Repairing GPS, and Home

    We switched to a towed electromagnetic system to image the fresh and saline groundwater in Bangladesh, and ran into a variety of problems, including high winds, strong currents and running aground.

  • Continuing the Survey: Watermelon and Winds

    Continuing the Survey: Watermelon and Winds

    Continuing our electromagnetic survey of fresh and saline groundwater, we saw the landscape change from lush watermelon fields to fallow rice fields as the salinity increased towards the sea.

  • Barisal and the Eastern Channel

    Barisal and the Eastern Channel

    We are continuing our measurements of fresh and saline groundwater in Bangladesh using electromagnetic instruments. We finished our first set of measurements and have now shifted farther east near Barisal where groundwater is fresher.
