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 (> 750 m) 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 and analysis [3]; - 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.
