Mercator Ocean International (MOi) oceanographers examine marine heatwaves across the global ocean. They analyse a variety of datasets from observations (satellite sea surface temperature maps) to numerical model analyses (assimilating satellite and in situ observations) and derive marine heatwave forecasts for a 7 day period.[1]

Atlantic Ocean

North Atlantic – MOi forecasts that the surface of the marine heatwave in the mid North Atlantic decreases in extend, but increases in intensity from moderate category to strong and locally severe category.  

North Tropical Atlantic – In the Tropical North Atlantic, the intensity of the marine heatwave decreases to strong and moderate categories. 

South Tropical Atlantic – In the Southern Tropical Atlantic, the few areas still in marine heatwave conditions remain stable with moderate categories.
