Última Contribution of climate variability to occurrences of anoxic crises 'malaigues' in the Thau lagoon (southern France) ArchiMer Harzallah, Ali; Chapelle, Annie. The Thau lagoon, located in southern France, suffers episodically in summer from anoxic crises known as 'malaigues'. Such crises mostly occur under warm conditions and low winds. In this paper we investigated effects of local weather conditions (air temperature, wind speed and precipitation over southern France), and two climate oscillations (the North Atlantic Oscillation and the El Ni (n) over tildeo Oscillation) on malaigue occurrences based on 33-year data series and dates when malaigues appeared. The study shows that the probability of occurrence of malaigues increases with increasing temperature and decreasing winds in August both mostly associated to the high phase of an index of North Atlantic Oscillation. Malaigues are found to be frequently... Tipo: Text Palavras-chave: Lagoon; Thau; Malaigues; Anoxic crises; Climate variability; Lagune; Thau; Malaïgue; Eutrophisation; Variabilité climatique.

Moyens de lutte, recommandations ArchiMer Hamon, Pierre-yves; Vercelli, Catherine; Pichot, Yves; Lagarde, Franck; Le Gall, Patrik; Oheix, Jocelyne. The Thau Lagoon, from time to time is the area of crisis locally called « malaïgues ». The characteristics of these « malaïgues » are the lack of oxygen interesting all the water column and the white color of the waters during the phenomena. The result of this anoxy is the death of cultivated molluscs. From 1969 to 2000 nine « malaïgues » have been observed. They occur during the Summer period but in different locations. The surface of the areas concerned are very different according the year. Different means of struggle have been tried and are described.

Relations entre les conditions physico-chimiques, la météorologie et les conditions d'apparition des crises dystrophiques ArchiMer Hamon, Pierre-yves; Vercelli, Catherine; Pichot, Yves; Lagarde, Franck; Le Gall, Patrik; Oheix, Jocelyne. In the first volume dystrophie crisis in the Thau lagoon since 1969 are described. In the second volume, meteorological parameters (temperature, wind, atmospheric pressure) are compared during the dystrophie crisis to show if either one or several parameters could explain the emergence of these phenomena . It seems that only a mathematical model could be able to give explanation. Tipo: Text Palavras-chave: Anoxie; Malaïgue; Météorologie; Lagune de Thau.
