The coastal locations of the SWFSC laboratories enable scientist to access many species from shore-based stations nearby.  Studies from these stations provide long-term data on the abundance, distribution, and biological characteristics of fish and protected species populations.  Examples include over a decade of monitoring the northbound migration of gray whale cows and calves from Piedras Blancas, a point of land just north of San Simeon, California, and long-term monitoring of the green sea turtle population in San Diego Bay.  In Antarctica, two shore-based stations are occupied in the austral summer months.
