Projects Detail

Eurasian isotope transect

Minute amounts of drip water are trapped as fluid inclusions in stalagmites in caves. This water represents samples of palaeoprecipitation, contemporaneous with speleothem growth. Our project aims at measuring the isotopic composition of this palaeowater trapped in the course of the Holocene, i.e. the last 11,700 yrs. The data will be acquired from cave sites located along a 8,500 km-long longitudinal transect, following the direction of the moisture transport from the Atlantic seaboard of the Europe inland to eastern Siberia (Lake Baikal). If successful, this project will be a major step toward using stable water isotopes in this part of the world for quantitative palaeoclimate and palaeohydrological studies. The applicant’s group operates one of the very few analytical lines worldwide capable of measuring the isotopic composition of fluid-inclusion water.
