On October 20, Class VII traveled to Fort Washington Park in Manhattan to sample the Hudson River as part of a state-wide program called "A Day In the Life of the Hudson." They joined over 4,500 students spread across 80 different sampling sites extending from Albany to the New York Harbor to capture a single day "snapshot" of the river's chemical, physical, and biological properties. Students spent the day rotating through five stations to measure characteristics such as salinity, dissolved oxygen, fish diversity, tides, and currents. All of Class VII's findings will be incorporated into a 14-year dataset that scientists use to monitor the characteristics and health of the river over time. The trip gives students the opportunity to participate in citizen science, collaborate with students across the state, and learn more about one of New York City's essential ecosystems.
