At the beginning of April 2012, several people alerted us to the presence of bleached plant life in the cove of Corton in the village of Cassis.

To understand this phenomenon, Surfrider immediately contacted its expert network, and in particular a marine biologist.

We discovered that they were Coralline algae, whose fronds are covered with calcareous deposits and which had bleached in the sun due to the anticyclonic conditions of the previous days. This had led to barometric tides and a much lower water level than usual.
