Objective
letermine at long range the period, amplitude, velocity,
and azinuth of acoustic waves from atomic explosions.
6.2.2
Erocedine
Generally, the method which will be used consists of a microphone capable of detecting slight variations in atmospheric pressures
(low frequency sound) caused by atomic explosions thousands of miles
away. By placing’ several microphones in a pattern, and recording
the "sounds" from: each separately on a time record, it can be seen
that an azimuth, or the-direction of the explosion, can be determined.
If several such stations, | great distances apart, each get an azimuth
on the explosion, its position can be plotted by triangulation.
Further, period, velocity, andamplitude can be determined. Stations
will be located within and Without the United States.

Objective
To obtain data based on physical, chpriical, and radiochemical
analysis of gaseous and particulate material yssociated with airborne
atomic debris following the explosion of an tomic weapon. These
data are used as calibration or reference points;fin evaluating
similar data obtained by analysis of atomic debrig whose origin
resulted from nuclear explosions of unknown origin, composition, and
design.
