A. Marshall and Caroline Islands. - The base for this operation {s the Eniwetok Marine Biological Laboratory. Areas from which
samples are to be obtained include Eniwetok, Bikini, Taongi, Uterik,
Rongelap, Ponspe, and Truk, or nearby atolls. These areas have been

sampled previously except Taongi, which is added because Taongi
appears to be in the path of a northeast surface current from the
Bikini area, as shown in a 1956 paper by Uda et al. Four people
can accomplish this mission in about 30 days. The pre-test survey
should be completed not later than five days before the first test,
and the post-test survey could begin within 4 week or two of the
completion of the testing program.
B. JPaley-Seipanarea. - This operation is based at the Koror
Field Laboratory of the Vanderbilt Foundation in the Palaus, and
does not require field support from the Task Force. The islands
at which samples are to be obtained include Saipan, Guew, Ulithi,
Yap, and Palau. These islands, from 1100 to 1700 miles west of
Eniwetok, ers in the path of the main flow of the North Equatorial
current from the Bikini-Eniwetok area.
One pre-test and three post-
teat surveys are to be made within one year of the testing program,
but eat the time which the surveys are to be aada can be estimated
|
better after completion of the analyses of the Redwing samples.
Four people and about 25 days are required for each survey.

Buring che testing progrem no surveys
would be wade other than requested for an emergency situation,
such as occurred on March 1, 1954. Two mem at Enfwetok, working
on special problems, would stand by during the testing operation
for this service.

The cceanographic program has been
changed from the plan submitted in February 1957, because a suitable
vessel was not availeble. resent plans call for a two-part oceanogrephic survey and, tentatively, a cooperative tuna sampling program
with the Japanese as a substitute for the combination oceanographic
and fishing cruise originally planned.
The first part of tha oceanographic survey will be in cooperation with
the Office of Naval Research. Using the Hydrographic Office vessel the
“Rehobeth", a week to ten day cruise will ba made to determine the exiating
levels of contamination in the plankton and water near the test sites prior
to the initiation of Hardtack.
Inmediately following the Wahoo event, the
Rehobeth will be used to follow the contaminated water westward from the
test site for a period of two to three weeks. During this cruise, ONR will
obtain the physical~oceanographic data and the University of Washington will
evaluate the contamination in the water and plankton.
