The Dark Sound of the Moon

8/1/2018
More
On August 21, 2017, a total solar eclipse swept across the continental United States from Oregon to South Carolina. Millions of people stood looking up at the sky, their mouths agape, as the Sun’s disk was completely covered by the Moon. For many people, the experience of day turning into night and back into day, and the sight of the Sun’s corona streaming out behind the dark circle of the Moon, is a picture they’ll remember for the rest of their lives. But what about people who are...

From Landfills to Martian Hills

7/2/2018

Building instruments to search for the building blocks of life in the rocks of Mars is no small feat. These gadgets must endure spaceflight, landing on the Martian surface, intense radiation, wild swings in temperature, uneven surfaces and then beam data collected millions of kilometers away back to expectant researchers on Earth. In this episode, NASA geochemist Jennifer Stern gives an insider's view of the ups and downs of testing and deploying one of these instruments - a mass...

The Secret Lives of Tide Gauge Operators

6/1/2018
More
In the 1800s and early 1900s, dozens of men stationed at harbors around the United States would record water levels and send them to a central office in Washington, D.C. where they were used by engineers building the country’s infrastructure. Along with these readings, the tide gauge operators also sent letters detailing their lives at these outposts and the difficulties they faced, from extreme weather to personal dramas. Stefan Talke, an assistant professor of civil and environmental...

Journey to the Center of the Ice

5/1/2018
More
From the outside, glaciers appear to be solid masses of unmoving ice. But meltwater flowing from the surface down to the glacier bed carves canyons, gorges and even caves into the dense sheets of ice. Over time, the fissures form labyrinthine tunnels that open into vast ice caverns few people have ever seen. University of Oregon glaciologist Kiya Riverman is one of a handful of researchers who ventures into this frozen world of glacier ice caves. What started as a hobby exploring...

Alvin and the Ocean Deep

4/2/2018
More
The ocean floor is a deep, dark, cold, scary place filled with terrifying creatures and scorching fissures where boiling magma emerges from Earth’s crust. So what’s it like to be a scientist whose job it is to study these dangerous things up close and personal? In this episode, Adam Soule of Woods Hole Oceanographic Institution describes his experiences descending to the seafloor in the human-occupied submersible Alvin. Listen to Adam describe the painstaking work of documenting every...

Chasing Narwhals, Unicorns of the Sea

3/1/2018
More
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. In this episode, Kristin talks about what it is like to study these creatures, including the first time she saw a narwhal, what polar bear fur...

Science at a Glacier’s Edge

1/31/2018
More
In southeast Alaska, a team of scientists faced boat-blocking icebergs, calving-induced tidal waves, and cold, dreary days. All in the name of science. Using a hogde-podge of instruments ranging from radar to drone boats named Rosie and Casey, these scientists set out to brave the seas to understand a glacier. In this episode, listen to oceanographer David Sutherland describe his experiences at Le Conte glacier, the southernmost tidewater glacier in the northern hemisphere. Sutherland...

Parking Lot Lava

12/1/2017
More
In a parking lot behind the Comstock Art Facility at Syracuse University, geologist Jeff Karson and sculptor Bob Wysocki cook up something almost unimaginable – homemade lava. Using a gas furnace the size of a small truck, the two professors melt gravel typically used for roadbeds into hot molten rock that they pour onto sand to recreate natural lava flows seen in places like Hawaii, Iceland and Italy. In this episode, listen to Bob and Jeff describe their eight-year lava-making journey,...
