Water quality - Guidance on marine biological surveys of hard-substrate communities (ISO 19493:2007)
ISO 19493:2007 provides guidance for marine biological surveys of supralittoral, eulittoral and sublittoral hard substrate for environmental impact assessment and monitoring in coastal areas. It comprises development of the sampling programme, survey methods, species identification and storage of data and collected material.
ISO 19493:2007 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 ISO 19493:2007.
Wasserbeschaffenheit - Anleitung für meeresbiologische Untersuchungen von Hartsubstratgemeinschaften (ISO 19493:2007)
Diese Internationale Norm enthält Anleitungen für marine biologische Untersuchungen auf supralitoralem, eulitoralem und sublitoralem Hartsubstrat zur Ermittlung von Umwelteinflüssen und zur Umweltüberwachung in Küstenbereichen.
Diese Internationale Norm beinhaltet:
das Aufstellen eines Probenahmeprogramms;
die Untersuchungsverfahren;
die Bestimmung der Taxa und
die Speicherung der Daten und die Lagerung des gesammelten Probenmaterials.
Diese Internationale Norm legt die Minimalanforderungen für Umweltüberwachungsaufgaben fest.
Die Verfahren erstrecken sich nur auf Untersuchungen und halbquantitative und quantitative Techniken, die die Flora und Fauna nur wenig beeinträchtigen. In der Praxis entspricht dies der direkten Erfassung vor Ort und der fotografischen Dokumentation. Probenahmen, bei denen Organismen abgekratzt oder durch Ansaugtechniken usw. gesammelt werden, sind in dieser Internationalen Norm nicht berücksichtigt. Solche Verfahren können allerdings ergänzend für kleine oder versteckt lebende Taxa eingesetzt werden.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

Introduction
Surveys of benthic marine algae and fauna on hard substrates represent an important part of marine
environmental surveys. The species composition, both in terms of the species present and their relative
abundances, is a result of the natural and anthropogenic environmental factors at the survey site. Natural
factors that influence species composition include wave exposure, depth, salinity, nutrient level, type of
substrate, slope, orientation, turbidity, current, temperature and grazing. Anthropogenic factors include
pollution (e.g. oil, contaminants, particles), physical disturbance, elevated nutrient levels and effects from
fisheries.
A number of different methods are being used to investigate flora and fauna on hard substrate according to
the survey aim and the type of biotope surveyed. To allow environmental authorities and others to make use
of this knowledge, it is essential that surveys are intercomparable in time and space, as well as between
operators, and that the data are of a high quality. This International Standard is based on a limited selection of
methods that allow precise documentation, that are replicable and which have been tested over many years.
In choosing methods for this standard, semi-quantitative and quantitative techniques have been emphasized,
such that species and quantities can be related to a known area of sea floor.
For the purposes of this International Standard, hard substrate is defined as bedrock, stable rocks and fixed
marine constructions (e.g. pipelines and quays). The main focus is on biological surveys based on species
that can be recorded in the field (i.e. that are visible to the naked eye).
The guidelines are applicable to seagrass communities and their epiflora and epifauna. They can also be used
for surveys of stable substrates comprising loose pebbles/boulders, stone blocks, coarse gravel and other
loose material as well as bedrock covered with loose sediment, but in general, such substrates require
specially adapted techniques. Additional methods are usually required for surveys in depths greater than
approximately 30 m.
For sediment sampling in marine areas, refer to ISO 5667-19. For surveys of sublittoral soft-bottom fauna, see
ISO 16665.
INTERNATIONAL STANDARD ISO 19493:2007(E)
Water quality — Guidance on marine biological surveys of hard-
substrate communities
1 Scope
This International Standard provides guidance for marine biological surveys of supralittoral, eulittoral and
sublittoral hard substrate for environmental impact assessment and monitoring in coastal areas.
This International Standard comprises
⎯ development of the sampling programme,
⎯ survey methods,
⎯ species identification, and
⎯ storage of data and collected material.
This International 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 International
Standard, but such techniques can be used as a supplement to obtain information on small-sized species or
those that live hidden.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
area of influence
area influenced or expected to be influenced, based on the available information
2.2
biotope
area of uniform environmental conditions (habitat) and its characteristic assemblage of plant and/or animal
species
EXAMPLE Laminaria hyperborea community (cuvie or tangleweed), knotted wrack community, blue mussel belt.
2.3
macroscopic organisms
algae and animals that are visible without magnification equipment (W 1 mm) and which can be recorded in
the field
NOTE Certain macroscopic organisms can require microscopic inspection for identification. For microscopy of
collected material, the lower size limit is set to 1 mm.
ISO 19493:2007(E)
2.4
hard substrate
substrate consisting of bedrock, larger rocks/stones or fixed marine constructions such as wharfs, quays and
pipelines
NOTE For the purpose of this International Standard, hard substrate can also include other substrates that are not
likely to be moved or turned over during a reasonable time period so that perennial species communities are likely to
develop (e.g. pebbles and stones in sheltered environments).
2.5
hard substrate flora and fauna
attached algae and animals, together with relatively stationary animals living on or in close association with
hard substrate
EXAMPLE Attached: kelp, seaweeds, sponges, bryozoans, corals, mussels, barnacles, ascidians. Relatively
stationary: snails, sea-urchins, crabs.
2.6
supralittoral zone
zone above the eulittoral zone, which is reached by spray water
NOTE Its upper limit is normally determined by the upper limit of Verrucaria (black lichen belt), blue-green algae
(usually Calot
