What draws people to the poles again and again? What significance do these regions hold for the planet? Begin to answer these questions with Fen Montaigne, a journalist who has traveled extensively in the polar regions, as you delve into the awe-inspiring story of Ernest Shackleton's struggles in Antarctica, as well as Montaigne's own experiences.

Humans are extracting krill and other marine life at unprecedented levels. Burning fossil fuels is causing ocean acidification. What will happen if we change the temperature or chemistry of the ocean? Consider such questions in this lecture on the delicate ecosystems of Earth's oceans and the consequences of treating oceanic wildlife as commodities.

Legendary Antarctic adventurer Apsley Cherry-Garrard said "all the world loves a penguin" and in this lecture, you'll understand why. Get acquainted with Adélie, emperor, and chinstrap penguins by exploring how each evolved into the fat, flightless swimmer it is today. Explore the history of their interaction with humans and their remarkable cycles of reproduction and survival.

Meet some of the towering figures of Antarctica's "heroic era," explorers and scientists in the early 20th century who vastly expanded our knowledge of the southernmost continent. Learn what drove these adventurers despite extreme hardship, and witness the treacherous race to the South Pole between Norwegian Roald Amundsen and Brit Robert Falcon Scott.

Virtually every living thing in polar waters - from single-celled phytoplankton to whales - has evolved in a world dominated by sea ice. Study how Arctic and Antarctic marine ecosystems work, and consider what happens to a sea ice-dependent marine ecosystem when the sea ice begins to disappear.

The North and South Poles share a history that is unique and unlike any other place on Earth. Join Professor Michael Wysession as he lays the groundwork for understanding the polar regions with a discussion of their geology - dominated by ice, ocean, climate, and even nearby outer space - as well as their similarities and differences.

Above Antarctica is a cap of stars and constellations hidden from view in the Northern Hemisphere and containing some of the most beautiful sights in the night sky. Survey the region's astronomical highlights and learn why, at the South Pole itself, astronomers and other scientists enjoy research conditions unrivaled anywhere else on Earth.

How do humans get beneath the surface of Arctic ice or the Antarctic Ocean? Join marine conservationist Sylvia Earle, a National Geographic Explorer-in-Residence, as she explains the technologies scientists use to dive safely beneath the sea ice in an effort to expand our knowledge of marine ecosystems at both poles.

Travel to the polar regions with five Arctic and Antarctic experts on an exquisite visual journey, produced in partnership with National Geographic. You’ll encounter incredible wildlife, learn about the “heroic era” of polar exploration, discover how indigenous peoples thrive in these climates, and gain valuable tips on how to take captivating photographs in the otherworldly landscapes.

Delve into the past, present, and future of three of the most notable islands in the Arctic and sub-Arctic: Iceland, one of the world's most geologically active areas; Greenland, which dwarfs all other Arctic islands in size; and the Svalbard archipelago, home to The Global Seed Vault.
