-SEPRETVIII. MARINE BIOLOGY SURVEY
An extensive program for the study of the contamination
of Pacific Ocean areas is planned.
may be considered in three parts:
a. Weapons Effects Test.
This ocean study program
Program 2 of the weapons
effects test effort will be concerned with fallout.
Project 2.62 of this program is known as oceanographic
analysis of fallout contours.
This project will be con-~
ducted by Scripps Institute of Oceanograph.
Fast ships
will enter the fallout area as scon as possible to take
samples for analysis and to measure vertical penetration
of the contamination over wide sea areas,
In addition,
the Scripps vessel "Horizon" will obtain numerous water
and plankton samples for analysis.
b. Radiobiology Marine Survey.
The Division of Biology
and Medicine of the AEC has recently requested that a
ship be provided to make two cruises in the vicinity
of the Pacific Proving Ground.
The first cruise will be
made about a month after the first shot.
The second
.
“cruise will be made after the last shot.
Each cruise will
traverse the sections indicated con the large chart.
(Radiobiological Survey Chart) During these cruises,
samples of plankton, fish and water will be collected
every 25 nautical miles at varying depths.
The Division
of Biology and Medicine believes that the radioblological
survey of marine life will be of great importance as a
basis for factual public statements concerning the extent
of radioactivity in the sea and marine life near the PPG,
and for advice to both Japanese and American fishing
interests,
ec. Other Marine Surveys.
The International North
Pacific Fisheries Commission is planning a large operation
this summer to study the distribution of salmon and other
fish.
Ships, both commercial and research, from Japan,
Canada and United States will participate. None of these
ships will enter the area north and northwest of the
Pacific Proving Ground, outside the Danger Area, where the
greatest fallout intensity. was noted after Operation Castle.
Our information on this International Survey was obtained
from Dr. Boss, Division of Biology and Medicine, AEC,
IX. POST SHOT AERTAL SURVEYS
After each shot of the Redwing series, aircraft will track
the radioactive cloud so that we will know if unexpected wind
changes are carrying significant fallout into populated areas.
Tn addition, aircraft with monitoring equipment will fly over
populatedareas south and east of the Pacific Proving Ground to
detect any contamination on the land masses and on the surface
of the sea,
This area will be searched after each shot to make
sure that no contamination has fallen near the populated atolls
east of Bikini.
The heavy line shows flight pattern ABLE for one
survey which will be made after each shot.
Other flight patterns
have been prepared and will be flown as the situation requires.
