For NECTAR at Enewetak, Holmes & Narver and buoy recovery. After recovery, (H&N) handled the mooring the buoys were placed on a barge and taken to a decontamination area. Staffing: Twenty-eight TG 7.1 personnel were definitely associated with this project, although an exposure record was not located for one of them. Of the remaining 27, the distribution is as follows: 1 ci- vilian from ONR, 2 civilians from NRL, 4 civilians from DTMB, 5 military from 1090th, 1 military from 845lst, 1 civilian from SC, and 13 from NOL (1 military and 12 civilians). Project Report: Reference 45. Project 1.5 -- Acoustic Pressure Signals in Water Agencies: Operations: Office of Naval Research Bureau of Ships (BuShips) (ONR) Observations were made at several Underwater Sound Trans- mission Experimental Facilities (USTEF) stations in the Pacific and Atlantic oceans to detect long-distance transmission of underwater sound. Sites were remote from the test area and there is no indica- tion that project personnel visited the PPG. Shots: ROMEO, UNION, YANKEE (Bikini); NECTAR (Enewetak). Radiation Exposure Potential: Project Report: None. Reference 46. Project 1.6 -- Water Wave Measurements Agencies: Operations: Scripps Institution of Oceanography (SIO) Sioux Underwater gauges were used to record hydrostatic pres- sure vibrations in Bikini Lagoon. Divers placed some instrumentation, and recovery was made by LCM, buoy boat, and helicopter. Inundation indicators were established at Ailinginae Atoll to measure the inundation of the land.
