适用范围：The procedure described in this European Standard is based on the standard settling technique as defined byUtermöhl in 1958 [31]. It describes a general procedure for the estimation of abundance and taxonomiccomposition of marine and freshwater phytoplankton by using inverted light microscopy and sedimentationchambers, including the preceding steps of preservation and storage. Emphasis is placed on optimizing theprocedure for the preparation of the microscopic sample. Many of the general principles of the approachdescribed may also be applied to other techniques of enumerating algae (or other entities) using a(conventional) microscope, some of which are described in Annex E. This guidance standard does not coverfield collection of samples or the analysis of picoplankton, quantitative analysis of free-floating mats ofCyanobacteria or specific preparation techniques for diatoms.
