Description
After the fish mortality through an anoxia, which occured during the summer of 1982 in the bay of Vilaine, the oxygen consumption of the sediment was investigated during spring and summer. It was found moderately important, submitted to limited evolutions along time and on different zones. A significant correlation with the organic carbon content of sediment could not be established. The oxygen consumption of the bottom waters was approached. In the bay of Vilaine as a whole, it was found more important than the sediment consumption. It could vary in a wide range, till leading to pronounced hypoxias, especially during phytoplankton. (Not controlled OCR)
