"Scientists....say the waters around Montauk Point as well as those as far north as Cape Cod and as far south as New Jersey have long been considered part of a regional white shark nursery."
Researchers confirm there's a great white shark 'nursery' off Long Island.

A privately funded great white shark research group has confirmed that the waters off Long Island's Montauk Point are a shark "nursery," a first in the study of great whites in the northwest Atlantic Ocean, the organization and other leading scientists say.
But the OCEARCH expedition, which wrapped up months of work in the region Friday, is generating more than just scientific intrigue as it works off New York’s Long Island and Nantucket Island, Mass.
The Park City, Utah-based organization has also been embroiled in a public spat with shark researchers in Massachusetts, who accuse OCEARCH of encroaching into state waters without a permit and possibly compromising the state's own white shark research with its tactics.
OCEARCH founder Chris Fischer maintains his team has legally remained in federal waters off Nantucket and that there's "no scientific basis" for the concerns over his team's methods, which include using fish chum to lure sharks, hooking them, and then lifting them out of the water to take samples and apply GPS monitoring devices.
"I'm saddened and shocked by the whole issue," Fischer said from Nantucket. "We're generating really priceless data. We're thrilled with what we've accomplished. We just didn't expect to take a beating along the way."
The nonprofit group, which operates largely on corporate funding, made headlines in late August after confirming evidence of a white shark nursery off Long Island's Montauk Point.
Robert Hueter, the OCEARCH expedition's chief scientist, said that the nine newborn sharks they tagged have largely remained in the area, bolstering the organization's claim that the waters are a "true nursery," where great whites spend the first year of their life, and possibly even where the sharks mate and give birth.
"The tracking confirms they're in fact hanging around this area, feeding and growing," he said.
Scientists not affiliated with the project say the waters around Montauk Point as well as those as far north as Cape Cod and as far south as New Jersey have long been considered part of a regional white shark nursery.
But the phenomenon hasn't been as well studied on the East Coast as it has along coastal California, Mexico, Australia and other white shark hot spots, acknowledges Christopher Lowe, director of the Shark Lab at Cal State Long Beach.
"It's not necessarily new, but it's new for there," he said. "It will be interesting data for sure. But it's not the invention of sliced bread, either."
Newborn white sharks, which are normally about 5 feet long and weigh about 50 pounds, aren't reared by their mothers and must immediately start to fend for themselves. That's why they're drawn to shallow, coastal areas where easily captured prey is plentiful and predators, like older sharks, are few, Lowe says.
Years of study on white shark nurseries in the Pacific suggest water temperature is also a factor for young sharks, Lowe added. He expects the Montauk Point newborns to begin moving to warmer southern waters as winter approaches.
Gregory Skomal, a leading Massachusetts shark biologist who is among those raising concerns about OCEARCH's work off Nantucket, cautioned that it's too early to conclude that the area off Montauk Point is a birthing or mating site for white sharks.
The powerful predators have never been documented mating or giving birth, and sharks in general have been known to travel great distances in their first year, he says.
Hueter, who also serves as director of the Center for Shark Research at Mote Marine Laboratory and Aquarium in Sarasota, Fla., says the OCEARCH team will be returning to the northwest Atlantic in the coming years to continue studying newborn and mature white sharks.
"The stuff we're doing is groundbreaking," he said. "It simply hasn't been done out here."
