-15f ood production from aquatic resources will rival or exceed the spectacular results that have been obtained from applying these new concepts to agriculture. In short, the Pacific testing areas comprise a laboratory in which the biologists have worked with the secondary but long-range problems incident to the peaceful employment of atomic energy. Conditions there are especially suitable for the study of the disposition and distribution in nature of the radioactive by-products of such employment. Biologists have been participants in this scientific team activity since the inception of the atomic tests at Bikini in 1946. This participation has been of almost revolutionary importance to the biologists, for it has given them unprecedented opportunity to observe the biological cycling of radio- active materials deposited on sea and land from the detonation of atomic weapons. But twelve years of field and laboratory work also have demon- strated that the problems of the biologists are those that have fundamental significance too in the larger matter of proper planning for the future use of atomic energy. Experience in the Pacific has permitted the biologists to develop new techniques of investigation and has suggested other areas in which the techniques may be tested and applied. The program in the Pacific, permitting the biologists to use the facilities of the test organizations at the test sites, has answered many questions relating to the economy of the sea, has opened up new knowledge of the life zones of coral atolls, and has reshaped in important ways the basic concepts of biological science.
