Meeting people , doing science

Marine science can not wait any longer to deliver benefits to the  entire world (…). I will not miss to use my energy (…) for developing a science that may serve, more than other, as a staff of moral force for the Humanity. Since the surface of the ocean is a link  for all people.”

H.S.H. Albert I, Prince of Monaco
Opening speech at the day of CIESM constitution (Madrid, November 1919)

[more about the CIESM]

CIESM is governed through a structured framework led by a Board, which includes the National Delegates of 23 Member States and is chaired by the President of CIESM. The organization also features an Advisory Board advising on strategic directions, a Director General responsible for overall operations and scientific coordination, and a Science Council composed of chairs from six scientific committees. These groups work together to steer the Commission’s efforts in monitoring and understanding the Mediterranean Sea’s dynamic environment.
