Abstract
Experiments on sizing seston and nylon rods in Coulter apertures of different sizes showed that a major difficulty in obtaining a continuous particle-size spectrum for lake seston is the presence of long, thin algae which are significantly undersized unless their lengths are shorter than aperture length. These fibers affect not only the choice of the largest aperture tube required but also the combination of aperture tubes necessary to obtain a continuous particle-size spectrum. Methods are given for selecting aperture tubes and blending the data obtained from them to give a best estimate of the continuous particle-size spectrum.Key words: Coulter counter, multitube technique, lake seston, particle-size analysis, aperture tube selectionThis publication has 0 references indexed in Scilit:
