Heatwave in Brazil 2024 - Almost 100% of corals are bleached

Track the Brazilian heatwave on Aqualink: https://highlights.aqualink.org/brazil-heatwave-tracking-live

A large part of the Brazilian coastline is currently experiencing an extreme heatwave, which has as bleached up to 100% of the corals in some reefs. The heatwave has brought consistent temperatures above the bleaching threshold since February 2024, which is a very long time for corals. Temperature increases above the bleaching threshold for corals can result in bleaching, which will eventually kill the coral completely.

The interactive map shows all the sites monitored in this region using Aqualink. The colors in the ocean display the accumulated heat stress that the ocean is experiencing in that location. The longer the water has been higher than the bleaching threshold, the more heat stress the site is experiencing. This is measured by Degree Heating Weeks (DHW). Each dashboard receives temperature data from NOAA satellites. The two sites with a hexagon shape have additional temperature data gathered by Sofar Smart Mooring buoys.
