Students collect scientific information to create snapshots of the river at dozens of locations, then share their data using Web-based technology so they can better understand how their piece of the river fits into the larger Hudson estuary ecosystem. Sponsored by DEC's Hudson River Estuary Program and produced with assistance from the Lamont-Doherty Earth Observatory of Columbia University, Day in the Life coincides with National Estuaries Day and World Water Monitoring Day.

At each location, teams of students and environmental educators use seine nets, water testing kits, and measuring tools to investigate aquatic life, water chemistry, tides and weather. Many groups also collect core samples of river bottom mud for analysis. Download a list of schools and sites that participated on October 20, 2015 (PDF, 260 KB)

Participants' findings contribute to ongoing research projects, and data from the event are incorporated into lesson plans developed by the Hudson River Estuary Program and available to all teachers in the Hudson Valley.

Where possible, Estuary Program staff facilitate partnerships between participating classes and local environmental education organizations for Day in the Life. Training workshops, online lesson plans, specialized equipment, thirteen years of results, and other resources are provided.

A Day in the Life of the Hudson River Estuary 2015

The thirteenth annual Day in the Life of the Hudson River in 2015 was a huge success! More than 5,000 participants sampled the estuary at over 80 locations! Thanks to the students who shared their findings, Estuary Program staff were able to create the following place-based, data-driven worksheets for classroom use.
