Even then, however, the United States, in its response, did not return to testing in the Marshall Islands.

A rectangular aquarium was con- “ved in the center of the large main room which was un” three sides and open to the lagoon. A sea" system was installed, and living quarters were pro «iced for EMBL personnel and visiting scientists in a building across the lagoon road from the laboratory complex. _~Mithough adequate, this facility had one important drawback. Boat operations required the use of the utility pier at the northeast end of the island, making loading and unloading difficult. and necessitating the carrying of equip- " Ment and specimens between the pier and the laboratory. “559, another move was in order. this same year, the directo.ship of EMBL passed ; ~! irom Robert W. Hiatt to Vernon E. Brock, and then, a #4 months later, to Philip Helfrich. Helfrich continued as director until January 1, 1975. In 1969, military activities at Enewetak dictated eae another move for EMBL, this time to the vicinity of a large. three-story dormitory building which had been con- Structed on the ocean side, toward the middle of Enewetak Island. The new location was a complex of aluminum build: Previously used as library, recreation center, and 390m.

With about twice the space that had previ- ously been allocated, the new facility included a large general laboratory, a shop, photo darkroom, library, equip ment room, communications room, a dive locker, and a separate building for the storage of hazardous chemicals ° {Fig. 6}. In the early 1970s, EMBL acquired its own communication system, providing a voice and teletype link to the University of Hawaii. MOVES TOWARD RESETTLEMENT ’ The year 1972 brought significant political develop ments which were to have a lasting effect upon the future of the people of Enewetak and upon the fortunes of EMBL. Politica! status talks had been going on for several years between the government of the United States and representatives of the people of the Trust Territory of the Pacific Islands (TTPI). These talks were aimed at ultimate termination of the United Nations trusteeship over the Micronesian Islands (with the United States as trustee) and the establishment of one or more new and independent self-administering political entities. During the 1972 talks, responding to the pleas of the people of Enewetak for the return of their home islands, the United States took the first steps toward that return. In April, Ambassador Hayden Williams, the President's personal representative to the talks, was joined by High Commissioner Edward John- ston of the TTPI in a public statement. of U. S. intentions. It provided that military use of Enewetak would shortly be . completed, thus permitting the atoll to be returned to the administration of the Trust Territory, and that steps necessary to rehabilitate the islands for resettlement could then begin. | Later in 1972, the AEC’s Nevada Operations Office, using the resources of its national laboratories and contractors, mounted a massive radiological survey of Enewetak Atoll as a preliminary step toward cleanup,and rehabilitation.”These activities are described in official reports (U. S$. AEC, 1973;:U. S. DOE, 1982; Holmes and Narver, 1973; and U. S. DNA, 1975). Although EMBL did not participate directly in either the 1972 survey or the cleanup, the director and other scientists consulted and assisted in many ways. While applied science and eng} .eering were at work to restore the atoll, the basic studies of EMBL continued apace. Although this tiny, remote research station might have been overwhelmed by the enormity of tne cleanup effort (thousands of men, over 3 years, at a cost of more than $100 million), those respon-. sible in the AEC (now the U. S. Department of Energy) and the U. S. Defense Nuclear Agency (DNA), recognized the lasting worth of the science program and saw to it that the laboratory’s interests wereprotected. In 1978, the U. S. Coast Guard LORAN Station, . which had occupied a complex of buiidings at the eastern end of Enewetak Island, was closed. By agreement with DNA and with the people ci Enewetak, DOE obtained the
