Abstract : An apparatus for controlling the depth of an object submerged in a liquid medium includes a sealed chamber means, joined to the object, which retains a working fluid and which has a variable external volume for displacing variable amounts of the medium. The apparatus further includes a heat transfer device for controlling the external volume of the chamber by heating the working fluid to increase the external volume, and by cooling the working fluid to decrease the external volume.
