These photographs show a small boat on a beach at low tide in Brest harbor, whose hull is affected by biofouling.

Summary

Description
Français :

Ces photographies représentent un petit bateau sur une plage à marée basse en rade Brest, dont la coque est atteinte de biofouling. Le biofouling est un phénomène apparaissant en milieu aqueux ou humide à la surface d’un objet immergé dans ce milieu de manière fréquente ou permanente. Ce phénomène s’explique par le développement de micro et/ou de macro-organismes à la surface de l’objet immergé. Dans l’environnement marin, tous les substrats, vivants ou morts, naturels ou artificiels, sont rapidement colonisés par ces organismes présents naturellement dans l’eau de mer (végétaux ou animaux). Les types de matériaux sur lesquels se développent ces organismes sont très étendus. Dans la navigation maritime, ce phénomène est un réel problème, car il provoque un ralentissement du moyen de transport et une dégradation du matériau.

These photographs show a small boat on a beach at low tide in Brest harbor, whose hull is affected by biofouling. Biofouling is a phenomenon that appears in an aqueous or humid environment on the surface of an object immersed in this environment frequently or permanently. This phenomenon is explained by the development of micro and/or macro-organisms on the surface of the immersed object. In the marine environment, all substrates, living or dead, natural or artificial, are quickly colonized by these organisms naturally present in seawater (plants or animals). The types of materials on which these organisms develop are very broad. In maritime navigation, this phenomenon is a real problem, because it causes a slowdown in the means of transport and a degradation of the material.
