Short Wave Eavesdropping On Whales In A Quiet Ocean
Jul 27, 2020
Lauren Sommer, NPR's climate correspondent, sheds light on how the pandemic reduced ship traffic, leading to a quieter ocean. She introduces scientists studying this phenomenon, revealing how it has transformed whale communication, particularly for humpback and killer whales in Glacier Bay. The team discusses the profound effects of decreased noise pollution on whale behavior and social interactions. Insights gained during this quiet period could significantly influence future conservation efforts, offering a glimpse into the fragile world of these majestic marine mammals.

Episode notes
Whales in Glacier Bay
- In Glacier Bay National Park, humpback whales migrate from Hawaii to feed.
- These whales are currently experiencing a quieter ocean due to reduced boat traffic.
Importance of Sound for Whales
- Sound is crucial for whales underwater as it travels much farther than light.
- Whales rely on sound for navigation, finding food, and social interaction.
Whale Response to Noise
- Whales respond to noise pollution by getting louder, repeating calls, moving closer, or calling less.
- Studies show that excessive noise can cause chronic stress in whales, as seen in right whales after 9/11.
