For Educators
HRECOS data can connect your students to the estuary in their backyard and help you keep pace with Next Generation standards for science education. Together with educators like you, we’ve developed lesson plans and other tools to support your projects and programs. You also can use our real-time data and historic data sets to develop activities and programs of your own.
Wading into the Hudson
Wading into the Hudson is an introduction to the Hudson River estuary essentials, including tides, currents, salinity, and climate change. And its all taught through interpreting graphs and images. Slides include notes and instructions for teachers.
A Virtual Checkup of a River’s Vitals: Using Remotely Sensed Data
Updated in April 2024! This presentation goes deeper into river parameters with HRECOS. By using case studies and curated HRECOS graphs, students can investigate weather, water chemistry, and biological phenomena. Notes for each slide provide background content and instructions for teachers.

For Researchers
HRECOS monitors and documents baseline weather and water quality conditions, tracking long-tern change and short-term variability. An analysis of this data can provide a solid foundation for detecting change caused by human-influenced and natural events.
You can use our data and associated products for field-testing and calibration/verification of models. It also can support summary statistics, hypothesis testing, and observations to describe novel phenomena and enhance understanding of the Hudson River system.
As part of the National Estuarine Research Reserve’s System-Wide Monitoring Program (SWMP), Hudson River Reserve has maintained two of their HRECOS stations for several decades (Tivoli Bays since 1995). Compiled for the past several decades, this data set on parameters like temperature, salinity, and dissolved oxygen, allows for year to year comparison. The Reserve provides annual analysis of this data their SWMP Status Reports. They plan to update these Status Reports each year when new data becomes available, so check back for updated versions!
