ClimateOcean temperatures
Quick Answer
A marine heatwave is a period of unusually warm ocean temperatures lasting days to months. It can cause mass die-offs, coral bleaching, and shifts in marine species.
The Full Story
Marine heatwaves occur when ocean temperatures are much higher than the local seasonal average for an extended time. They can be driven by atmospheric patterns, weak mixing, or long-term warming trends amplified by climate change. One well-known example affected the northeast Pacific from 2013 to 2016 and was nicknamed “the Blob.” These events can disrupt fisheries, coral reefs, kelp forests, and the distribution of marine animals.
