THE COVER

The ship on the cover is the trim Atlantis riding the waves about 200 miles south of Bermuda. The first craft built by the United States as an oceanographic research vessel, she traveled more than 1,200,000 miles across the seven seas for a period of 30 years. She “ran” over 6000 hydrographic stations and was used for innumerable dredging, coring, biological, physical, and acoustical research operations. After she was retired from active service at the Woods Hole Oceanographic Institution in Massachusetts, she was sold to Argentina, where she has resumed her role as an oceanographic research vessel.
