El Niño Forecast Raises Concerns for California Sea Lion Pups Amid Potential Mass Strandings
California is bracing for a powerful El Niño this winter, which, combined with an ongoing marine heat wave, could lead to a significant increase in starving sea lion pups washing ashore. The Marine Mammal Care Center in San Pedro, which typically rescues hundreds of marine mammals annually, fears a repeat of the 2013-2016 period. During that time, an El Niño event and an ocean heat wave known as 'the Blob' resulted in thousands of malnourished California sea lion pups stranding on beaches. The primary concern is the impact on upwelling, a natural process where cold, nutrient-rich water rises to the surface, providing abundant food for marine life. El Niño and marine heat waves can disrupt this process, reducing food availability, especially for young animals.
