Program VIII -- Remote Measurements


 * Agencies: U.S. Coast & Geodetic Survey
 * Carnegie Institute
 * National Bureau of Standards
 * Naval Research Laboratory
 * David Taylor Model Basin
 * U.S. Weather Bureau
 * University of Washington
 * University of Texas
 * Bartol Foundation
 * Mt. Wilson Observatory
 * Evans Signal Laboratory
 * Federal Communications Commission
 * Puget Sound Naval Shipyard
 * Army Air Forces (AAF)


 * Operations: This program consisted of 18 projects. Experiments were conducted at sites around the world to measure changes produced by the detonations. Measurements were made of tides, wave action, atmospheric reflectivity, atmospheric pressure, atmospheric ionization, atmospheric noise, radioactivity, and long-range radio waves. Only Project 14 used locations in the Bikini area, specifically Eneu Island and USS Kenneth Whiting (AV-14).


 * Staffing: Organizations involved in each of the projects are listed above. Names of individuals associated with these organizations cannot be separately identified. Except for Project 14, which had instrumentation on Eneu Island and Whiting, exposure potential was extremely low for everyone working with this program. The Eneu site was not contaminated after ABLE but the beach was contaminated after BAKER. Eneu was visited on 25 July (BAKER day) and all experiments removed during the afternoon. Three days later it was radiologically cleared and reopened for troop use.

Program IX -- Technical Photography


 * Agencies: Los Alamos Laboratory
 * Army Air Forces (AAF)
 * U.S. Navy
 * Technical Photography Group


 * Operations: There were 19 projects in Program IX associated with technical photography. Project 1, operated by Los Alamos Laboratory, used high-speed cameras to record the growth rate of the ABLE fireball. Half of the cameras were in a tower on Bikini Island and half in a tower on Eneu Island. Projects 2 through 7 use cameras mounted in six camera towers to observe water wavs, ship motion, burst location, light intensity, and record damage. There were two camera towers each on Bikini, Eneu, and Aomen islands. These six projects were operated by the Technical Photography Group of the Instrumentation Division. Projects 8, 9, and 10 consisted of technical photography from AAF planes. Cameras were mounted in B-17 drones, C-54s,
