Of a total of nine off-atoll projects, eight were sponsored by DOD. In general these were concermed with long range effects and used existing facilities within their own organizations: The projects involved in off-atoll activities were as follows: a. Project 1.2 - Acoustic pressure signals in water, with various stations in the Atlantic and Pacific oceans. b. Project 1.6 - Water wave studies, a project participating both locally and at stations at Midway, Wake, Guam and California. ._c, Project 4.1 - Biomedical studies, which were established at Kwajalein to study the effects of the inadvertant fall- out on the residents of Rongerik and Rongelap Atolls. d. Project 7.1 - Electromagnetic Fadiation Calibration, with atations in the United States, Hawaii, Alasza, Scotland, and Greenland. e. Project 7.2 - Detection of airborne low frequency sound, with stations in Japan, Hawaii, Alaska, Greenland and Germany. The four other projects operating off-atoll for which direct Support was arranged by this headquarters were as follows: a. Projects 2.5a, 2.5bd - Fall-out Distribution Studies at Kwa jelein, Ponape, Kusaie and Mauro, b. Project 17.1 lein and Ponape. Coptea/DOE LANL, 4-Olv. - Microbarography, with stations at Kwaja- 73 1 ne otf five of the off-atoll projects required no active or continuous support from this headquarters other than notification of shot delays.
