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…
Read MoreE20 – Ballooning on Venus
Venus, Earth’s nearest planetary neighbor, is a rocky world close in size to our own. In our solar system, it is the planet most like Earth. But Earth and Venus have taken different developmental paths, creating curious contrasts for scientists interested in planetary evolution.
Read MoreE19 – Eavesdropping on the Ocean
To those of us on land, the world underneath the oceans seems quiet and serene. But scientists who study ocean acoustics will tell you it is anything but tranquil underwater. Our oceans are home to a cacophony of sounds – from the songs of marine mammals to the cracking of icebergs to the rumbling of earthquakes to the roar of ships.
Read MoreCentennial 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.

Check out this clip that didn’t make it into our recent episode, Science Turns to Search and Rescue, about some of the wildlife that’s found in the Arctic.
Read MoreE17 – 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.

In this centennial episode, she reveals the secrets of the mud, how humans may have weathered climate swings of the past, and what the past can tell us about our warming world.
Read MoreE16 – Gunslingers of the Sea
Snapping shrimp are small but mighty creatures: they’re only a few inches long but are among the noisiest animals in the ocean. The loud cracking noise they make when snapping their claws sounds almost like a gunshot, and when enough shrimp snap at once, the din can be louder than the roar of a passenger jet flying overhead.
Read MoreSpecial Release: Hawaii’s Volcanoes, Water, and…Vog?
Hawaii is frequently described as a paradise in the Pacific Ocean, but for some scientists conducting field work, there can be some challenges to overcome. In this special episode, Kate Brauman, the lead scientist at the Global Water Initiative at the University of Minnesota, describes her field work experiences in Kona on the big island…
Read MoreCentennial 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.
