Mack the harp seal swims free!

Posted on March 20, 2018

On Sunday, March 18, 2018, the Seacoast Science Center Marine Mammal Rescue Team (MMRT) released Mack the harp seal back into the wild. A “poster-child of a healthy harp seal,” Mack was fit, fat, and ready for his swim back to the Arctic after four weeks of care at the National Marine Life Center. Nearly 1,000 people witnessed the joyous event, held on the same beach from which he was rescued: Hampton Beach State Park in Hampton, NH.

Mack is only the second seal rescued by MMRT to be released back here in NH. While most seals are released near rehab facilities, Mack was the perfect candidate to be brought back to NH so he could not only help spread awareness of the important work we do, but also give our community the opportunity to celebrate the success of our efforts. Special thanks goes to our partners who helped us make it all possible: National Marine Life Center and New Hampshire State Parks.

We rely on our community for support to help us stay ready to respond to all calls of any marine mammals that strand on the shore, dead or alive. Please donate today.
