The initial field survey was contemplated for the period October 12- December 6, 1972. The first week of this schedule was started, but not completed, when Typhoon Olga caused a suspension of activities. Subsequently, it was necessary to revise and reschedule the survey to account for weather factors and logistic limitations. An aerial radiological and photographic survey of the atoll was accomplished November 8-25 during the period of minimal logistic support. Survey activities were resumed during the week of November 27 on a revised schedule and will now extend to mid-February 1973. The AEC radiological survey now appears to be progressing smoothly and collected samples are being returned to the CONUS for analysis. Data to date, based mainly on the results of the aerial survey, appear to be generally consistent with earlier knowledge and expectations. Lh GtEt pha A.
