About Narwhals

With their long tusks, narwhals are unique whales that live in the Arctic Ocean.

Impact of Climate Change

But as climate change causes global temperatures to rise, less and less sea ice is covering the Arctic Ocean each year. Narwhals are left vulnerable without the ice, which historically provided them with safe areas to roam out of reach of their natural predators, killer whales.

Human Activities and Challenges

And humans are taking advantage of the clearer water, searching and drilling for oil and hauling cargo. So as Arctic sea ice shrinks, a new challenge emerges: noise pollution from human activity.

The thrum of engines and other man-made sounds threaten narwhals' ability to locate food, communicate with other narwhals, and use echolocation to navigate while migrating.

Protecting Narwhals

How can people reduce noise pollution in the Arctic Ocean to help them? Follow along as scientists study the effects of noise pollution on narwhals and work to ensure they have a hope-filled future.
