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.
