When we look at the sea today we find a new world being unfolded. We find oceanology, the art of living on and using the sea-bed, no longer the sole domain of Jules Verne. Whole areas are devoted to the production of oil and gas from the seabed, with their rigs bringing literally new horizons as well as new hazards. Whole areas of the sea required for mankind's subsistence will be set aside in the eyes of civilization for purposes other than navigation. The sea will no longer be sacrosanct to ships and seamen alone.
