Crittercam on Gulf of California Green Turtles V: Surfacing Event

Many theories have been postulated as to how green turtles migrate around the worlds oceans, the most common of which (and the one with the most data) is that turtles use magnetic orientation to move around. However, in this and other surfacing videos from the Bahia de los Angeles foraging area, it appears that turtles may in fact be using visual cues to navigate within this coastal foraging area. Note the islands in the background. (In numerous videos, turtles are seen rotating at the surface until an island comes into view, at which time they dive again in the direction of the last-seen island)
