through the end of March 1980. After that date DNA will not search for or dispose of any further radioactive scrap.

Shell Collecting - An order was issued by the Commander, Joint Task Group proscribing the collection of living sea organisms, included shells with living inhabitants. This The purpose of the order was to conserve, insofar as possible, the fragile ecosystem of the Atoll reefs, The order was repeated to all personnel one to two times a month in the daily-bulletin. Shell collecting was permitted, however, provided the shell contained no living organism, It should be noted that the beaches on Enewetak are formed by bits of shell and coral and are primarily calcarious material; consequently it would be difficult to strip the beaches of shells. Perhaps a more appropriate interpretation of the information which was provided would be that the more desirable uninhabited shells had been collected. CY FURN: NVO, DOE FCZ, FC DNA
