Staff Picks: Chasing Narwhals

University of Washington biologist Kristin Laidre travels to the Arctic to study animals many of us have only seen in pictures. She has successfully tracked down the elusive narwhal and been up close and personal with a polar bear seeking to understand how the loss of sea ice and the effects of climate change are altering Arctic ecosystems.

E25 – Antarctica’s Oldest Ice

Drilling engineer and ice core scientist Robert Mulvaney has driven thousands of kilometers over Antarctica in the past few years in a snow tractor, creeping slowly over one of the highest points of the ice sheet, near a location known as Dome C. He’s looking for the perfect place to drill one and a half million years into the past.

Special Release: Deviations from the Norm

One of the most alluring parts of Earth and space science is that much of the key research takes place in the field, in some of the most incredible – and inhospitable – environments on the planet: on treacherous polar ice sheets, aboard sea tossed ships, at the mouths of active volcanoes, beneath turbid ocean…

Centennial E6 – A Tale of Two Journeys

In 1911, two competing groups of explorers attempted to be the first to reach the South Pole. In this episode, atmospheric scientist Ryan Fogt recounts the journeys of Robert Falcon Scott and Roald Amundsen and discusses how extraordinary weather that year affected the two polar parties in vastly different ways.

E17 – Science Turns to Search and Rescue

The Arctic Ocean is topped with a layer of frozen sea water – sea ice – that grows every winter and shrinks every summer. To study the ice in detail, researchers hop aboard an icebreaker ship that can plow through the sharp, cold ice floes without being damaged.

Centennial E4 – Toxic City Under the Ice

In 1959, the United States built an unusual military base under the surface of the Greenland ice Sheet. Camp Century was a hub for scientific research, but it also doubled as a top-secret site for testing the feasibility of deploying nuclear missiles from the Arctic. When Camp Century was decommissioned in 1967, its infrastructure and waste were abandoned under the assumption they would be forever entombed beneath the colossal sheet of ice.
