Nantucket Maria Mitchell Association Nantucket Harbor Water-Quality Monitoring Buoy Joins Regional Coastal Observing Network
NANTUCKET, MA— The Maria Mitchell Association’s (MMA’s) Nantucket Harbor water-quality monitoring buoy is now part of the Northeastern Regional Association of Coastal Ocean Observing Systems, known as NERACOOS. NERACOOS is one of eleven regional associations that make up the U.S. Integrated Ocean Observing System, or IOOS, NOAA’s national ocean-observing network for gathering and sharing ocean, coastal, and Great Lakes data.
This connection means that real-time data from Nantucket Harbor are no longer held only within a local monitoring program. They are now available through the NERACOOS Mariners Dashboard, where scientists, resource managers, educators, mariners, and the public can view Nantucket Harbor conditions alongside other coastal observing sites from Long Island Sound through the Gulf of Maine.
The monitoring buoy carries a suite of sensors that track changing conditions such as temperature, oxygen, acidity, nutrients, and underwater light. These measurements show what eelgrass, bay scallops, and other marine organisms are actually experiencing over time.
“This is an important step because Nantucket Harbor is now part of a larger coastal observing system,” said Dr. Betsy Sherman, the Maria Mitchell Association’s Senior Marine Science Advisor. “Our data can be compared with data from other sites, used in regional analyses, and placed in a broader environmental context. We are not just looking at Nantucket Harbor in isolation.”
The Nantucket Harbor buoy project has been supported by the Great Harbor Yacht Club Foundation, whose early investment helped make continuous water-quality monitoring in Nantucket Harbor possible. Additional support has been provided by the Remain Nantucket Fund at the Community Foundation for Nantucket, the Osceola Foundation, the Sociable Weaver Foundation, and through collaboration with the Town of Nantucket Harbormaster.
The timing is especially relevant for coastal communities because NERACOOS is also leading the newly funded NSF Seafood Engine in New England, a regional effort focused on strengthening fisheries, aquaculture, seafood technology, and coastal economies.
For an island community facing changes in water quality, habitat, fisheries, and climate, joining this regional network strengthens the scientific foundation for understanding and protecting Nantucket Harbor.
The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages.
