considerable equinment, Of the buoys recovered fallout data were obtained from only 20 on Shots 1 and 2. vata were obtained on the currents in the vicinity of the two atolls, These data alone.with similar data from IVY are included in . ppendix H. 2e3e3el Shot The array planned for the first shot is shown in Figs. <.5 and 2.6. This wus consijered to be a reasonable effort based upon rehearsal experience. Heavy seas prevented plac:ment of all except the portion shown in Fiz. <.6. This citempt to sample the fallout was unsuccessful because the prizary fallout occurred in another sector. This failure indicated the importance of huving a 360° array around ground zero. Redetee Shot 2 The originul plan for Shot 2 called for a complete 360° array similar to thet planned for Shot 1. A portion cf this plan was executed tvice but in esch cause the shot was deferrei for an indefinite period. The buoys plzced cn these occasions were lest. «an alternate slan which required less time to implement was developed for use in case notice of the shot date was given too near shot. time to permit laying the uriginal urray. This alternute plen was used for Shot 2. See Fig. 2.7. 2ededed chot 4 The buoy urray and cetuils of the operation plan for Shot 4 cre given in Appendix a. This plun was successfully carried out on the basis of a firm schedule for the fourth test. However the effort was nullified by « very lat: deferment of the shot. were r covered, Cnly 7 of the 26 buoys When the shot finally did occur no buoys were in the orlimcury fullout zone, Bele 04 shot 5 Buovs were iuid in two separate attemots to d:cument fallout on Shot 5, The tirst array was cimilar to that employed for Shot. 2 (Fiz. 2.7). The cecond was intended to augment the first following a eL-hr delay of the test. Further deferment ..llified this effort, also.
