The project C3 investigates limnological archives on the southern Iberian Peninsula to unravel past environmental and climatic conditions of the late Quaternary.
The lacustrine deposits of the Laguna de Medina in southern Spain, the second largest inland salt lake of Andalusia situated in Triassic gypsum karst, have been investigated. Two sediment cores with a total length of 25,66 m were drilled from a platform. Preliminary results of the Laguna de Medina record cover a more or less continuous record of sediments and, hence, a tool to unravel past conditions. The lake sediments demonstrate high variations of water depth and salinity. Moreover, the lake shows a trend of perennial conditions in earlier times to ephemeral conditions, closely linked to climate and associated changes. Our preliminary results show a high resolution signal of probably the last 30 000 years.
The Laguna Salada next to the city Campillos is investigated by researching a 2m long sediment core via multi-proxy analysis, which do show variability concerning past environmental conditions on a local scale. The age models shows the core is about 2000 years old , but a comparison to other archives within close distance is difficult, which seems to be due the small size and the low water column of the lake, which constitutes furthermore a problem for the preservation of pollen.
In comparison with other archives, these studies will lead to a much better understanding of the relation between climate and human migration on the Iberian Peninsula because of our multi-proxy approach and a close interfingering with archaeologists working in the nearest archaeological sites.
