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.

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.

But water is not as plentiful, available, and clean in all parts of the world. And with climate change, water is going to become (and is already) a limited resource to some. From Arizona to Katmandu, Chris Scott, Research Professor of Water Resources …

E12 – The Oldest Water on Earth

Thousands of feet below the surface of the Earth is salty water that hasn’t seen the light of day in millions or even billions of years. Miners working deep underground had encountered and wondered about the origin of this water for decades, but it wasn’t until the 1980s that scientists started to investigate where this water was coming from and what it might contain – giving researchers clues into how life survives in the deepest parts of our planet.

E11 – Deep Sea Drilling with Dawn

The ocean floor stores a vast amount of information about Earth and its history. Volcanic rocks that make up most of the seafloor tell scientists about the composition of Earth’s interior, and the sediments lying on top of those rocks document what conditions were like when they were laid down millions of years ago.
