Here you can see different pictures and a video of our fieldwork in Sierra Nevada. With these images we would like to show the different kinds of sampling campaigns that were carried out. As most of the lakes and borreguiles (local term for wet lands) are at high altitude (around 3000 masl), and access is not possible with vehicles, most of the samples were taken with a manual Livingstone piston corer. A drill-corer was only used in Laguna Seca.

SIERRA NEVADA AREA

It is located in the southern sector of the Iberian Peninsula at about 37ºN. There are around 50 alpine lakes and wetlands of glacial origin, most of them situated between 2800 and 3100 masl. In addition, there is a low-altitude large peat bog in the western side of Sierra Nevada, El Padul peat bog. So far, the oldest sedimentary record of the high alpine lakes is around 12 cal ky BP. However, the El Padul record extends to 1 Ma. Although we will take into account all the paleoenvironmental studies in the area - including those in Laguna de Rio Seco, Laguna de la Mula, Laguna de la Mosca and Laguna Seca- the NAOSIPUK project is focused on the records from Borreguiles de la Virgen (2945 masl) and El Padul peat bog (710 masl).

We have focused on southern Iberian Peninsula, a very sensitive area to climate change, as most parts of the Mediterranean region. The global change has become a serious environmental problem there, more specifically in different areas in Sierra Nevada, a National and Natural Park with a large number of endemic species. It is the highest mountain range in southwestern Europe with more than 3000 masl. Our aim is to identify the response of the ecosystems in the past to learn about their possible future evolution. Our paleoenvironmental research in this area started in 2006 and, at present, eight lakes and wet lands have been sampled.
