| Definition | A frameless reversing water bottle with reversing thermometers that is used to collect water samples. The bottom of the bottle is clamped to a wire and the top of the bottle is held to the wire by a catch. It has independent hinged lids at each end which are held open against an internal spring when the bottle is deployed. Once the bottle has reached the target depth a messenger is dropped down the wire and hits the catch. The lids close and the bottle falls through 180deg, pivoting on the bottom clamp. This action reversed the thermometers, which are housed in a frame attached to the bottle. | ||
