Marine Heatwave Linked to Dead Seabirds Along California Coast
A significant increase in dead and emaciated seabirds has been observed along California's coastline, with experts attributing the phenomenon to a marine heatwave. According to the Los Angeles Times, ocean temperatures have risen 4 to 8 degrees above average in some areas, disrupting the marine food web. Species such as Brandt’s cormorants, loons, common murres, and grebes are among the most affected. Warmer waters are driving fish and other prey to deeper or cooler areas, making them less accessible to seabirds. Additionally, nutrient circulation in the ocean has been stifled, further impacting the food chain. Reports indicate that juvenile birds, particularly those born after a robust breeding season, are struggling to survive due to starvation and weakened immune systems. The marine heatwave spans from San Francisco to the Mexican border, with record-breaking temperatures recorded at locations like La Jolla's Scripps Pier.
