Marine Ecology field trip
Upper School students in Marine Ecology visited nearby Edith Read Wildlife Sanctuary during a low tide to conduct a self-designed study on the invasive Asian Shore Crab (Hemigrapsus sanguineus).  Students used quadrats to randomly sample the crab populations in the upper, middle, and lower intertidal zones.  In addition to counting the crabs in each sample, students measured the length and identified the gender of each crab.  Students will use the data collected to write a detailed report of their findings.

In addition to studying the Asian Shore Crab, students used a plankton net to obtain a sample that would later be analyzed under a microscope to identify species of both phytoplankton and zooplankton.  

All of the data from the trip, including weather and water quality, will be inputted into the Long Island Sound Biodiversity Database.  Several local organizations participate in this ongoing project with an ultimate goal of identifying trends in Long Island Sound.  For more information on the biodiversity database, please see:
