Presenters: Margie Turrin, Director of Educational Field Programs, and Laurel Zaima, Education Program Assistant, Lamont-Doherty Earth Observatory Description: The Hudson River estuary spans 153 miles from the Troy dam down to the tip of the New York Battery and it is a wonderful educational feature located in our very own “backyard.” We are going to be using real data collected from the “Day in the Life” program to explore the dynamic nature of the salt front and the diverse fish communities that call the Hudson River estuary home.
