at 90 degrees to ground zero. A signal cable was
connected to the gages and run back to recording Station 118.01. A total of 19 cubic yards of
concrete was placed.

This station was a concrete pit 12’ x 4’ x 4’
deep. The roof was of planking and covered with
earth. The recording equipment in this station
was used for instrumenting the 116 and 117
series stations. A 16’ x 16’ tent provided weather
protection over the pit when it was open prior
to D-Day. Timing signals and a blue box were

The Stations consisted of stable wooden
platforms size 18’x24’ on a steel frame supported
on four 12” H-piles. Required elevation was plus
12 feet, which placed the platforms about 9’
above the coral surface of the reef. The piling
for Station 130.01 was driven into the coral to
refusal at an average penetration of 13.5 feet,
and for Station 131.04, the piling was driven to
a depth of 25 feet. Station 130.01 was located
within a tolerance of plus 1000 feet to minus
500 feet and Station 131.04 was located to a
tolerance of plus or minus 200 feet.
The stations were fitted with a fender
system on one side and mooring cleats which
facilitated boarding the platform from marine
craft. One side of the platform had a “lift out”
type railing, while the other three sides had removable bolted railing. Eyebolts were installed
around the platform as tie points for rocket
launchers.
Scientific power requirements were estab-
installed. A total of 6 cubic yards of concrete
was poured.

These stations were identical to those of the
117 series on Pearl with the exception that the
gage mount at 90 degrees to ground zero was
not required and the signal cable was run back
to Station 3020. A total of two cubic yards of

For Station 130.01, a standard 14’ x 14’
tent was erected complete with work bench,re-
ceptacles, and lighting.
Progress on these Stations was slow due to
the fact that the work had to be scheduled in
accordance with tidal and weather conditions.
During the construction of Station 130.01, a
DUKW carrying a welding machine was damaged and sank while approaching the construction
site. Operations were suspended until the equipment was recovered.
