Low photosynthetic rates and reductions in chlorophyll concentrations were observed in incubations of samples taken with a 30-liter Niskin sampler during productivity studies of oligotrophic waters in the Indian Ocean. By contrast there appeared to be no effect on community respiration. The rates of photosynthesis were 5-fold to 10-fold greater in samples taken with Teflon-lined 10-liter GoFlo bottles, and there was no systematic loss of chlorophyll. The central rubber cord of the Niskin sampler was identified as a potent source of contamination.
