= of samples from depths were taken for Project 2.63, RESULTS Preliminary examination of the fallout data gathered by survey ships indicate that the fallout area extended approximately 150 miles along an axis of about 330 degrees True. The east and north boundaries were remarkably sharp and gave a pattern of about 90 miles between the axis and the eastern boundary, The west boundary was so diffuse that it could not actually be distinguished but merely appeared to be scattered extensively westward. Results of the postshot lagoon survey and the moored-skiff instrument recovery await further examination, CONSIUSIONS Specific conclusions await further data reduction. Inter- comparison of the measurements mate by various instruments on the different survey vessels of various projects show good correlation and the partially assembled data gives a coherent fallout picture, This correlation was carried out by Program 2,
