Land Stations
At Bikini, the islands of Able, Fox, How, Love, han, Groce,
Uncle, William, Yoke, and Zebra, were used for sampling and obtaining
gamma field measurements, Stations consisted of concrete emplacements
with instruments installed in and about them.
At Enivetok, the islands of Irene, Bruce, Yvonne, Wilma, Leroy,
Alice, Janet, and Nancy were used for sampling end for obtuining gamma
field measurements. where possible, st-.tion emplecements remaining frem
IVY fallout sampling were utilized; otherwise inctriments were pleced in
the open and suitable tie-down arrungezents improvised.
Stations were estublished on the following outlying islands:
Rongerik, Kusaie, Majuro, Ponape, Wake, Guam, Kwajalein, and Johnson.

Lagoon Stations
Rectangular-grid arrays of stations were established for
lagoons of both test atolls, as shown in Figs. 2.2 and 2.3. These ccnsisted of anchored buoys to which rafts were attached (see Fig. 2.4).

campling in the open ocean was accomplished by means of free~-
