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.
