The endangered sea turtles get trapped in the hook of Cape Cod as they head south, then suffer from hypothermia and exhaustion.

They should have banged a left at the Pilgrim Monument in Provincetown. Now the winds and tide wash them ashore from November through about mid-January.
Most are juveniles who have overstayed their welcome. They have been paralyzed by the decreasing temperature as the water temperature dips below 50 degrees in Cape Cod Bay.
If these turtles are not rescued, they will die.
On a recent Friday, with temperatures in the low 30s and winds gusting over 25 miles per hour, the experts at Mass Audubon predicted possible strandings.

And so the rescue mission begins.
At 6 a.m., the early dawn is just appearing. The beaches are dotted with clumps of dark seaweed. Aaron Gouveia, and his sons Will, 17, and Thomas, 10, patrol Corn Hill Beach.
Spotting turtles is hard, but this is not Gouveia’s first rodeo.
“All that seaweed piles up, and everything looks like a turtle in the dark,” says Gouveia, who is public relations director at Mass Audubon.
At First Encounter Beach, signs from the Mass Audubon’s Wellfleet Bay Wildlife Sanctuary give tips on rescuing a stunned sea turtle. The basic misconception by the public is to return them to the water.

The trio spread out and within 15 minutes, Gouveia sees something move near a clump that his youngest son has already passed. It turns out to be an exhausted green turtle raising a single flipper, just once, as if calling out for help.
Then it stops moving. When Gouveia picks it up, it moves again. Will quickly strips off his lined winter coat with the Patriots logo, a hand-me-down from his maternal grandfather, to give it some warmth.

Gouveia calls the Wellfleet Bay Wildlife Sanctuary 24 hour hotline (508-349-2615) for a possible pickup.
Normally when turtles are found, the sanctuary tells them to move the turtle above the high tide line, cover it with seaweed, and mark the spot so the sanctuary can find it.
But he’s told that today they’re swamped.
He hands it off to Thomas to carry and the 10-year-old is ecstatic.
Last year, Thomas found a Kemp’s ridley turtle and even named it “Mr. Ridley,” but it never showed signs of life. Earlier this month, his dad dismissed him from school early to go on patrol, but they got skunked.

This time, the turtle is coming back to life, to everyone’s delight. The more Thomas walks the more the turtle reacts.
“It was squirming all around. I was worried I was going to drop it because my arms were getting so tired. It was a really cool experience,” he says.
As the sun rises, they spot a Kemp’s ridley that wasn’t moving and had pink tinged skin, probably caused by exposure to the cold water.

Kemp’s ridley’s are critically endangered and the most rescued turtle on the Cape.
A few minutes later, another Kemp’s ridley is discovered, partially burrowed in the sand. Thomas gladly surrenders his coat.
They complete the patrol, three guys, shivering in sweat shirts. Like proud fathers, they each carry a turtle swaddled in their coats like newborn babies.

A team of 200 volunteers will comb Cape beaches until mid-January. At Audubon’s Wellfleet Sanctuary, biologist Michaela Wellman, weighs them and takes the temperature of the new arrivals.
The sanctuary has processed 463 turtles since November: 395 Kemp’s ridleys; 64 green; four loggerheads. As of Monday, 190 turtles had washed ashore since Thanksgiving, according to Audubon.
The most in one season was 1,241 in 2014. Thirty years ago, an entire season would be just 100 turtles. On this day, volunteers rescued 55.

Turtle strandings have increased for a couple of reasons. Conservation efforts have led to more female turtles nesting on beaches in the south. The Gulf of Maine, which includes Cape Cod Bay, is one of the fastest warming bodies of water. This could attract more turtles to feast on the local seafood buffet, and stay longer.
Global warming contributes to the increasing number of strandings. “Since it’s warmer up here, we get more turtles come up, so more get stuck,” says Wellman.
About 70 percent of the sea turtles that wash up are rehabilitated, according to Mass Audubon.
At the Wellfleet sanctuary, an eight-person staff works in 55-degree rooms to prevent the cold-blooded turtles from warming up too quickly.

The turtles are assigned a number, evaluated, and placed in a fitted used banana box, donated by local supermarkets.
Volunteers then drive them to New England Aquarium’s Sea Turtle Hospital in Quincy.

“It’s important to save these guys and help the planet,” she says.
She’s even driven several hundred pound loggerhead sea turtles that don’t fit in banana boxes.
“They’re usually so quiet because they’re stunned. They don’t move a lot.”
The rules of transport are strict. It should be quiet and cold.

Drivers are not allowed to play any music . No Jimmy Buffett singing “changes in latitude,” or even oldies like “Happy Together” by the Turtles.
“It must be totally silent. You can’t have the heat on. So, it’s December and I’ve got the windows open going up Route 3. People give you funny looks,” she says with a laugh.
