Standards on Marine Biological Investigation Published standards: EN ISO Water quality - Guidelines for quantitative sampling and sample processing of marine soft-bottom macrofauna (2005) EN ISO Water quality - Sampling - Part 19: Guidance on sampling in marine sediments (2004) Drafts: prEN ISO Water quality - Guidance on marine biological surveys of littoral and sublittoral hard bottom prEN Water quality - Guidance standard for the routine analysis of phytoplankton abundance and composition using inverted microscopy (Utermöhl technique)
EN ISO Soft-bottom macrofauna Guidelines describe quantitative surveys of sublittoral soft-bottom fauna in coastal areas and on the shelf. all areas of a floor where is possible to collect samples by grab (or box core) are considered as soft bottom limited to sampling (and analysis) of macrofauna which retained on a 0,5 mm to 1,0 mm mesh screen
EN ISO Sampling in marine sediments Guidance for the sampling of sediments in marine areas for analyses of their physical and chemical properties for monitoring purposes and environmental assessments. It encompasses: sampling strategy; sampling devices; observations made and information obtained during sampling; handling sediment samples; packaging and storage of sediment samples.
prEN ISO survey of hard bottom The standard covers: – development of the sampling programme; – survey methods; – taxon identification; – storage of data and collected material The standard specifies the minimum requirements for environmental monitoring.
