Equipment Used
|
|
|
Purpose
|
Provide geological expertise to H.L.Hunley archeologists to reveal and interpret
the sediment layers around the H.L.Hunley submarine and the USS Housatonic
warship.
|
|
|
Information to be Derived
|
Stratigraphic interpretations, photographs, and subsamples for lab analysis of
sedimentation rates using Pb210
|
|
|
Summary
|
Collected seven vibracores total: five for our geologic interpretation and two
to be sent off for stress test analysis. Collected May 25, 1999
|
|
|
Notes
|
The coordinates were considered top secret so they were not kept by the USGS.
The water depth was not kept either for protection from scavenger divers.
Bradford pneumatic vibrator, powered by two air compressors delivering 35
standard cubic feet per minute (scfm) at 100 pounds per square inch (psi) each.
The vibracore rig is used aluminum barrels 3 inches in diameter by 20 ft in
length. Brass core-catchers were riveted at the base of each barrel to ensure
complete recovery of the sediments.
