The 1950's have comprised an exciting decade in the science of the sea. During this period a manned vehicle has descended to the deepest hole in the ocean floor. During the 'fifties, also, the crossing of the entire Arctic basin was accomplished by submarines traveling under the ice. Many new features of the unseen floor of the sea have been described, including new mountain ranges that now appear to be linked with others to form the longest and mightiest mountains of the earth-a continuous chain encircling the globe. Deep, hidden rivers in the sea, subsurface currents with the volume of a thousand Mississippis, have been found. During the International Geophysical Year, 60 ships from 40 nations, as well as hundreds of stations on islands and seacoasts, co-operated in an enormously fruitful study of the sea.

In our own lifetime we are witnessing a startling alteration of climate.
Day by day and season by season, the ocean dominates the world's climate.
F or the globe as a whole, the ocean is the great regulator, the great stabilizer of temperatures. It has been described as 'a savings bank for solar energy, receiving deposits in seasons of excessive insolation and paying them back in seasons of want. Without the ocean, our world would be visited by unthinkably harsh extremes of temperature.
