Monday marks one year since the satellite transmitter on Mary Lee, the great white shark who made a habit of visiting the Jersey Shore, was last detected.

Her last known location: Beach Haven, where she surfaced long enough for a signal to be sent from the tag on her dorsal fin at 6:54 a.m. June 17, 2017.

After that? The battery on the tag is believed to have died. Nonetheless, her spirit lives on in social media, where old posts continue to surface inciting her followers to believe her tag is sending messages anew.

Meanwhile, there are other tagged great white sharks "pinging" on the Jersey coast.

Beach Haven was visited by a great white shark this month named Amy. She surfaced five times on June 2 with little to no public attention.

"She's a 9-foot white shark tagged off South Carolina last December as part of the Massachusetts Shark Research Program's movement study," said John Chisholm, a biologist with the Massachusetts Division of Marine Fisheries.

Researchers are using tags to gather data on the movement of great white sharks, which have long been a mystery to scientists, in the Western Atlantic Ocean.

Chris Fisher, the founder of OCEARCH and the person who tagged Mary Lee in September 2012, said 1,300-pound Hilton, an adult male great white shark, and Savannah, an immature female great white, could both be off the Jersey coast soon.

"She's (Savannah) moving with some purpose and probably making her way back up to where she was in August," said Fisher, who is gathering data about microplastic in the Gulf Stream.

OCEARCH is a non-profit research group that collects data on several species of sharks.

Savannah migrated from the southeast to Nova Scotia last year, following her ideal water temps and food sources. She last surfaced in North Carolina on June 10.

It may be some time before another shark comes along and grabs the public's imagination as much as Mary Lee did — without involving an attack on a human.

Mary Lee was a mature female that measured 16-feet long and weighed 3,456 pounds when she was tagged near Cape Cod, Massachusetts, six years ago. She could be much bigger now, assuming she is still alive.

Mary Lee's migration route, which brought her to New Jersey waters every spring in 2015, 2016 and 2017, was observed in real time by many via the OCEARCH's Global Shark Tracker. Her Twitter account had over 130,000 followers.

Few other great white sharks have awed people on as grand a scale as Mary Lee.

Fishing: Jersey Shore mako shark contests proceed with caution

"El Monstruo de Cojimer" was a great white shark captured off the coast of Cuba in the 1940s. It is often cited as the largest great white shark ever recorded. The shark allegedly weighed 7,100 pounds and measured 21 feet.

Books have been written on the 1916 shark attacks on the Jersey shore that killed four and left one injured. The first attack occurred in July 1916 at none other than Beach Haven.

And, of course, there is the fictional great white shark "Jaws," which may have created an irrational fear of sharks.

The great white's population in the Atlantic dwindled due to fishing pressure but is on the rebound because of prohibitions on taking sharks.

"I think it's the fear of the unknown that scares people about sharks," said Fisher. "Statistically speaking, if people were as irrational about other things more likely to kill them than sharks, they'd never leave their house."
