A subice sampler is made of a length of tubing which can be tightly sealed at one end by means of a clamp. It is placed open end down through a hole in the ice, pressurized and sealed to maintain the water level below the ice base so that water inside will not freeze, and allowed to freeze in place. Water samples from beneath the ice are collected by releasing the pressure in the tube and withdrawing water with a small hand‐operated pump.
