DIN EN 15972:2011-11

This European standard provides guidance for sampling, preservation, storage, quantification and qualitative analysis of phytoplankton from marine waters. Guidance for quantification is limited to use of light microscopy with phase-contrast and epifluorescence. The standard comprises: development of the sampling programme; requirements for sampling equipment; procedures for sampling and treatment of samples in the field; methods for quantification; qualitative analysis. The standard provides minimum requirements for environmental monitoring.
