The Bikini boat pool had a sharply increased wor k- load in order to provide transportation between the shipboard living quarters and work sites. All ships would evacuate the Bikini Lagoon before all scheduled The movement of fleet units out of Bikini Lagoon during evacuation m hots. neu- vers for postponed attempts did have some advantage because it helpe flush out the contaminated lagoon waters from the ships' with open ocean water seawater syptems (Reference 16, p. L-3), preventing a large bui Ldup of radioactive contaminants within the systems. ROMEO ROMEO, the second CASTLE test, was the first barge-mounted, wat Surface detonation. Because of concern that the experiments being e=- pared at Eneman for shot KOON might suffer blast damage from ROMEO, its scheduled site was changed from south of Iroij which to the BRAVO crater, was a greater distance from Eneman. Preshot Preparation ROMEO was ready to fire on 13 March, and the sequence of sea and air searches, weather analyses, fallout predictions, briefings, and adv SOry messages to the Commander-in-Chief of the Pacific Fleet Unacceptable weather delayed the detonation for 2 weeks. (CINCPAC) b an. During th S pe- riod, the task force maintained an 18-hour standby capability to co duct the test. The weather-caused delays had two consequences for subsequent t sts. First, the method of conducting air searches for the protection of ran- Sient shipping was changed when it was determined the search plan w s not flexible enough to cope with the large geographic shifts in the lon “range fallout forecast that could occur between successive tentative shot days. The new procedures included specification of an expanded hazard zon Green, see Figure 16) to control shipping, and the use of three or 250 (Area ore
