One of the best ways for biologists to learn about marine life is to tag along for the ride -- to plunge into the ocean depths, or travel on a migration that may cover thousands of miles. Since it’s hard to know how many sandwiches to pack for such a trip, though, scientists use proxies: satellite trackers, video cameras, and other devices.

Shortly after sea turtles hatch and enter the waves, they vanish from sight for the next two to ten years. Scientists often call these the “lost years” because no one is sure where the turtle toddlers go during this time. Until recently, many marine scientists believed the young turtles ride the waves until they gain the strength or navigation skills to actively swim. But scientists wanted to find out for sure, especially since sea turtles are endangered. Knowing where they are going and how they are getting there might make it easier to protect them.
