Marine heatwave forecasts – August 3rd, 2024 – Reposted from Mercator Ocean International

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 Tropical Atlantic Ocean – In the Tropical… Read More
