effort to support this project to the fullest extent, however, in
a future operation of this type provision should be made far permanent assigumernt to the preject group of the required support
ahipe, Preject 1.6 ecndusted by the Boripps Institution ef Geeanegraphy maintaincd several flicating lageon stations ent a number of
shore recording stations for measuring water wave heights. Their
Suppers requirexents were scusuhat modest in comparison with those

of Project 1.4 and they were able to maintain their stations in
readiness for the shosa, in spite of the excvscive delays in the
abote, with the ascigument of one spsoially modified Loh, in

The croral? results obtained by Frogran 1 were sasewhat lecs than
had been enticipated dus to the extreme variation in yields of
several shots, the cancellation of one shot and the change in the
Zoontion of several of the vhote.

In Progran’2, measures

uente were nade of the tote! gmama radiation on ali shots ant the .
gana rediation versus time on three shots, neutron flux and speo~
trum on 3 shots and fall out on all shots. Meneurements of total
gamma presented ne unuscal operational prevlems since these measuresents were made by neans of conventional fils badge dosimetry,
The equipment for meaguring the ganem rate aa a function of tim
functioned satisfasterliy on the first shot, however, the extremly
high yield of this shot net only damaged nany of the measuring sta-~
tions but alee caused a fire in the adainistrative compound on Tare
which destroyed a large proportion of tho projects spare equipment.
For this reasen, participation in succeeding shots was extremly
lisited and very few stations were activated, The neutron measuree
monts were reasonably suseesaful on the first two shots although
considerable damage was dene to the close-in statione and residual
contunination prevented early recovery, thus decreasing the usefulnese of the information, The fall out program presented the most
difficult operational problem in the effects program.

Fall out

measurements were made in three genere] areas; within the lagoons,
en evallable land masses and in the open sea.

Measurements within

the lagoon vere made by means of anchored floating raft stations
equipped with approprinte collector devices, The extremly rough .

water of Bikini lagoon resulted in the loss of a mumber of etations

even befors the firat shot due to an unsaticfactory anchoring arrangement. The high yield of the Mrst ehct overturned many of the
rafte, thus destroying thelr usefullness for collecting fall out
