time to fly the aerial survey. This was usually only a few days at eachatoll, and the scope of the terrestrial and marine efforts was determined accordingly. Though the Wheeling provided an excellent base for the aerial survey, operating from a large ship that cruised a considerable distance from shore scope of the terrestrial and marine surveys because of the reach the atolls and islands in the small boats. lifting capacity of the helicopters, be small and limited the time required to Also because of the limited the terrestrial support equipment had to the rate of sample collection and the ability to reach certain islands or areas of islands was reduced. The second helicopter aboard ship was used when possible to help distribute equipment and marine and terrestrial crews around the atolls. However, a certain amount of downtime was required for each helicopter and it was necessary to always have one flying the aerial survey. Thus, using helicopters for support of the marine and terrestrial surveys even for limited periods required careful planning. in number It was a considerable effort for the Navy mechanics, reduced from the normal condition. complement, to keep the helicopters in operating During the second leg of the survey only one was usable and it was dedicated to the aerial survey. Thus only the small boats were available conduct the terrestrial and marine helicopter was available and surveys. because of During the adverse third weather leg to the second conditions, became essential to the terrestrial and marine programs. We attempted to collect the maximum possible number of terrestrial and marine samples from as many islands as possible with the time available. All samples was were returned conducted both at to LLNL for processing LLNL and contract and the laboratories. analytical The procedures work for sample collection and the number and type of samples collected by island and atoll are summarized here. In addition we have listed the total number of analyses by radionuclide of the samples collected during the survey. This report terrestrial is the and marine first surveys. independently by Ec&G./ of a The series summarizing aerial survey the data results has been In other reports of the series we will from the published address the radionuclide concentrations in cistern water and groundwater and the estimated doses via ingested water; the associated estimated the radionuclide concentration in marine doses from the marine pathway; the species and radionuclide concentration in soil, plants, and animals at each of the atolls and islands and the estimated doses via the terrestrial foodchain; the analytical methods and
