Some giant sheets of ice off the coast of Antarctica are disappearing like ice cubes being emptied from a stack of trays in your freezer. The first tray was emptied two decades ago, a second followed a few years later, and a third may go by the end of the decade.

These “trays” are parts of the Larsen Ice Shelf. It reaches into the Weddell Sea from a narrow finger of land that extends toward South America.

You might think the largest – and perhaps loudest – animal ever to roam the planet would not be hard to track. After all, blue whales can grow up to 100 feet long, weigh up to 200 tons and produce sounds that travel 1,000 miles. And yet, until recently, scientists had difficulty figuring out where these massive krill-eating creatures traveled. Now, a single female named Isabela has offered some clues.
