EVS-EN ISO 16665:2014

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 (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.
