Results from the reverse-flow concentration method used to determine community plankton respiration vary significantly because of metabolic inactivation or losses of a portion of the concentrated sample during the filtering process. These losses seem to be nearly constant at concentrations greater than 150X. The within sample coefficient of variation is 20-40% and is primarily a result of clumping and inadequate mixing before subsampling. A rapid processing of the samples is critical for best results.
