Project 2.62 - Fallout Studies by Oceanography Methois - F. D. Jennings
OBIZCTIVES
To understand the oceanography of the ocean area where fallout
is expected in order to extrapolate the observed fallout pattern back
to the equivalent land pattern.
To furnish oceanographic assistance
to the Task Force,
To measure the fallout raiioastivity and its chemical nature in
the water from a high air burst, a surface land burst, and surface
water bursts.
To calculate the equivalent lani fallout pattern.
To understand the nature of the transport and dilution of radioactive fallout material in the ocean to permit future surveys to acquire
a complete fallout picture from the least possible measurements,
To understand the oceanography of Rikini Lagoon as it involves
the circulation of contaminated waters, particularly the effluent
thereof and the occurrence of rapid transients of circulation which
may result in sudien redistribution of activity.
DESCRIPTION AND EXSTRIMTUNTAL PROCEDURE
The Bikini Lagoon was investigated using an instrumented trailer
aboarj a Navy Lou,
The project installed and maintained sixteen deep—moored skiff
stations in the fallont area between 19 and 30 miles from ground zero.
Recoriing instruments were installed on these skiffs to measure the
radioactivity as a function of time at depth intervals of 20 meters down
to 100 meters.
