Накратко на български
Температурните промени в Западна Европа по време на последния ледников период се анализират чрез черупки от наземни охлякани в седименти. Това помага да се определят точните стойности и времеви рамки на резките климатични скокове в континенталната част на Европа.

Цел на проекта
The abrupt climate changes are presently among the more exciting topics in paleoclimatology. Mostly recorded during the last glacial period between 70 and 20 kyr BP, they have lasted only a few centuries, set up in 10 to 50 years, implying atmospheric temperature changes of about 10°C over Greenland, and several Celsius degrees of the summer SSTs in the North Atlantic Ocean.Up to now, on the European continent, no quantification of the temperature changes associated with these abrupt climatic changes has been ever performed. Indeed, sometimes involved to explain quick excursions in signals provided by pollen records, their first detailed characterisation in continental sediment as only recently be demonstrated in the loess sequence of Nussloch (Germany), through grain size analysis and terrestrial molluscs records.Loess are the most appropriate material as they were mainly deposited during the last glacial period dominated by a stronger atmospheric circulation, and huge dust transports coming from large dry deflation source areas, dues to the sea level drop and the decrease of the hydrological cycle. The aim of this proposal is thus to quantify climatic changes associated with these abrupt changes in continental domain, and to define the associated chronological framework. Up to now, terrestrial mollusc shells are the best-represented biological proxy in loess, and thus, the only one able to support any quantitative climatic parameters reconstructions.Nevertheless, the majority of the quantitative methods previously developed on them are presently suffering calibration problems avoiding their regular use. We has so decided to apply the newly developed amino acids paleothermometry method to quantify temperature changes along the last glacial period recorded in Nussloch. Numerous ages will also be provided through luminescence analysis to detail the chronological framework of the reconstructed temperature variations, and especially during the last Pleniglacial.
