The ARL:UT Subseafloor Environmental Simulator.

Abstract

An instrument has been constructed to simulate the natural environment of the subseafloor so that acoustical and thermal measurements can be made on a sediment at temperatures and pressures that duplicate in the laboratory those found in the natural environment. Hydrostatic pressures to 5.2 times 10 to the 8th power dyn/sq cm can be achieved by the instrument to simulate actual sediment pore pressure. Frame or overburden pressure can be exerted on the sediment up to 1.7 times 10 to the 8th power dyn/sq cm. Specimen temperature can be regulated from 0C to 75C. The instrument includes transducers and electronic equipment to make shear wave and compressional wave acoustic measurements as well as thermal conductivity measurements on the sediment at selected temperatures and pressures.
