It is essential to the understanding of the atomic energy testing program that studies evaluating biotic contamination keep pace with the changes in weapon design, materials used, and efficiencies obtained. Questions on Future Resurveys At a meeting with the staff of the Applied Fisheries Laboratory on August 20, 1951, Dr. Paul B. Pearson, Chief, Biology Branch, Division of Biology and Medicine, Atomic Energy Commission, asked seven Eniwetok resurveys. in a general way, (7) specific questions concerning Bikini- We have attempted to answer these questions presenting our viewpoints as based on past experience rather than projecting future studies into the discus- sion. 1. What data of importance are to be gained by the Laboratory and by the Division of Biology and Medicine from new resurveys? a. The most important contribution of repeated resurveys is a better understanding of living processes that can be obtained by evaluating the fauna and flora of Bikini and Eniwetok Atolls "tagged" with identifiable materials.
