A study conducted by Professor Terry Hughes on 1036 reefs in March 2020 brings sad news. Indeed, massive bleaching is once again hitting Australia’s Great…
Symbiosis and coral bleaching description A symbiosis (a beneficial association between two organisms) often exists between corals and dinoflagellate microalgae (symbionts). This symbiosis is known…
Symbiosis is a fascinating biological principle, showing the interdependence of living beings between them. In the face of climate change, these relationships are being altered…
Coral bleaching The sea surface temperature has increased by 0.1 ° C per decade over the last century (Levitus et al., 2005, IPCC 2013). The…
Rising ocean temperatures Oceans take up 71% of the surface of the Earth. They are essential to climate regulation because of their exchange with the…

During the last global bleaching event (2014-2017), portrayed as the most spectacular in terms of intensity, duration and extent, the Great Barrier Reef lost more…
The oceanic heat waves are getting closer and closer together. Over the last two decades, we have had four! Unfortunately, 2016 and 2017 were brutal…
Already weakened by local damages (overfishing, pollution, coastal development) and global damages (rising surface water temperatures and acidification of the marine environment), coral reefs face…
Coral reefs are living underwater mosaics that offer us an unparalleled spectacle every dive. Often compared to tropical rainforests due to their exceptional diversity, these…
