#InMemoriam - The Marine Institute was saddened to hear of the untimely passing of esteemed colleague and friend Dr Kostas Nittis of the Hellenic Centre for Marine Research in Athens.

A distinguished oceanographer, Dr Nittis served the marine science community as secretary general of the European Global Ocean Observing System (EuroGOOS) and as chair of the European Marine Board.

But his sphere of influence extended well beyond his own research field. Through participation in multiple pan-European projects and networks, Dr Nittis was described by the Marine Institute as "a true ocean champion and ambassador, ceaselessly promoting of marine science and setting the European marine research agenda.

"Those fortunate to have known and worked with Kostas will remember his wisdom, integrity, diplomacy and a steady calmness which concealed a determination to effect positive change."
