Every morning, Kenny Gordon, the 55-year-old maintenance manager at the Blue Water Point Motel and Marina, watches guests head off for the beach on this North Carolina vacation island. But if they ask him, he tells them to think twice before getting in the ocean.

It’s no secret to this island’s longtime visitors and residents that many varieties of shark patrol the turgid waters, just as they do along nearly every ocean coastline on the planet. Fishermen flock to the 20-square-mile barrier island near the North Carolina-South Carolina border each summer to catch, sell, mount and eat the wide range of shark species that frequent the area, including bull, tiger, hammerhead, nurse, sand and ~~blackfin.~~ A towering great white – in a plastic, life-sized form – has hung tail-up from the sign of a local surf shop for more than a decade, in homage to the great killer that is occasionally spotted nearby.

But this weekend, thanks to a recent, bloody turn of events, the deep association between the island and its wildlife will be weighing more heavily than usual on visitors’ minds, even as expected annual crowds flock to its sandy beachgrass-covered dunes to celebrate Independence Day.

On 14 June, here on Oak Island, a shark ripped into a 12-year-old girl who was standing waist-deep in the water. Ninety minutes later, and two miles down the beach, the same thing happened to a 16-year-old boy. Both youths survived the attacks thanks to quick medical attention on the beach and helicopter transports to a regional hospital. Each eventually lost an arm.

The attacks were the most vicious in what appears, to untrained observers at least, to be a spike in shark attacks along this southern state’s beaches. Since 11 June, there have been at least seven incidents of sharks biting humans on the North Carolina coast.

“The first I saw of it was when it was biting up my left arm, kind of. Then it got that off, eventually, and it swam,” the 16-year-old victim, Hunter Treschel, said in a video released by New Hanover regional medical center, where he has been recovering from his injuries.	“The first I saw of it was when it was biting up my left arm, kind of.

Shark attacks on humans remain exceptionally rare. The University of Florida’s International Shark Attack File confirmed 72 unprovoked shark attacks in the entire world last year (33 more were considered to have been provoked by victims; in a handful of others, sharks tried to take a bite out of a boat). By comparison, in 2013, nearly 33,000 people died in car crashes in the US alone. Once you have survived the drive to the beach, you are several orders of magnitude more likely to die from falling, drowning, over-exposure to the sun, or getting hit by lightning or the fireworks you brought with you than you are to be killed by a shark.

That’s even more impressive when you consider how common both sharks and swimmers are. Gordon is right, according to the experts: there probably are thousands of sharks off the North Carolina coast during the summer, many near the shore. North Carolina state tourism officials estimate that there are about six million visitors to its beaches every year.

“The idea of going to the beach and having a good time and something tries to eat you – that’s exciting stuff,” said Dr Lawrence B Cahoon, a professor of biology and marine biology at the University of North Carolina at Wilmington. He noted that movie theaters across the US recently screened a special 40th anniversary edition of Jaws – Steven Spielberg’s masterpiece, built, coincidentally, around a Fourth of July weekend. Scientists say the movie put a durable bundle of myths about killer sharks in generations of moviegoers’ heads.	“The idea of going to the beach and having a good time and something tries to eat you – that’s exciting stuff,” said Dr Lawrence B Cahoon, a professor of biology and marine biology at the University of North Carolina at Wilmington.

The 14 June incidents on Oak Island raised more alarm than usual because, three days before a shark had bitten a 13-year-old girl’s boogie board on Ocean Isle, nine miles to the west. The teen’s injuries were minor and the incident received passing attention at the time. But with the Oak Island attacks now pointing to a possible trend, North Carolina media went on alert for more. And more came.	The 14 June incidents on Oak Island raised more alarm than usual because, three days before a shark had bitten a 13-year-old girl’s boogie board on Ocean Isle, nine miles to the west.

The seven attacks recorded in North Carolina are the most the International Shark Attack File had recorded in the state in a single year going back to 1935, said Lindsay French, a program assistant who helps maintain the database.

Shark experts and marine biologists admit they have no idea. It’s impossible, many note, to even to say if a significant event is occurring in the state.

“We don’t know right now, until we look at the long-term trend data,” said Dr John Carlson of the National Oceanic and Atmospheric Administration Fisheries Lab. “It could just be the summer weather. Maybe twice as many tourists are going to the beach in North Carolina.”	“We don’t know right now, until we look at the long-term trend data,” said Dr John Carlson of the National Oceanic and Atmospheric Administration Fisheries Lab. “It could just be the summer weather.

Some shark experts and observers have theorized that warmer waters, a local drought that has caused higher salinity in the water – which sharks and their prey both favor, an active sea turtle nesting season, fishing on piers near beaches or some combination of all of those factors might be making certain sharks more aggressive in North Carolina.

Some kinds of sharks can get more agitated when water temperatures exceed 80F (27C), said Dr Frank J Schwartz, who has studied the creatures for nearly five decades at the University of North Carolina at Chapel Hill’s Institute of Marine Sciences – raising the possibility that global warming could lead to marginal increases in shark attacks over time.

Some Oak Islanders speculated that shark fishermen attracting the animals to the coast with their oily bait, or by “chumming,” spreading fish parts into the water, were provoking the attacks. Still, North Carolina state fishing authorities declined to enforce a shark-fishing ban on Oak Island through the busy 4 July weekend.

“We’re asking fishermen to, you know, be cognizant of where they’re fishing, not to be fishing on crowded swimming beaches,” Patricia Smith, public information officer for the North Carolina division of marine fisheries, told a local news station.	“We’re asking fishermen to, you know, be cognizant of where they’re fishing, not to be fishing on crowded swimming beaches,” Patricia Smith, public information officer for the North Carolina division of marine fisheries, told a local news station.
Nationally, the numbers are less remarkable, casting doubt on whether there is a larger trend at play. There have been 25 shark attacks in the US this year – one fatal, in Hawaii. That is roughly on track to match 2014’s US total of 52. (Florida, with its larger numbers of tourists and year-round beaches, leads the national count, as always, with 11 attacks so far this year. The Sunshine State saw 28 shark attacks in 2014.)	Nationally, the numbers are less remarkable, casting doubt on whether there is a larger trend at play.

Historical comparisons are also hard to make because there were fewer people travelling to beaches in the past. Counting attacks has also long been an imprecise science – for instance, fewer shark attacks were reported before the age of mass communications and social media, French said.

The attacks reported so far in North Carolina have been clustered in two areas: the north-eastern Outer Banks, where three of the attacks have occurred; and the state’s southernmost coast, including Oak Island, which lies more than 100 miles away. There is no proof yet that any are connected. Crucially, no one even knows what kinds of sharks have been involved. Many experts suggest a mix of sharks of different sizes and temperaments, as the incidents have ranged from minor injuries to aggressive attacks resulting in multiple life-threatening injuries.

Researchers will eventually try to determine what kind of sharks were involved using measurements of the bites and data on what kinds of sharks were in the areas at the time that the bites occurred.

Generally speaking, the experts say, sharks try hard to avoid humans. To them, we’re dangerous, alien creatures that presumably don’t taste very good. When bites do occur, it is often because a shark has mistaken a person for another animal. To that end, the scientists recommended avoiding wearing ankle jewelry that could flash and be mistaken for a fish. Kids on boogie boards can also be mistaken for sea turtles – which may have been the case in the first recent attack on Ocean Isle.

Several of the experts recommended swimming in groups. That’s good advice in general, they noted, to cope with dangers far more prevalent than sharks, such as rip currents.

Many did agree with a commonly shared piece of advice – that hitting a shark on the nose will temporarily stun it, possibly creating time to get away. But opportunities to do so are even more rare than shark attacks. As in Treschel’s case, most shark attack victims never see the predator coming. If a powerful shark is truly determined to kill, it will be very hard to deter.
