A Second Chance.

The Mission of the Marine Mammal Alliance Nantucket is to monitor, rescue and protect marine mammals on Nantucket, advocate for their well-being, and educate the public.

Making a difference.

Marine Mammal Alliance Nantucket is an all-volunteer non-profit organization, formed in cooperation with NOAA Fisheries to monitor, protect and assist marine mammals around Nantucket, Muskeget and Tuckernuck islands. Our team is here to advise and educate the public on what is normal behavior for marine mammals and what needs to be reported for help. We respond and disentangle pinnipeds from fishing gear, escort stranded cetaceans to safer waters and deliver injured or ill animals to rehab when necessary. Through outreach, education, collaboration and advocacy, we strive to make a difference.

Raising Awareness.

Global warming is causing marine life to change their migration patterns and habits. These changes put them on a direct path toward increased human interaction. Ship strikes have become commonplace as have seals and whales entangled in fishing gear. Seabirds, fish and mammals are ingesting fatal quantities of plastics; whales, dolphins and turtles are being found far off course resulting in mass strandings and beaches littered with cold stunned Mola mola and turtles. Marine life depends on our stewardship. As Greta Thunberg said, “Our house is burning!”


All of us are connected to the ocean, no matter where we live, and the health of her inhabitants is paramount to a healthy ocean ecosystem.

“If you protect the ocean, you protect yourself.”
