Research published in Global and Planetary Change examines the trends and projected frequency, intensity and duration of marine heatwaves (MHWs). A MHW is a 'discrete, prolonged anomalously warm water event' lasting five or more days, with temperatures warmer than the 90th percentile relative to climatological values. The research focuses on Fiji, Samoa and Palau in the tropical western and central Pacific Ocean region (TWCPO).
