DescriptionAlgal bloom banner Inflorescence.jpg |
Français : Inflorescence planctonique. Ce sont a priori des cyanophycées (algue bleue). Dans ce cas, quelques heures (ici une quinzaine d'heure) après le début de l'épisode, les taches bleues se sont étendues.
Lieu : quai du Vault à Lille, non loin du centre ville (France), après une longue période pluvieuse (non caniculaire, et même sous les moyennes saisonnières, mais avec des nuits inhabituellement douces). Le canal proche (Deûle) est également couvert d’une couche de plancton vert sur de vastes surfaces (centaines de mètres carrés), mais beaucoup moins épaisse. Les échantillons dégagent une forte odeur d'algue (type spiruline). |
