Whereas a sea turtle could also be afforded safety by the armor of its shell, they produce other struggles to deal with. As reptiles, they’re unable to intently regulate their physique temperatures like different mammals. Since their physique temperature is intently associated to the surroundings, if the water temperature dips under 50 F, sea turtles are prone to changing into cold-stunned.
Such was the case with 24 turtles rescued from Cape Cod seashores by Mass Audubon’s Wellfleet Bay Wildlife Sanctuary throughout a cold-stunning occasion, which started in November 2022 and went into January 2023. The turtles have been simply launched again into the wild.

“Chilly-stunned turtles grow to be torpid and are ultimately unable to swim, inflicting them to drift on the floor. Wind and/or tides could wash them ashore,” explains the Nationwide Oceanic and Atmospheric Administration (NOAA). “If temperatures stay low or turtles will not be rescued, they’ll develop secondary well being issues or die. Tons of and even hundreds of sea turtles might be affected by cold-stunning occasions.”
Chilly-stunning can occur anyplace with excessive chilly snaps however usually occurs in a lot of locations, together with Cape Cod Bay in Massachusetts. (Different areas embrace Lengthy Island Sound, New York; Pamlico Sound, North Carolina; Mosquito Lagoon and surrounding areas of the Indian River Lagoon, Florida; St. Joseph Bay, Florida; and bays statewide in Texas (together with Corpus Christi Bay, Matagorda Bay, Higher/Decrease Laguna Madre.)
Fortunately for the Cape Cod turtles, Mass Audubon steps as much as the duty with all fingers on deck throughout stranding circumstances. On twice-daily seashore patrols, greater than 170 skilled volunteers search the shore throughout stranding circumstances, “generally in the course of the night time, often in uncomfortable circumstances.” Within the 2022 season, greater than 70% of the ocean turtles retrieved from bay seashores have been alive. As soon as the turtles are processed on the Sanctuary, volunteers drive the turtles to the New England Aquarium for rehab.
The batch of launched turtles included 23 Kemp’s ridley turtles—a critically endangered species—and one inexperienced sea turtle. Biologists from the Aquarium drove the 24 turtles to the nice and cozy springtime waters of Fort Fisher, North Carolina, for the discharge.
“That is the most effective time of the yr for us. Getting the turtles again to their ocean house is why we do that, in hopes that every certainly one of these turtles helps their inhabitants bounce again from the potential of extinction,” stated Adam Kennedy, Director of Rescue and Rehabilitation.
The turtles spent months on the Aquarium’s Sea Turtle Hospital in Quincy, Massachusetts, in therapy for circumstances starting from pneumonia and dehydration to bone fractures. After veterinarians cleared the group of turtles to return to the ocean, the Aquarium organized floor transport south. The automobiles have been climate-controlled to match the temperature of the vacation spot waters for simpler acclimation.

“The vast majority of the cold-stunned sea turtles that come to our hospital have a poor prognosis, however as they progress of their rehabilitation, you see them actually begin to get their spark again,” stated Rescue Biologist Alessia Brugnara, who led the transport. “Working with these turtles from the second they arrive in off the frigid Cape Cod seashores, and seeing them swim away within the ocean, provides my job objective.”
In response to the Aquarium, they handled a complete of 518 turtles over the course of the 2022 season.
The NOAA notes that cold-stunning occasions have been documented for the reason that late 1800s. In Massachusetts, the variety of annual cold-stunned sea turtle strandings varies per yr however has been on a gradual rise, rising from round 50 in 2000 to about 900 in 2022—making it the third-busiest season on report. Scientists have predicted that by 2031, these occasions will convey hundreds of sea turtles to our shores yearly. As NOAA confirms, “current analysis within the northeastern U.S. means that warming sea temperature could also be influencing sea turtle actions in a manner that will increase the possibilities of cold-stunning.”
