Exploring Monterey Bay National Marine Sanctuary

Experience one of nature's most incredible light shows when just beneath the kelp-forest canopy. With the help of gas-filled floats, giant kelp reaches towards the sunlight at the water's surface. Under optimum temperature, sunlight, and nutrient conditions, giant kelp can grow as much as two feet in one day and can reach maximum heights of 200 feet. (Photo: Pete Naylor/REEF)
