E6 – Bonus Clip: Newspaper is the New Duct Tape

Check out this clip that didn’t make it into our recent episode, The Secret Lives of Tide Gauge Operators, with Stefan Talke about some correspondence he found on how operators treated their equipment.             Transcript Shane Hanlon:  Hey, Nanci. Nanci Bompey: Hi, Shane. Shane Hanlon:  Alright, I wanted to ask…

E6 – The Secret Lives of Tide Gauge Operators

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.

E5 – Bonus Clip: Wildlife of Svalbard

Check out this clip that didn't make it into our recent episode, Journey to the Center of the Ice, with glaciologist Kiya Riverman, about her close encounters with animals of the far north.

E5 – Journey to the Center of the Ice

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.

E4 – Alvin and the Ocean Deep

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?

E3 – Chasing Narwhals, Unicorns of the Sea

University of Washington biologist Kristin Laidre travels to the Arctic to study animals many of us have only seen in pictures.

E2 – Science at a Glacier’s Edge

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…

E1 – Parking Lot Lava

Artist Bob Wysocki pours homemade lava onto sand in Syracuse, New York.

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.
