- Director, DNA Ze to this activity, ERDA sponsors and PASO supports, a sumber of research activities, «.g., the ERDA experimental farm at Engebi (Enewetak Atoll). Marine Laboratory; For 2Z yeare the United States has maintained at Enewetak a field laboratory station which was ' esteallished as a part of the atmospheric test program. This laboratory, concerned initially with what we would describe today as environmental impact, has became a center of unique understanding of radiological pollution in a tropical marine environment. For an expenditure over the 22 years of about $1 millian, it has supported almost [000 investigators tn fieid research efforts. Nevada provides administrative and logistic support to the Mid-Pacific Marine Laboratory and is active in its program direction. Environmental Surveillance of the Marshall Islands: Many atolis and many tens of islands in the Marshalis were affected by fallout from atmospheric tests between 1946 and 1958. Nevada has been charged with responsibility for long-term monitoring of the presence, transfer, removal uptake and decay of the fallout residue, for assessing the significance to man of the radiation in his environment and for providing advice and assistance to Prust Territory authorities. We expect — this responsibility to continues for many years. ration the Marshall Islands Research Vessaly Nevada acquired, about two years ago, a ship which has been used very auccessfully to support a variety of research programs in the Marshalls. This research vessel, under operational control of PASO, has previded each year more than 1600 s@tentific man days on station in the Marshalls. It is based at Kwajalein and operated for ERDA by the Army's KMR contractor. Sincerely, Roger Ray, Aesistant Manager for Eavironment & Safety 1930
