Students collect scientific information to create snapshots of the river at dozens of locations, then share their data via the web so they can better understand how their piece of the river fits into the larger Hudson estuary ecosystem. "A Day in the Life" is sponsored by DEC's Hudson River Estuary Program and produced with assistance from the Lamont-Doherty Earth Observatory of Columbia University.

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.

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.

For more information about Day in the Life as well as access to past data, instructions and recording sheets for gathering data, and visual aids, please visit the Day in the Life of the Hudson River Estuary webpage (link leaves DEC) on the Lamont Doherty Earth Observatory website, or contact Rebecca Houser at

A Day in the Life of the Hudson River Estuary 2016

The fourteenth annual Day in the Life of the Hudson River in 2016 was a huge success! More than 4,500 participants sampled the estuary at over 90 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.
