So far this year the 10th grade Marine Biology Research students have done a great job of working together to produce exceptional results. Putting together Aquatic Ecosystem Models, they’ve begun to learn the basics of water chemistry, physics, and ecology. From jump starting the nitrification cycle in their Models by adding ammonium chloride and nitrifying bacteria to adding terrestrial plants for nitrate removal, these future environmental scientists are learning what it takes to keep an ecosystem healthy from the bottom up. Once these students have mastered keeping their Ecosystems healthy they’ll start formulating projects around the Hudson River Estuary to apply their skills to the real world. Continue here.

Harbor SEALs @ Black Rock Forest
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)

Harbor SEALs at the 40th Anniversary of the Clean Water Act
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.

Repopulating the Hudson River Estuary with Eel Grass
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.)
SEALs TNC LEAF Graduation 2012
Last night three of our Harbor SEALs and one other NYHS student graduated from The Nature Conservancy’s LEAF Program. The ceremony was held at the Marriott Hotel on West Street in downtown Manhattan. The highlight of the night was listening to the kids’ stories of how working to conserve the great outdoors changed their lives. We heard tales of students doing their laundry in haunted basements, walking miles in the dark of night to take out the garbage, taking down fences to create biological corridors, and going to drive-in movies for the first time. The audience, comprised in part by New York Trustees, reminisced of their younger years and could only be pleased of hearing about the important work and wonderful experiences lived. Well done SEALs! You are the hope of our planet…
Harbor SEALs Launch First Workshop
We launched our first workshop of the school year today. We had a great turn out as students from grades 10 through 12 came together to learn more about our great Harbor and the Hudson River Watershed. Using the Black Rock Forest Virtual Lab units that the director helped to create, the students embarked in a virtual tour of the Hudson River starting with a map to help define the term watershed. We then worked our way through the Troy Dam, stopped to inspect the recuperating populations of Atlantic Sturgeon, and headed down to Norrie Point to discuss the invasive water chestnut.
At one point we got into a heated debate on the ethics of Catch and Release: Should humans have the right to partake in leisurely activities at the cost of other animals’ lives or well-being. The debate got very heated but in the end, we understood that individuals can have different levels of ideals when it comes to what’s socially acceptable. But most importantly, we all agree that nature needs to come first if we humans want to “keep on keeping on.”
PD. As is our tradition, we took a serious shot of the kids (above figure) but also a wacky one. To see the latter, navigate over to the IMAGO tab above. Enjoy;)
Harbor SEALs Come to Life!
On September 22nd the Harbor SEALs embarked on their first expedition of the 2012 school year to monitor the relative mass of plankton and plastic in the Hudson River Estuary. Aboard the NOMAD, the SEALs monitored physical-chemical parameters of the water and practiced sampling protocols in order to deploy a 20 foot plankton net with manta (Marvin) into the waters south of the Verrazano Narrows Bridge.
