Whether at night in freezing temperature or by day, the Harbor SEALs get their water quality data. Entrusted by the EPA to monitor the dissolved oxygen, bacteria, and nutrients in the water, these Volunteer Citizen Scientists are adding pieces to the environmental puzzle surrounding Governors Island and the Upper Hudson River Estuary. With the data they’re collecting, the SEALs will provide answers to the following questions: 01) do the waters of the East River cross over to the west side of Governors Island, 02) do the waters of the Hudson cross over to the east side of Governors Island, and 03) is there a difference in the nutrient and bacteria load between the east and west sides of Governors Island and Lower Manhattan? These questions are important if we are to look for ideal localities in which to re-populate oysters and other species. Stay tuned for more Harbor SEALs updates in the coming months.

This weekend, the Harbor SEALs trekked up to Black Rock Forest in Cornwall, New York to complete a one day ecology workshop sponsored by a Toyota Grant. We monitored the physical-chemical parameters of Cascade Brook and determined the health of this pristine ecosystem. With chemical and biological sampling gear in hand, we took a roller coaster-type ride up to the Brook on pick up trucks and got to work early Saturday morning. The SEALs team were able to determine that, although the Brook’s waters are pristine, it’s not immune to the effects of acid rain. We found pH values of around 5 to 6 units. Surveying the vertebrates and macroinvertebrates, the SEALs determined that the Brook has Type II organisms that are semi-tolerant to pollutants and thus are experiencing some stress. It wasn’t all work though as the team celebrated Ameena’s 17th birthday, hiked up to one of the Forest’s peeks, played board games, and delightfully cooperated in preparing meals. Thanks Rebecca and all for a great time! (For more pictures, click here: IMAGO)

Ameena, a 12th grade Harbor SEAL, addressed the guests at the Environmental Protection Agency’s 40th Anniversary of the Clean Water Act. Together with a member of the NY Harbor School’s Scuba Program, they delivered an impressive message about the future of clean water. “We have a right to protect the water’s resources and have access to our natural heritage,” said Ameena. There’s a long way to go but a new generation of environmentalists waiting to play their part.

On October 13 the Harbor SEALs, in collaboration with NYC urban ecologists and students from other NYHS CTE programs, planted about 20 “tortillas” of eel grass off of a decaying Brooklyn pier. These “tortillas” are made of cut-out burlap about 10 to 12 inches in diameter with 10 Eel grass individuals woven between the material in a concentric pattern. The team set up 6 stations with between 3 and 4 “tortillas per station, detailed GPS points were taken of each station, sedimentation rate was measured, and water quality monitoring was performed. It was another great day of environmental and team work under the NYC sun. (For more information click here.)
