Photo Essay: A Day in the Life of the Hudson River

Once a year, Piermont Pier becomes a field station, and local students, a team of environmental investigators. On Tuesday, scientists at Lamont-Doherty Earth Observatory led students through a series of field experiments designed to teach them more about the Hudson River. The students took water chemistry measurements and compared them to the Hudson’s tidal cycles. They cored sediments from the river bottom and pictured their stretch of the Hudson covered in glaciers. They mapped out how high the river may rise under several CO2-emissions scenarios.

Their investigations led to many questions by the end of the day.

“How can we slow down sea level rise?”
“Can we see extinction events in sediment cores?”
“Does plankton abundance vary with water temperature?”

Now in its 12th year, the event, called “A Day in the Life of the Hudson River,” was organized by the New York’s State Department of Environmental Conservation. All photos by Kim Martineau unless otherwise credited.

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
