University of California researchers have attached cameras to 30 rare Antarctic minke whales to see how sea ice affects their behavior.

The tags, clinging to the animals’ backs with suction cups, recorded video and motion data for 24 to 48 hours. Each time the whales surfaced, the researchers could calculate from the video how much sea ice was present, providing clues on how it influenced the whales’ behavior.

Previous research has relied on satellite images to study the whales’ habitat. Read on.
