Our knowledge of the ocean has increased tremendously with the advent of new technologies. How deep-sea animals can exist in places where no food is produced has long been a mystery. The seafloor in the abyss off the coast of California was studied for 24 years, and these investigations are contributing to our understanding about how conditions at the surface of the ocean control deep-living biological communities.
