Seaweed takes scientists on trip 'through time' in the waters of Monterey Bay

New research led by Monterey Bay Aquarium is helping to unlock the natural history of one of the most studied places on the planet. By tapping into a collection of dried, pressed seaweed—that dates back more than 140 years—researchers with the Aquarium's Ocean Memory Lab can now offer a window back in time to understand what the bay was like before the impacts of modern human activity.
