Full Description
The oceans cover over 70% of our planet. They are host to a biodiversity of tremendous wealth. Its preservation is now a global priority featuring in several international conventions and a confirmed objective of European policies and national strategies. Understanding the dynamics and the uses of the marine biodiversity is a genuine scientific challenge. Fourteen international experts have got together and identified five priority research themes to address the problem, based on analysing the state of knowledge.
