For the second year, Class VII traveled to Fort Washington Park in Manhattan to collect scientific data about the Hudson River. This trip is part of a state-run program called "A Day In The Life Of the Hudson," which has supported thousands of students as they collectively sample the Hudson River on a single day in October. Sites range from Troy, NY all the way down to New York Harbor. This large-scale sampling event provides scientists with a yearly data "snapshot" of the river, and contributes to a long-term dataset that tracks the river's chemical, physical, and biological properties. Students spent the day rotating through stations where they measured river characteristics such as salinity, dissolved oxygen, fish diversity, tides, and currents. The trip gives students the opportunity to participate in field science, collaborate with others by contributing to a community dataset, and learn about one of NYC's essential ecosystems.
