International consortium created to study the white shark

December 7, 2020 — Shark research groups and government agencies in the United States and Canada announced Tuesday the establishment of an organization that will unite over a dozen agencies to collaboratively study the white shark.

The New England White Shark Research Consortium joins organizations and universities in Massachusetts—such as the New England Aquarium and University of Massachusetts Dartmouth—with researchers in Maine, Rhode Island, New Hampshire, Arizona and Canada.

The group has two primary goals: advance researchers’ current understanding of the white shark, and enhance public education and safety within the region.

Gregory Skomal, the senior fisheries scientist for the Massachusetts Division of Marine Fisheries (which is a consortium member), said the fatal shark attack of a 63-year-old woman off the coast of Maine this summer prompted the creation of the consortium.

“It really pointed to a need for us to coordinate research here in New England,” Skomal said, noting many people were surprised by the location of the attack even though researchers knew white sharks are historically found in Maine waters.

New regional shark research consortium established

December 2, 2020 — The fatal great white shark attack on swimmer Julie Dimperio Holowach in July in Harpswell, Maine, caught many in the shark research community by surprise.

While it was known that some great whites do travel north into Canadian waters in the summer, there was little in the way of sightings, and just a smattering of attacks on seals.

Holowach was the only confirmed fatality from a shark attack in Maine history, according to Patrick Keliher, state Division of Marine Resources director. Cape Cod, with hundreds of great whites patrolling beaches and daily sightings in the summer months, has had two major attacks on swimmers and a fatal attack on a bodyboarder.

“The incident really did rattle the state of Maine, and justifiably,” said Gregory Skomal, Massachusetts Division of Marine Fisheries shark expert. “A lot of us doing work on white sharks reached out to assist.”

Great whites attracted by plentiful seal populations in Maine waters

July 29, 2020 — Monday’s fatal shark attack off Harpswell is the result of rebounding great white shark and seal populations along the Maine coast, experts say.

The attack on Julie Dimperio Holowach, 63, was the first fatal shark attack in the state’s history. A diver was attacked off Eastport in 2010, according to the Florida Museum’s International Shark Attack File, but he was not injured and fended off a porbeagle shark with his video camera.

Seal populations have grown since a 1972 law barred killing of marine mammals and white shark numbers have been rebounding for two decades as a result of a rule that said fishermen could no longer kill the fearsome predators, a shark expert based in Massachusetts said.

Gregory Skomal of the Massachusetts Division of Marine Fisheries dismissed speculation that warming water temperatures in the Gulf of Maine might be enticing more great whites to the state’s coastline.

He said the sharks always have been frequent visitors to Maine waters, but that growing seal populations might be drawing them closer to the shore. Seals are a favorite food of the great white, he said.

MASSACHUSETTS: Shark detection technology gets quiet rollout on Outer Cape

August 5, 2019 — With little fanfare, shark detection technology on Cape Cod took a small step forward last month off Newcomb Hollow Beach, the site of last year’s fatal shark attack on body boarder Arthur Medici.

Cape Cod and regional public safety officials have been hoping for years to employ a kind of souped-up version of what they already have, an acoustic receiver attached to a buoy that can not only detect signals from tagged great white sharks but relay an instantaneous alert to lifeguards and beach administrators.

One such device was deployed off Newcomb Hollow, state shark researcher Gregory Skomal said, and two more to be placed at Head of the Meadow Beach in Truro and at Nauset Beach in Orleans.

MASSACHUSETTS: Great White Shark Numbers Increasing On Cape Cod

May 26, 2017 — We’re getting close to that time of year, when the great white sharks make their annual visit to the waters of Cape Cod. Cape Cod is the only known aggregating site for white sharks in the North Atlantic.

According to the latest study by the Massachusetts Division of Marine Fisheries, the number of great white sharks vacationing there appears to be rising. That’s a public safety issue for towns, according to the state’s top shark expert.

Interview Highlights

On their survey of the numbers of great white sharks

“We are right in the middle of a 5-year population study … what I can tell you … is how many individuals we’ve tabulated year for the last couple of years. In 2016 for example, we identified 147 individual white sharks along the Eastern shoreline of Cape Cod. The year prior to that, it was 141 and the year prior to that in 2014, it was about 80. So we’re seeing that subtle increase from year to year. And as tempted as I am to say that it’s actually an increase in the population size, it’s more likely a shift in the distribution of sharks in response to the growing seal population.”

On how the seals are attracting sharks

“Most people don’t realize the interesting history of the seal populations on the Northeastern coast of the U.S. They had been all but drive to extinction a couple of hundred years ago. And now, with protection that was put in place in the early 1970s, we’ve seen the slow growth in the population that has now resulted in literally tens of thousands of seals along our coastline. And that has drawn the attention of one of their predators, the white shark.”

MASSACHUSETTS: Scientists take advantage of rare shark stranding in Orleans

ORLEANS — The corpse lay on its side as scientists honed knives on whetstones in preparation for the first cut.

But the scene at the town transfer station Monday wasn’t a ghoulish Halloween skit intended to frighten the knot of onlookers; it was a necropsy on a 12-foot-long great white shark that washed onto Nauset Beach on Sunday, dying in the sand.

The scientists were there in part to see if there was any obvious reason the 20-year-old male shark had washed ashore and died. But they also were collecting valuable specimens from an animal that can no longer legally be caught and killed, leaving researchers dependent on the rare instances when one washes up on the beach.

“We hate to have sharks strand because we like to have them in the water and healthy, but when they do we maximize what we could possibly learn from them,” said Gregory Skomal, lead shark scientist at the state Division of Marine Fisheries.

Researchers from his agency, the National Marine Fisheries Service, and University of Massachusetts Dartmouth’s School of Marine Science and Technology converged on the transfer station Monday morning to take advantage of the opportunity.
