Cameras attached to a rare species of Antarctic whale are giving scientists an unprecedented view of how the whales survive in their sea ice habitat.
In a recent study, scientists attached tags to 30 Antarctic minke whales, a small and little-known species of baleen whale, to better understand the animals’ sea ice environment.
The tags, clinging to the animals’ backs with suction cups, recorded video and motion data for 24 to 48 hours.
Some of that footage is shown here.
Each time the whales surfaced, the researchers could calculate from the video how much sea ice was present, providing clues as to how the amount and type of sea ice influenced the whales’ behavior.
Previous research had relied on satellite images to study the whales’ habitat, but scientists needed to get closer to truly understand how these creatures were moving through their sea ice environment.
While the research is still ongoing, preliminary data from the whale cams are already revealing surprising results, according to the researchers.
From the six tags analyzed so far, the researchers saw whales were spending 52 percent of their time in open water compared to just 15 percent in water with high concentrations of sea ice.
As the tagged minke whales swam and dived under the ice, the scientists also learned new things about the cryptic species and its behavior.
The piggybacking cameras allowed scientists a whale’s-eye view of a day in the life of an Antarctic minke—its feeding habits, social life, and where it spent the most time.
As Antarctic sea ice continues to shrink under climate change, understanding its importance for the whales will be crucial for protecting them, according to the researchers.
