Course Overview

Enchanting and otherworldly in their beauty, the polar regions are some of the most isolated and least understood places on Earth. Until relatively recently, few non-indigenous people had experienced their immense majesty. And yet, while remote, these extreme environments are endlessly fascinating, and eminently worthy of witnessing firsthand, especially if you are prepared to understand what you are seeing.

Now, Polar Explorations, a one-of-a-kind educational journey created in collaboration with National Geographic, provides you a 360-degree view of the Arctic and Antarctica in 22 visually stunning lectures plus bonus video: Unforgettable Moments from National Geographic's Polar Trips. A travelogue, science class, and history lesson rolled into one comprehensive course, Polar Explorations provides you with the context necessary to fully appreciate the splendor of the poles, including insights into:

  • geology,
  • astronomy,
  • zoology,
  • oceanography,
  • history,
  • culture, and
  • photographing unique subjects.

Whether you’ve always dreamed of an expedition to these incredible ice-bound worlds or you’re simply curious about the wonders they hold, this course transports you to some of the most intriguing and alien places on the planet. Through powerful, rare images and extensive video, these lectures offer you a captivating, in-depth look at what makes these places so exceptional and why they beg to be studied. This spectacular footage, shot on location during voyages with National Geographic Expeditions—the travel program of the National Geographic Society—provides you with an immersive experience unmatched by anything short of actually journeying to the ends of the Earth.

Take this opportunity to venture to the polar regions and you’ll witness breathtaking sights unparalleled on our planet, including:

  • Antarctic ice sheets covering an area one-and-a-half times the size of the United States and up to three miles deep (representing 90% of the world’s ice and 70% of its fresh water);
  • magnificent blue icebergs and massive calving glaciers;
  • periods when the sun and the moon are continuously visible and never set;
  • astonishing seabirds, from penguins and puffins to skuas and petrels;
  • bizarre sea-based life-forms such as diatoms and sea butterflies; and
  • other remarkable wildlife in action, including polar bears, Arctic foxes, walruses, narwhals, seals, and orcas (also known as killer whales).

An Educational Adventure Led by Five Noted Authorities

Not only does this unforgettable educational journey feature spectacular National Geographic footage but also it presents a multidisciplinary team of renowned instructors hand-picked by National Geographic and The Great Courses, who share their expert insights on these ever-changing places.

You’ll begin with Pulitzer-Prize nominated journalist and National Geographic magazine contributing writer Fen Montaigne on the question of why people journey to the poles—from intrepid 19th-century explorers like Ernest Shackleton to today’s leading scientists—and discover an answer more complicated than you might imagine.

Directing your attention skyward to explore the regions’ unique relationship with the heavens is Edward Murphy, Associate Professor of Astronomy at the University of Virginia. Adopting an astronomer’s-eye view of the poles, you’ll investigate:

  • why the sun behaves differently at the North Pole, rising and setting only once each year;
  • how Antarctica has changed throughout history, with evidence showing it was once a jungle-covered landscape;
  • why Antarctica is the world’s best place to conduct certain kinds of astronomical research;
  • what causes seasons and how they’re experienced at the poles; and
  • spectacular auroras and other unique polar phenomena.

Next, Michael Wysession, Associate Professor of Earth and Planetary Sciences at Washington University in St. Louis, reveals the fascinating geology and geography of the poles, from how they were formed to how they continue to evolve. You’ll come to understand the differences between the Arctic and Antarctic environments—the former a vast frozen ocean surrounded by diverse landscapes, the latter an icy desert continent—as well as their many similarities. Professor Wysession also illuminates how conditions in each location drive the global conveyor belt of ocean currents and winds that heat and cool the earth.

Surviving in a Frigid World

In addition to the marvelous footage of ice, snow, and ocean you’ll witness in these lectures, Polar Explorations shines a spotlight on the many amazing forms of life that call the polar regions home. Some of the wildlife you encounter will be familiar, such as the polar bears of the Arctic and Antarctica’s many penguin species. Others may be somewhat foreign, from the microscopic creatures that live beneath the surface of the sea ice to the amazing Arctic tern—a bird that makes pole-to-pole migrations of 40,000 miles a year or more. You’ll also take a deep dive into marine ecosystems with National Geographic Explorer-in-Residence and marine conservationist Sylvia Earle, who explains the central importance of sea ice to virtually every living thing in polar waters—from the tiniest phytoplankton to the largest whales.

You’ll come to understand the interdependence these creatures have with each other—and with the ice—in these delicate ecosystems, as well as the history of human-wildlife interactions. Particularly eye-opening are lectures on the native peoples of the Arctic, including the Inuit of North America and Sami of Eurasia, who have made their home in Alaska, Canada, Greenland, Russia, and the Nordic countries for millennia. Equally thought-provoking are the findings in zoology, oceanography, physics, and climatology emerging from research stations at both poles. This research, as you’ll discover through riveting stories of triumph and tragedy, wouldn’t be possible without the efforts of American and European explorers of the 19th and 20th centuries who risked their lives to map the unknown reaches of both poles, opening these frontiers to science.

A Photographer’s Dream Come to Life

For those who plan to visit the polar regions, learning how to take compelling photographs in these unusual environments will aid in capturing memories of the abundant wildlife and stunning panoramas. For this reason, the course concludes with a pair of lessons on polar photography presented by Ralph Lee Hopkins, the founder and director of the onboard photography program for the National Geographic-Lindblad Expeditions fleet. These lectures provide special insight into the unique opportunities and unexpected trials of photography at the ends of the earth.

Hopkins, who has two decades of Antarctic and Arctic experience, addresses not only the basics of preparation and gear, but also offers advice on overcoming the creative challenges of shooting at the poles, such as white-on-white vistas and animals in action. With these expert tips and tricks added to your repertoire, you’ll find yourself better prepared to take stunning photographs that capture the true majesty of these frozen worlds.

Journey to Awe-Inspiring Environments

Our unique partnership with National Geographic affords us the rare opportunity to bring lifelong learners and prospective travelers a truly cross-disciplinary lecture series that taps into the life experiences and expertise of top professionals and professors in their fields. The course is lavishly illustrated with rare and unique footage from National Geographic trips and scientific explorations, custom-made animations, and historical photos and film. Maps, charts, diagrams, and studio demonstrations are also employed throughout these lessons to enhance your comprehension.

Polar Explorations is a veritable feast for the eyes, but this comprehensive course does so much more than showcase the beauty of these remarkable locales. It gives you the scientific and cultural context necessary to understand their unique nature and irreplaceable value—not only to the people and wildlife that inhabit them, but to all humanity.

National Geographic Polar Explorations is rated 4.1 out of 5 by 29.
Rated 3 out of 5 by from Could have been much better This course isn’t bad but it isn’t good. It seems to be a course looking for a subject. It could have been so much more. First it is mislabeled. Most of the course isn’t about Polar exploration. A better title would have been Polar regions explored. The ecological, geographical, geological and oceanographic lectures were fine if not great. The Dr. Earle lectures were great but not extensive enough. Maybe I’m a tech geek but I would have liked far more coverage of how the deep diving equipment worked. In fact a few more lectures on Prof. Earle’s explorations and equipment would have been welcome. The astronomical lectures were interesting but a bit far afield. The photographic lectures were so far afield that they were almost on another planet, and not in a complimentary way. If I wanted a course on photography The Great Courses has several. What good are lectures on arctic photography when I don’t know what an ISO is? A better lecture on climate change could have been given by Dr. Wolfson or Dr. Hazen both in the Great Courses’ collection of excellent lecturers. Any course by either of these Professors is well worth the viewer’s time and money. I was also bothered by the lecturer’s light dismissal of the slaughter of tens of thousands of reindeer rabbits and cats ( I can live with the rat extermination) to return areas into their pre human contact condition. What makes an arctic bird worth more than a rabbit or reindeer or cat?? Likewise there is the moral conflict of condemning (implicitly) the Japanese for still whaling while approving Inuit hunting. Neither group has to eat Whale in the modern world and once upon a time all of mankind was completely dependent on slaughtering and eating our fellow creatures. I am going to listen to the good parts of this course again, selectively, but I can’t recommend the course in its present form.

Rated 4 out of 5 by from A Great Opportunity Comes Up Short I ordered this course shortly after my wife and I had returned from an expedition cruise to the Antarctic Peninsula. The trip closed the circle on our seventh continent and was genuinely spectacular. It is for this reason that I had extremely high hopes that this series of lectures would not only be highly evocative but equally spectacular in its own way. It was an unrealistic and unfair expectation. Still, I have given it four stars for its effort at scientific authenticity and for the attempts by the course's presenters to convey their commitment to open these polar regions to us and, more importantly, to preserve them. The presenters are surely well-schooled in their crafts but, with a few exceptions, are not comfortable communicators. I choose not to specify which I found least capable, but they were so tethered to their teleprompters that, without them, they would have slipped beneath the polar ice. Production values, in particular the faux realistic "polar" sets, were simply a distraction. I found that most potentially great teaching moments went begging. If you never have the opportunity actually to visit these areas, the course will open your eyes. Once you've been there, particularly in the company of a good ship and professional botanists, ornithologists and geologists, I fear you'll find that the course cannot really deliver. I recommend it for its earnest attempt to educate.

Rated 5 out of 5 by from Title was fine. Very interesting course. Photography was excellent. I liked the variety of speakers. The lady professor had a very good sense of humour. I would like to have seen an episode on Admiral Byrd, his flights and survival alone during the Antarctic night. Also, the comercial exploitation of krill for omega-3 pills and future towing of icebergs for freshwater.

Rated 4 out of 5 by from Pretty good. Not as academically-oriented as other Great Courses selections, but perhaps the intent of the National Geographic partnership is to have presentation and production values geared to a wider audience. Just something to keep in mind. Overall, I enjoyed the lectures, which were lavishly illustrated. It was a little distracting different people do the lectures, but not excessively so. The focus is wide, going from wildlife, to geology, to astronomy, to photography, to history. So that is another thing to keep in mind - this is not a focused, subject matter course. And not highly academic either. But, enjoyable for what it purports to be.

Rated 5 out of 5 by from National Geographic poplar Exploration As a photographer I’m always looking for new locations to visit. I purchased this dvd with that in mind. After viewing this dvd I have added this area to my wish list.

Rated 2 out of 5 by from Disappointing I became enthralled with the Polar Regions while visiting the Arctic and Antarctica on cruises, and I hungered to learn more about them. So, I was delighted to find this course. Since it had been produced in collaboration with National Geographic, I imagined it would include stunning photography and video. And because it has five presenters, I expected topics would be covered by individuals with unique expertise. I didn’t bother to pay attention to the reviews. That was a mistake. Instead of savoring this lecture series, I forced myself to sit through it because I’d paid good money and didn’t want to accept I’d wasted it. I did needlework while watching so my time wouldn’t be wasted, too. I learned little or nothing from the majority of lectures. However, a few were excellent. I would not call this a course: it’s a set of disjointed lectures by five different people. It lacks coordination, jumping from topic to topic. There is overlap and repetition of subject matter among presenters with some content covered as many as four times. Various lectures use the same (apparently stock) photos and video clips, which occasionally don’t really illustrate what the presenter is talking about. In these cases they are more distracting than helpful. Most disappointing to me is the lack of depth in most lectures. Only two presenters are college professors. More than half of the lectures, 12 of 22, are delivered by a journalist. Mr. Montaigne’s tales of the exploits of early explorers and his own experience encountering penguins in the Antarctic are interesting. If you like a good storyteller, you’ll probably enjoy his anecdotes. However, his lectures on indigenous people of the Arctic, sea ice, marine and terrestrial animals, and seabirds are disappointingly superficial. I learned almost nothing from them beyond what I had already learned during my own brief visits to the Arctic and Antarctica. This lecture series could have been far better if the history and culture of indigenous people and the flora and fauna of the Polar Regions had been covered by people with a greater depth of knowledge and true expertise on these topics. In a “great course,” scientific topics need to be covered by scientists, not journalists. The three lectures by Dr. Michael Wysession, a professor of Earth and Planetary Sciences are excellent – substantial, interesting, well-organized, and well-presented. He discusses and explains geologic features and climates of the Polar Regions, circulation of ocean currents, the earth’s magnetic fields, and the auroras. The two lectures by Ralph Lee Hopkins, National Geographic photographer, are also excellent. While he focuses on the unique challenges of taking pictures near the poles, his tips will help you improve your photography wherever you are shooting. The three lectures by professor of Astronomy, Dr. Edwin Murphy, are a mixed bag. He is knowledgeable and presents well, but much of what he covers in “Seasons at the Poles” is so basic I learned it in elementary school. Other material, however, was new and interesting: the idiosyncratic movement of the sun through the sky and pattern of visibility and invisibility of the moon at the poles; stories the Inuit told about constellations; and specific ways the Inuit used movement of stars for timekeeping, navigation, and tracking the seasons. In his third lecture, though, it seems Dr. Murphy has run out of relevant material. He goes off on long tangents to galaxies far, far away and discussions of neutrinos – the only relation to the Polar Regions being research conducted in Antarctica. The two lectures by National Geographic Explorer-in-Residence and Marine Conservationist, Dr. Sylvia Earle, are a total waste. The content is boring and has little to with little to do with the Polar Regions; and the delivery is difficult – almost painful – to listen to, due to Dr. Earle’s slow, halting speech. I thought a lecture titled “Diving Under Polar Ice” would show me what it is like under the ice, what one would see and experience there. Wrong. It is all about equipment and technology needed to explore icy waters and ocean depths, and how much Dr. Earle loves being underwater. There’s only one brief glimpse of a diver actually in icy water. Her other lecture can best be described as a rambling lament about humans using marine animals as commodities, concluded with an uninspiring suggestion for conservation: humans need to think about what we are going to do before we do it and see value in creatures beyond that as commodities. One other thing to note: This series would have been remiss if it had not included discussion of climate change and its effects on the Polar Regions. However, it does not need to be in nearly every lecture. Mr. Montaigne, it seems, feels a need to mention it repeatedly throughout his lectures in case listeners have forgotten in the last five minutes that polar ice is melting and we need to be concerned. Thankfully, other presenters discuss the topic without harping. If you know little or nothing about the Polar Regions and are looking for a light, introductory overview you will probably find several of the lectures in this series to be enlightening. But if you are looking for something with more substance, up to the typical standards of Great Courses, you will likely be deeply disappointed and frustrated as I was.

Rated 5 out of 5 by from Clarifies this complicated history of discovery. A history of Polar exploration well explained. I Visited Scott's hut near McMurdo Station in 1965 on board USS Glacier (see photo) - The Course gave me a great refresher of my two trips "to the ice" and filled in the blanks of what I did not fully appreciate or understand at the time.
