Maine: Researchers Using Sound Waves to Tell Us What's Swimming in Casco Bay
On land, meteorologists use radar to keep us aware of changing atmospheric conditions using radio waves, but when it comes to the ocean, scientists need a different tool to understand activity where our eyes can't go. Fisheries acoustics uses sound waves to detect who's swimming through Maine's waters.
At its core, fisheries acoustics is essentially a really "fancy fish finder," says Arron Whitman, a senior research scientist at The Gulf of Maine Research Institute. The technology utilizes sound to study...
