    Des que I'any 1983 es va detectar una situacio meromictica a l'Estany des Cibollar, s'han succeit diversos estudis que han perrnes coneixer el seu funcionament. Aqui es presenta breument la inforrnacio que en I'actualitat es te d'aquesta Ilacuna costanera, de la seva dinarnica i de les comunitats planctoniques que s'hi desenvolupen.

    La meromixi ectoqenica de l'Estany des Cibollar determina les seves principals caracteristiques.

    L'estratificacio de la columna d'aigua dificulta la mescla vertical provocant una anoxia permanent en el monimolimnion, una inversio terrnica durant I'hivern i un maxim d'oxigen dissolt en el metalimnion

    Since 1983, when a meromictic situation was detected at the "Estany des Cibollar", several studies have been carried out in order to understand its dynamics. The information available on its functioning and planktonic communities is briefly reviewed.

    The ectogenic meromixis present in the "Estany des Cibollar" conditions the main characteristics of the lagoon. Water column stratification interferes with vertical mixing provoking permanent anoxia in the monimolimnion there is a community of photometalimnion. An outstanding component of this community is the mixo and metalimnion. An outstanding component of this community is the bluegreen Synechococcus, with maximum densities in the metalimnion. The zooplanktonic community is dominated by copepods and rotifers, and it encompasses the myxo and metalimnion
