HIGHLANDS, NJ — While it’s been three weeks since great whites Finn and Amagansett have surfaced long enough to allow for them to be tracked, another tagged shark has entered the waters off the coast of New Jersey.

Bruin, a young male, has been “pinged” about 30 miles off Highlands, traveling south from where he had been tagged on August 12 off Montauk, N.Y., by Ocearch’s Global Shark Tracker.

His location is in close proximity to where Finn last registered her last ping at 11:26 a.m. on September 18 and Amagansett at 10:30 p.m. on September 14. Both appeared to be following a northbound route at that time.

Shortly after being tagged on August 12 off Montauk, N.Y., Finn began traveling south and settled off the coast along Monmouth County on September 1, where she stayed before her latest move to go north.

After being tagged on August 20 also off Montauk, Amagansett followed a similar path but traveled farther south, circling around the waters off the Ocean County coast before making the pivot northbound.

When all three juvenile sharks were tagged by Ocearch researchers, Finn measured nearly 5 feet and weighed 79 pounds, and Amagansett came in at nearly 5½ feet and 92 pounds and Bruin at nearly 5½ feet and 101 pounds.

Meanwhile, Mary Lee — the 16-foot, 3,500-pound shark that became a social media sensation this spring with her travel adventures in the Atlantic Ocean off New Jersey — registered her last ping at 6:54 a.m. on June 17 about 10 miles off Long Beach Island.

Since Mary Lee was tagged off Cape Cod, Mass., on September 17, 2012, she has traveled up and down the East Coast — from Nova Scotia to the Turks and Caicos Islands — for a total of some 40,000 miles.

Despite her tracking silence, Mary Lee remains a social media star with a 129,000-member Twitter following, while Finn is followed by 931, Bruin by 921 and Amagansett’s by 821.

All four great white sharks are among dozens of apex predators throughout the world that have been tagged by Ocearch researchers with global positioning satellite (GPS) devices in order to track their movements to better understand their behaviors.

Ocearch registers a ping when the shark’s dorsal fin breaks through the water, transmitting a signal that provides an estimated location. The group then displays a marker on a Google Earth map indicating where the ping was received.
