The effects of water volume filtered and number of filters used on the observed concentrations of particulate nitrogen and carbon in marine waters were examined using 47‐mm, 0.8‐ µ silver filters. The best procedure is to filter through single filters using gravity when possible. The optimum volume for filtering depends on the concentration of particulate matter in the sample and generally is between 1 and 10 liters. Adsorption of carbon to silver filters appears negligible.
