Program III -- Wave Motion Oceanography


 * Agencies: Smithsonian Institution
 * U.S. Geodetic Survey
 * U.S. Fish and Wildlife Service
 * Woods Hole Oceanographic Institution


 * Operations: This program had 20 separate projects to measure and record wave motion and to study detonation effects in the area of Bikini Lagoon. Some instrumentation was placed on the bottom of the lagoon, some suspended in the water from target ships, and some on nearby islands.


 * Staffing: Program III personnel were from the Wave Motion and Oceanography group of the Instrumentation Division. Ninety-three personnel were assigned, 30 of whom were badged. Recorded exposures during the periods they were badged were all less than 0.5 R.


 * Removal of instrumentation from target ships, particularly after BAKER, exposed personnel to radioactivity on the ships. Removal of instrumentation from the lagoon bottom also exposed recovery personnel to some radiation after BAKER since the water in some areas of the lagoon was radioactive. However, recovery times apparently were relatively short and this minimized radiation exposure. Some islands were also contaminated after BAKER and instrument recovery there created exposure potential depending on recovery date and stay time.

Program IV -- Propagation of Electromagnetic Waves


 * Agencies: Los Alamos Laboratory
 * Army Air Forces (AAF)
 * Electronics Group
 * National Bureau of Standards (NBS)
 * Federal Communications Commission (FCC)


 * Operations: There were 18 separate projects in Program IV. Radars and radios, some operating at detonation time, were placed on selected islands at Enewetak, Kwajalein, Bikini, and on selected target ships. Television cameras were installed on B-17 drones and controllers. Two projects provided timing and firing signals for BAKER. Four projects measured electromagnetic properties from remote locations in Hawaii, Germany, Manila, Alaska, and the United States. One project telemetered air- and water pressure readings from target ships to receivers on Avery Island.


 * Staffing: Personnel from the Electronics Group of the Instrumentation Division accomplished all the projects in this program except for IV-9 through IV-13, which were done by Los Alamos Laboratory and the Army Air Forces.
