A 36 ka environmental record in the southern tropics : Lake Tritrivakely (Madgascar) (Un enregistrement de l'environnement depuis 36 ka en zone tropicale sud : le lac Tritrivakely (Madagascar)).

Abstract : The upper 13 m of a 40 m-long sedimentary profile core taken in a crater lake on the Malagasy Plateau reveals 36,000 yrs of hydroclimatic evolution. A shallow lake occupies the core site from ≃35 to ≃19 ka BP under climatic conditions cooler than today. The water table is very low and biological productivity extremely reduced during the Last Glacial Maximum. A large warming was initiated at ≃14.5 ka BP. The modern bog establishes about 4 ka ago
