"Uptake rate (hourly) of carbon {primary production CAS 7440-44-0} per unit time per unit volume of the water body [particulate >2um phase] by isotope-labelled tracer addition, on-deck incubation at simulated in-situ light level, cascade filtration and counting residue and summation of size-fractionated values"@en . . "SNCURAAC" . "Measurements made by radiotracer doped experiment, incubation at simulated in-situ light level, followed by counting of particulates collected on a cascade filter down to 2um and summing the size fractions. Rate normalised by dividing the total uptake by the incubation duration in hours." . .
