IVY, which had not previéysly been observed by ionospheric studies on
GRESUHUUSE, BUSTER, and TUMBLER-SNAPPER. This phenomenon was the
apparent increase in height: of.the F-2 layer and associated effects,
sginning about the time the Sonic wave from the blast would have
cached the ionosphere. It i8@esirable to establish a cause and
effect relationship for this }phézomenon. The effects on the ionosphere
of atomic detonations have possible-ap lication in long range detection
and ionospheric research as well ask edictions of radio transmission
disruptions.

aA repetition of the IVY experiment will be conducted with some
extension. Recorders will be operated at sites.located on opposite
sides of the blast for the Bikini shots, and (oh‘the same side but at
different distances, for the larger Eniwetok|ishdt. For the smaller
Sniwetok shot, one recorder will be operated iin the vicinity of the
test site, and one at some distance from the site.!| In addition sonic
equipment, capable of responding to periods as long! as 10 min, will be
operated in order to correlate sonic and ionospherjic effects.

The final results will be in the form of photograp vic filn
records of oscilloscope traces. The special camera used is as
tegral part of the ionosphere recorder.
