Saving Gretel The Great White Shark

This presentation celebrates the 15th anniversary of Gretel, a 14 foot female white shark that entered a shallow estuary in Massachusetts on September 21, 2004. She was tagged immediately, but remained trapped in the pond for two weeks. As she progressively weakened, her fate remained in the hands of a group of biologists. Gretel was the first white shark tagged with satellite-based technology in the North Atlantic and, in many ways, an omen of what was to come.
