Abstract

DURING a series of experiments designed to determine the relative sizes of tropical pelagic phytoplankton labelled with carbon-14, it was noted that the retentive capacity of ‘AA Millipore’ membrane filters varied considerably in three experiments as shown by retention of passed material on a fine filter (Table 1). It seemed surprising that a membrane filter with a pore size of 0.8µ would pass significant amounts of carbon-14 activity, bound in phytoplankton.
