Water quality. Guidelines for quantitative sampling and sample processing of marine soft-bottom macrofauna. | Status: Current, Under review

1 Scope This International Standard provides guidelines on the quantitative collection and processing of subtidal soft-bottom macrofaunal samples in marine waters. This International Standard encompasses:

1. a) development of the sampling programme;
2. b) requirements for sampling equipment;
3. c) sampling and sample treatment in the field;
4. d) sorting and species identification;
5. 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 (see Reference [9]);
• — 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.
