The Harbor SEALs have been hard at work this season recovering marine debris from the rip rap surrounding Governor’s Island, NYC for the Hudson River Foundation. Student interns and volunteers from the New York Harbor School have been managing this project since September of 2021. The team is broken up into four work groups 01) Data Analysis, 02) Resource Recovery, 03) Communications, and 04) Water Quality. The team submitted a proposal to ConEdison and were awarded a grant to purchase the equipment necessary to safely scale the rip rap and recover NYC’s pervasive debris. Large garbage bags full of plastic bottles, boat line, dock Styrofoam, sports balls of all types, and mini alcohol bottles dot and span the rip rap. But by far the most interesting of findings have been a message in a bottle and a glamping tent.
After spending much of the Fall planning and writing the proposal, ordering materials, testing the safety equipment, and undergoing practicing trials, the SEALs began recovering debris in January. The Data Analysis group began defining categories of debris, creating data tables, and online forms. They then proceeded to classify the debris collected each sample day and weigh them by category. The Recovery team worked to perfect the methods for safely removing debris from underneath the rip rap and collected three geographically located quadrants to be able to determine the rate of debris replacement. Our communications team designed social media interfaces to disseminate our work products and reached out to our various stakeholders to coordinate field days. They also were in charge of writing the summary grant reports to ConEdison. Our Water Quality team began training in the measurement of Dissolved Oxygen in the sample site using the Modified Winkler Method. They also measured nutrients and other physical-chemical parameters. Finally, they began testing a drone with 3D deigned sampling devices to collect water samples from the Estuary.
Stay tuned for our publicly shared data and final report!
