samples by force of suction is attached to the device. During ascent, pressure is maintained within the chamber by use of pressurized water. Upon surfacing, samples can be observed, filmed, and/or photographed through transparent view ports in the device. Due to fluctuations in atmospheric pressure and temperature recorded pressures during ascent and at the surface may ranged from 74%-111% of the natural pressure at sea depth. The device set a record for the deepest live-fish capture under pressure when it captured a
