DIN EN ISO 16665:2014-06

This International Standard provides guidelines on the quantitative collection and processing of subtidal soft bottom macrofaunal samples in marine waters. This International Standard encompasses: - development of the sampling programme; - requirements for sampling equipment; - sampling and sample treatment in the field; - sorting and species identification; - storage of collected and processed material. This International Standard does not specifically address the following, although some elements may be applicable: - bioassay sub sampling; - deep water or offshore sampling; - in situ faunal studies, e. g. recolonisation assays; - non benthic organisms caught in the sampling device; - estuarine sampling; - intertidal sampling; - meiofaunal sampling; - sampling by dredge and sledge; - Self Contained Underwater Breathing Apparatus (SCUBA) sampling; - statistical design. This International Standard applies to all areas of the sea floor where it is possible to collect faunal samples by a grab or coring device. For practical reasons, this applies to animals retained on a mesh screen of 0,5 mm or 1 mm aperture size.
