ABSTRACT:
A device for increasing the oxygen concentration in a subsurface stratum of a thermally stratified body of water. The device comprises a flexible tube (13), which is surrounded by a flexible shell (12). Compressed oxygen-containing gas is introduced through first nozzle means (29) at the lower end of the tube and through second nozzle means (31) into channel means (34) between the shell (12) and the tube (13). There is an upward flow of water in the tube and a downward flow in the channel means (34) around the tube.
