Break Time

Seals like this one photographed during the Sea Ice Physics and Ecosystem Experiment (SIPEX-II) in Antarctica, depend on sea ice to survive. They hunt for food, such as fish and krill, under the ice, and use the ice surface for rest and to have their pups. During the expedition, WHOI researchers Clay Kunz and Peter Kimball deployed their lab’s autonomous underwater vehicle Jaguar to map the undersides of four sea ice floes, which will lead to a better understanding of how they form and change over time.
