ISO 16665:2014 (R2019)

ISO 16665:2014 provides guidelines on the quantitative collection and processing of subtidal soft-bottom macrofaunal samples in marine waters. ISO 16665:2014 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. ISO 16665:2014 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.
