Abstract : This patent discloses a subseafloor simulator for measuring acoustical and other physical properties of sediments at temperatures and pressures that simulate the real ocean environment. A pressure chamber has a porous piston to exert a required overburden pressure to simulate the weight of the mineral grains. An inlet port allows the fluid pressure inside the pressure chamber to be independently controlled. Acoustic and thermal transducers are mounted on the bottom of the pressure chamber. Electronic equipment is used for the acoustic and thermal measurements and the measurement of sample pressures and temperatures. A circulating thermal bath controls the temperatures of the sediment sample and the pressure chamber.
