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.  

Tamandaré has been in the center of the extreme heatwave, and the water has finally started to cool down. From February to May, the temperature has been above the bleaching threshold for corals. Around 4 months of being above the bleaching threshold proved to be mortal for many of the corals. This site is managed by PELD-TAMS. 

Here are three surveys conducted at the Tamandaré site, all taken at the same location and position. The first survey, conducted on February 22nd at the beginning of the heatwave, shows healthy coral. The second survey, conducted on March 26th in the middle of the heatwave, shows bleached corals. The final survey, conducted on May 25th, right after the heatwave, shows dead corals.

The small circles in the graph indicate that a survey was conducted at that date. Explore more in the Tamandaré Aqualink dashboard below.  Surveys were conducted by Ágatha Naiara Ninow and Thales Vidal with PELD TAMS. 

The island of Fernando de Noronha Archipelago is in the heart of the extreme heatwave in Brazil. Around 100% of the corals are bleached down to 27 meters. Below are a few videos that display the current condition of the reefs around the island. This site is managed by PELD ILOC.
