Loggerheads' Magnetic Navigation

When Loggerhead Turtles leave their nests in Florida, they embark on an 8,000 mile migration across the Atlantic and back. Scientists have now discovered that the turtles keep to their path and in warmer, food-filled waters, by responding to magnetic fields--almost like a global positioning system. Ken Lohmann headed up the research...

As Loggerhead Turtles take five years or more to swim across the Atlantic and back, they're using the earth's magnetic field to determine their location and stay in warmer water. That's the finding of new research from a team headed by turtle researcher Ken Lohmann...

New research shows that Loggerhead turtles use the earth's magnetic field to help determine where they are in the open ocean, during an 8,000 mile migration across the Atlantic and back. Turtle research Ken Lohmann says Loggerheads make good use of their unusual positioning and navigational abilities, keeping them in a current called the North Atlantic Gyre...

There's new research indicating that Loggerhead turtles are able to use the earth's magnetic field to not only determine the direction they're swimming, but also to figure out where they are in the open ocean. The findings come from a turtle research team led by Ken Lohmann...

New research findings that Loggerhead turtles are born with the ability to magnetically navigate their migration poses an unusual challenge for conservation efforts. Ken Lohmann led the team that found the turtles' Global Positioning ability...
