Underwater sampling apparatus for collecting uncontaminated samples from an underwater environment at in situ pressure includes a sample chamber (10) in which the sample is to be collected, and a lid chamber (16) in hydraulic or pneumatic communication with the sample chamber (10) for defining a controllable interface between the sample chamber means and the underwater environment. The lid chamber (16) includes a stack of lid-chamber-defining plates (20, 24, 28, 38, 40, and 42) coupled together to form a unitary whole and a lid (8) movable between a closed position sealing the sample chamber and an open position in which the sample chamber (10) is open to the undersea environment. Motion control element moves the lid means between the open and closed positions.
