MMA Ocean Studies students Nat Cady and Nora Spratt are continuing the Year-Round Monitoring of Plankton in Penobscot Bay this summer!
This project is supported by the Maine Coastal and Marine Climate Fund and has guidance from Drs. Whittaker, Whitney, and Baer. Collaborators also include the Hurricane Island Center for Science and Leadership. The project’s data will provide insight into the impact of climate change experienced in the Penobscot Bay as well as monitor the ecosystem’s health.
To do this, Nat and Nora will use three oceanographic monitoring buoys paired with phytoplankton net tow sampling. MMA’s buoy, SCOOT, is located in Smith Cove, Castine, with Hurricane Island’s buoys located off the coast of Hurricane Island and Islesboro.
Each buoy has continuous data collection for salinity, temperature, depth, turbidity, dissolved oxygen, and the speed and direction of the ocean current. You can view this data in real-time via the website: https://mainemaritime.edu/penobscot-bay-plankton-monitoring/.
Phytoplankton net tows will be used to collect samples at the three buoy locations to then be processed in the MMA lab. Here, the FlowCam will be used to identify and categorize the phytoplankton species via image cytometry. These results will be available for public use on the website.
Weekly phytoplankton sampling at the buoy locations as well as buoy maintenance will occur on Thursdays throughout the summer, and monthly into the fall and winter - so stay tuned!
Pictured above is the deployment of MMA’s buoy “SCOOT” (Smith Cove Ocean Observation Tool) last week. Also seen are some favorite FlowCam images from samples collected at the MMA waterfront.
Nat and Nora will serve as FlowCam technicians and share their knowledge with Hurricane Island educational programs. They will also collect phytoplankton samples, analyze data, and perform buoy maintenance.
