The California gray whale commutes along the Pacific west coast every year, either on its way to feeding grounds near Alaska or to calving waters on the Mexican coast. The SWFSC has been monitoring their recovery at field stations in Piedras Blancas and Granite Canyon. Over the past 10 years, the growth of this population appears to have stalled and calf production has been highly variable. In addition, some scientists have noted the presence of whales in the lagoons that appear unusually skinny. The accompanying interview with SWFSC researcher Wayne Perryman covers these observations and how they may be linked to the impacts of global warming on the primary feeding grounds for Eastern Pacific gray whales in the Arctic.
