Description
The modern study of the ocean floor began in 1936 when Charles Snowden Piggott (1892-1973), a chemist on the staff of the Geophysical Laboratory of the Carnegie Institution of Washington, announced that he had invented a “hollow punch” which is thrust into the ocean by an explosion of powder and, when hauled back, brings up a rock core of the ocean bed. The Geophysical Laboratory donated this piece of a Piggott core sampler to the Smithsonian in 1950.
