A.
The
amount
and
nature
of
radioactivity
remaining in the lagoon water and on the reef and land
Structures of the atoll, wherever it exceeded normal
levels of radioactivity and cosmic rays.
Particular
attention to be given to that portion of the reef
between Amon and Bikini Islands; at a stage of tide as
nearly as possible that which existed 15 minutes after
Test B, to chart the exposed portion of the reef by use
of aerial photography.
B.
The concentration and kind of radioactive
materials in plants and animals of the area, and the
effects of radioactivity upon such organisms.
C.
Phystological, geological, and oceanographic
Studies
of organisms

reef-building
processes,
including the drilling of cores down to 1,000 and
perhaps 2,500 feet.
D.
Detailed observations (including photographic
recording) of ships sunk as a result of Test B, with
special attention to Saratoga, Nagato, Pilotfish, and
Apogon,
and
perhaps
Arkansas
and
Gilliam,

permitting.
Detatled structural
inspection of the
sunken vessels,
to
determine
the exact
cause
of
sinking; and to reveal minor structural failures such
as bent, warped, or ruptured plating and scantlings.
E.
Recovery of four instruments from Nagato, as
follows: one ionization gage, two linear. time pressure
recorders and one diaphragm type damage gage.
These
instruments, being watertight, were believed to
good
condition,
and
it
was
thought
recordings might be of considerable value.

Time permitting,
to attempt to locate a
section of LSM-60, believed to have been identified in
photographs, and to inspect this section thoroughly for
type of rupture, heat effects, and radioactivity.
