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.)
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;)
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.
