Next, Skype takes Oprah from one end of the earth to the other! Neal, a scientific researcher stationed in Palmer Station, Antarctica, logs on to share a glimpse of the Antarctic Ocean and its glaciers.

At Palmer Station, which is located just 2,000 miles north of the South Pole, Neal says he and 29 other scientists research everything from the upper atmosphere to the bottom of the ocean. When they're not working, he says there are a lot of ways to pass the time.

"We see whales, penguins, seals, all sorts of marine wildlife here," Neal says. "We can go boating. We can climb the glacier, and really, it's all about the community down here. We can just converse with each other and that's how we entertain ourselves the most."
