The waters of the Great Bear Rainforest are filled with beautiful species and plenty of mysteries. Where marine mammals travel, and where they make the most noise, is largely based on anecdotal evidence.
But a new project hopes to improve our data with underwater microphones, known as hydrophones.
The environmental group Pacific Wild has placed six hydrophones in the waters just off the Central Coast. Working with the Heiltsuk Nation, they’re hoping to get a better sense of how animals use the waterways by monitoring ocean noise over time. You can listen to some of the hydrophones and see exactly where they’re located here.
