ABSTRACT:
A method and apparatus for maintaining oxygen levels in an isolated volume f fluid (e.g. water) is provided. The method and apparatus are adaptable for use with a benthic flux sampling device and rely upon periodically measuring the oxygen concentration in the isolated volume with an oxygen sensor system, monitoring the oxygen sensor system with a control unit, and automatically dispensing oxygen into the isolated volume of fluid with an oxygenation system to maintain a predetermined constant level of oxygenation that corresponds to the ambient.
