As part of the Defending Our Oceans Tour, Greenpeace Italy placed a temperature monitoring station at Elba island, in the area of the Pelagos Sanctuary, and worked in partnership with the University of Genova to study the impact of climate change on underwater coastal biodiversity. First project results' indicate raising temperature are killing iconic underwater organisms as protected pen shell Pinna nobilis and colonies of the sea-fan gorgonia (Paramuricea clavata) and favouring unusual mucilage events that cover completely the substrate, suffocating organisms.
