This standard provides guidance for marine biological surveys of supralittoral, littoral and sublittoral hard bottom for environmental impact assessment and monitoring in coastal areas. The standard encompasses surveys down to 30 m depth, which is the practical depth limit for scuba diving. The standard comprise of: - development of the sampling programme; - survey methods; - taxon identification; - storage of data and collected material. The standard specifies the minimum requirements for environmental monitoring. The methods are limited to surveys and semi-quantitative and quantitative recording techniques that cause little destruction of the fauna and flora. In practice, this refers to direct recording in the field and photography. Sampling by scraping off organisms, use of a suction sampler etc. are not covered in this standard, but such techniques can be used as a supplement, for information on small-bodied taxa or those that live hidden. For sediment sampling in marine areas refer to EN ISO 5667-19. For surveys of sub-littoral soft-bottom fauna see ISO 16665.
