An unmanned underwater vehicle 21 comprises an outer hull (10, Fig 1) defining an internal volume, a pressure communication channel (14, Fig 1) between the internal volume and the exterior of the outer hull, arranged to control the pressure in the internal volume based on the exterior pressure and a buoyancy and trim control system (18, Fig 1). The vehicle further comprises a probe 26 provided within the internal volume of the vehicle and a port at the bottom side of the vehicle, providing a channel between the internal volume and the exterior of the vehicle, for the probe to extend through the port for collecting material or data. A method of collecting samples or data using an unmanned underwater vehicle with a data and material collection probe is also disclosed.
