ÖNORM EN ISO 16665

This International Standard provides guidelines on the quantitative collection and processing of subtidal soft-bottom macrofaunal samples in marine waters. This International Standard encompasses: a) development of the sampling programme; b) requirements for sampling equipment; c) sampling and sample treatment in the field; d) sorting and species identification; e) 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 (>750 m) or offshore sampling; - in situ faunal studies, e.g. recolonization assays; - non-benthic organisms caught in the sampling device; - estuarine sampling; - intertidal sampling; - meiofaunal sampling and analysis; - sampling by dredge and sledge; - self-contained underwater breathing apparatus (SCUBA) sampling; - statistical design. Accuracy of position fixing is determined by the geographical area, equipment used and survey objective.
