Pictures: Baby Gulf Turtles Released Into Atlantic

The largest sea turtle species, the leatherback sea turtle (above, a female laying eggs in Costa Rica) is one of four sea turtle species that nest on Gulf of Mexico beaches.

Each summer, under the cover of night, female sea turtles climb onto beaches, dig holes with their flippers, deposit clutches of eggs, and return to Gulf waters.

About two months later, the hatchlings break out of the eggs, pop out of the sand, and make a quick scramble back to the Gulf to continue the life cycle.

The U.S. effort to relocate the sea turtle eggs—such as these removed from a nest in Alabama's Bon Secour National Wildlife Refuge on June 27—hinges on an understanding of the turtles' internal magnetic "maps," Hoggard said.

These maps—apparently "tuned" to Gulf beaches during incubation—should point the animals back to their native Gulf waters, even with the entire Florida Peninsula in their way, he said.

But he admits the massive sea turtle rescue operation is "uncharted territory" and could fail. "We can't afford to lose a generation of them," he said. "That's what gnaws at your stomach."

In addition to direct contact with oil, turtles and their eggs could be harmed by nighttime oil-spill cleanup operations, according to a statement by the Deepwater Horizon Joint Information Center.

For instance, bright lights, heavy machinery, and foot traffic may all disturb or injure nesting sea turtles. And hatchlings that use the moon as a compass may be disoriented by lights from cleanup crews.

Turtles in Waiting

The first group of the excavated Gulf sea turtle hatchlings are pictured recently in a Kennedy Space Center warehouse before being released into the Atlantic Ocean off eastern Florida.

The eggs—which take about 60 days to hatch—were allowed to incubate for 50 days in their native nests and spent the remaining 10 in a temperature-controlled warehouse.

Into the Wild

Scientists release Gulf of Mexico sea turtle hatchlings onto the beaches of Cape Canaveral, Florida, in a recent picture.

Most of the released babies are loggerhead sea turtles, though some could also be Kemp's ridley sea turtles, leatherback sea turtles, and green sea turtles, U.S. Fish and Wildlife Service national sea turtle coordinator Sandy MacPherson said in a statement.

Intrepid Turtles

The first Gulf sea turtle hatchlings enter the Atlantic Ocean in early summer 2010.

It may be 15 years before these hatchlings mature and return to Gulf waters to nest themselves, Hoggard said—if they do at all.

"We're giving up a whole generation of turtles," he said, "with the hopes that they'll come back."
