Presented by National Geographic Society in partnership with Rolex. Sherman Basin is a sanctuary for wildlife north of the Arctic Circle, with waters that teem with fish and seals and tundra that supports caribou and musk oxen—a stark contrast to the inhospitable waters that surround it. Oceanographer and National Geographic Explorer Kristina Brown is studying this basin, connecting local Inuit wisdom with modern oceanographic research to explain how this resource-rich oasis at the top of the planet exists. Rolex and the National Geographic Society are partnering on science-based expeditions to explore, study, and document change in the planet’s unique regions.
