There's a 1,000-pound great white shark swimming near the Jersey shore

A massive great white shark has been recorded swimming off the New Jersey shore.

The shark is named Ironbound, after the West Ironbound Island near Lunenburg, Nova Scotia, where it was first spotted. 

The creature is 12 feet, 4 inches long and weighs an estimated 998 pounds, according to OCEARCH, a nonprofit marine research group that provides open-source data about shark migration. 

Ironbound was first tagged on October 3, 2019, in the waters around Nova Scotia. As part of its data collection process, OCEARCH captures and fits sharks with an electronic tracker that pings whenever they break the ocean surface. 

Ironbound, migrating north, pinged in the waters off the coast of New Jersey about 10:30 p.m. on April 28. 

The large fish is likely around 20 years old, according to Bob Hueter, chief scientist at OCEARCH. 

Although formidable, Ironbound isn't the biggest shark the organization has encountered: Hueter said that OCEARCH has tagged great white sharks as long as 17.5 feet and as heavy as 4,000 pounds. 

"When we tagged him, he was impressive," Hueter said of the shark.
