Eglin Air Force Base biologist Kathy Gault (left) and Dave Seay (right), a contract biologist working with the USGS, hauled cold-stunned sea turtles to safety along the icy shore of Cape San Blas. Scientists and licensed volunteers walked the beaches and marshes, loading cold-stunned sea turtles into kayaks. Once full, kayaks could weigh more than 400 pounds and had to be dragged two to three...

When water temperatures drop below 50 degrees Fahrenheit (10 degrees Celsius), cold-blooded sea turtles, like this Kemp’s ridley, can become cold-stunned. They are unable to swim or even raise their heads out of the water to breathe, which can lead to drowning. Photo by Margaret Lamont, USGS
