Qualité de l’eau — Lignes directrices pour les études biologiques marines des peuplements du substrat dur
| Published By | Publication Date | Number of Pages |
| ISO | 2007-06 | 32 |
L'ISO 19493:2007 fournit des lignes directrices pour conduire des études biologiques marines du substrat dur supralittoral, eulittoral et sublittoral afin d'évaluer et de surveiller l'impact environnemental dans les zones côtières. Elle couvre le développement du programme d'échantillonnage, les méthodes d'étude, l'identification des espèces, le stockage des données et la conservation du matériel collecté.
L'ISO 19493:2007 spécifie les exigences minimales relatives à la surveillance de l'environnement.
Les méthodes se limitent aux études et aux techniques d'enregistrement semi-quantitatives et quantitatives qui engendrent une destruction mineure de la faune et de la flore. Dans la pratique, elles s'appliquent à l'enregistrement direct sur le terrain et à la photographie. L'ISO 19493:2007 ne couvre ni les prélèvements d'organismes par raclage, ni l'utilisation d'un échantillonneur aspirant ou analogue.
