How People Saved the Seabirds of the California Current.
The San Francisco Bay Area is bordered on the west by the California Current, one of five upwelling-driven “boundary currents” on Earth where the vast majority of the world’s fishery harvests occur. These boundaries are the edges of major oceanic gyres, like the North Pacific Gyre in the case of the California Current. The incomparable productivity of these stretches of ocean are generated by strong, persistent winds that bring the upwelling of nutrient-rich water from the depths into the sunlight where phytoplankton, the base of the food web, can thrive.
