自1951年以来，加州南部附近沃茨的大型浮游动物生物量减少了80%。在同一时期，表层变暖-在某些地方超过1.5摄氏度-温跃层的温差增加。增加分层导致较少的升降温跃层由风驱动的上升流。较浅的涌上沃茨源为新的生物生产提供的无机营养物较少，因此支持的浮游动物数量较少。持续变暖可能导致浮游动物数量进一步减少。
Since 1951, the biomass of macrozooplankton in waters off southern California has decreased by 80 percent. During the same period, the surface layer warmed-by more than 1.5 degrees C in some places-and the temperature difference across the thermocline increased. Increased stratification resulted in less lifting of the thermocline by wind-driven upwelling. A shallower source of upwelled waters provided less inorganic nutrient for new biological production and hence supported a smaller zooplankton population. Continued warming could lead to further decline of zooplankton.
