Scientists are diving deep off the coast of Antarctica to help protect whale feeding areas.
But they're not jumping into the frigid Southern Ocean themselves. Instead, a team of researchers has attached non-invasive sensors and cameras to the backs of humpback and minke whales.
The project , supported by World Wildlife Fund's Australia office, has gathered a bounty of information so far, including when, where, and how whales eat krill; what their social lives are like; and how they're able to blow through sea ice so they can breathe.
