CENTENARY OF THE SPEECH ON THE OCEAN FROM PRINCE ALBERT I  

One hundred years ago, on 25 April 1921, Prince Albert I gave his Speech on the Ocean at the Smithsonian Museum, in front of the members of the Washington Academy of Sciences. It was a visionary speech, predicting some of the problems that affect the oceans today, such as the overexploitation of resources caused by new technology – at the time represented by steam trawlers. During this trip, Prince Albert I was awarded the Agassiz Medal in honour of his significant contribution to oceanography.
