‘Return to the Sea’ is a citizen science initiative which seeks to collect the maximum number of observations of marine biodiversity on the coastline in July, August and September. Although it is focused on the Catalan coastline, everyone is invited to participate. 

The campaign is encouraging citizens to (re)connect with nature after all these months at home, to discover a wide variety of marine species and to share it with others.
