An alternative to sampling porewaters to evaluate fluxes of nutrients and contaminants at the sediment-water interface is the use of a benthic flux chamber. Benthic flux chamber is essentially a container enclosing sediment and a small volume of overlying water that is incubated for periods lasting from a few hours to several weeks. During this time, concentrations of nutrients and contaminants in the overlying water are monitored at regular intervals, and changes indicate the direction and proportion of their fluxes; an increase in concentrations indicates a flux coming out of the sediment, while a decrease shows a flux into the sediment.
