South Western Milos island

Southern Cyclades, Aegean sea. A volcanic island, famous for its obsidian since the antiquities, its prehistoric settlements and its pirate history during the 16th and 17th century AD. The still active geological processes have crafted a unique coastal environment whose extension beneath the sea surface holds many surprises...   

The rocky coasts of Milos island still hold their dense algal forests, the seagrasses grow in high density and extent, while the sand at some specific spots here is teeming with... hydrothermal activity! CO2 and methane bubbles escape the bottom, the temperature of the sand reaches 100 degrees Celsius, while a community of bacteria spreads along the seafloor for hundreds of square metres, until waves raised by the southern winds start shifting the sand, and in effect destroying their white delicate mats.
