Image of The Day caption:
Biologist Peter Tyack (left) and senior engineer Mark Johnson have been working together to study whale behavior using Johnson's D-tag to record whale movements, depth, and sounds on dives. The tags are harmlessly suctioned on to the skin of whales for several days. Once they fall off and float to the surface, Johnson and colleagues take the tags back to the lab to read the story of the whales' dives?from their swimming behavior to the kinds of vocalizations they use while foraging.
