Abstract:
Simultaneous determinations of the microplankton biomass by direct microscopy and by measuring concentration of adenosine triphosphate (ATP) in samples from different depths of the Eastern Pacific revealed considerable differences between values obtained. With the exception of 3 of 62 determinations, the biomass determined from ATP exceeded that measured by microscopy; the latter averaged about 10% of the former for the region as a whole. This sharp difference is largely due to underestimation of ultramicroscopic cells by direct microscopy and to substantial variations in the factor used to convert ATP concentrations to cell biomass.
