slightly north of Eniwetok Atoll and did not coincide with
the center of greatest total radioactivity which occurred
approximately 110 miles due north of Eniwetok Atoll (21).
The C057 /zn©5 ratios decreased with increasing distance in
all directions from station 42.
The ratios of Co-!/Fe5> for the five plankton samples
are shown in Figure 4c.
