Explore the stark landscape, frigid sea, and wild animals in one of the most remote and inhospitable places on Earth. National Geographic Pristine Seas Explorer-in-residence Enric Sala leads a group of scientists on the first international scientific expedition to Franz Josef Land. His team works with Russia's most formidable biologists, geomorphologists and ornithologists to understand how climate change is affecting this remote ecosystem. From diving in subzero temperatures to running away from polar bears to avoiding titanic icebergs, the Pristine Seas team faces some of its most dangerous challenges to date.
