With a reputation as cold, forbidding, and remote, Antarctica can also be a fragile place, home to an incredible variety of life along its edges. Join National Geographic explorer Jon Bowermaster as he and his team travel along the continent’s frozen coastline in Antarctica 3D: On The Edge. The adventurers explore by sea kayak, ice-worthy sailboat, and on foot to gain an up-close look and attempt to better understand just how the seventh continent is changing—and in some parts changing very fast—in part due to a warming ocean. Meet scientists and the wildlife they study up-close and learn about the history of exploration and the continent’s future. From its place anchoring the bottom of the globe, Antarctica might seem too frozen to have any impact on the rest of the planet. But the very fact that it is constantly changing—the sea around it freezing and thawing every year—makes it the planet’s beating heart, its rhythm intimately influencing the earth’s weather, ocean currents and climate.
