BRIGANTINE - She's back.

Mary Lee, the 3,456-pound female great white shark whose movements are tracked online, has surfaced off the New Jersey shore.

The shark has traveled almost 20,000 miles since she was tagged with an electronic tracker off Cape Cod, Massachusetts, in 2012 by OCEARCH. The nonprofit ground researches sharks.

Mary Lee has been heading up the East Coast. She was off North and South Carolina last month.

By Friday morning, the tracker placed the 16-foot shark 10 to 15 miles off Brigantine.
