Soundscape ecology is a growing field of research that uses sound to track how ecosystems change over time. Bryan Pijanowski and Matt Harris work with a team of researchers to collect hours of sound at locations from the Alaskan tundra to a rainforest in Borneo. By analyzing the recordings they can reveal changes in each ecosystem that we might not otherwise be able to see.

Six miles off the coast of Key Largo and 63 feet below the ocean surface sits the world's only undersea marine laboratory, the FIU Aquarius Reef Base. There, researchers from Florida International University, Northeastern University, and MIT recently joined documentarian Fabien Cousteau for Mission 31. The month-long project aimed to study the effects of global warming and ocean acidification on nearby Conch Reef and raise awareness of fragile ocean ecosystems. Follow Liz Bentley Magee, a mission scientist, as she lives, works and sleeps under the sea.

As you may have noticed while tracking a hurricane on the news, storms in the Northern Hemisphere spin counterclockwise, while those in the Southern Hemisphere spin clockwise. Why do storms spin in different directions depending on their location? And why do they spin in the first place? The answer is a phenomenon called the Coriolis effect.

Coney Island has a long history of beach nourishment—the process of adding sand to a coastal area to repair an eroded beach. It was the site of the first beach nourishment project ever in the 1920s, and in the months since Hurricane Sandy, a new beach nourishment project has begun. But will it still make sense to repair the beach in another few decades?
