dc.description.abstract | [EN] The karstic Lake Montcortès sedimentary sequence spanning the last 1548. yr constitutes the first continuous, high-resolution, multi-proxy varved record in northern Spain. Sediments consist of biogenic varves composed of calcite, organic matter and detrital laminae and turbidite layers. Calcite layer thickness and internal sub-layering indicate changes in water temperature and seasonality whereas the frequency of detrital layers reflects rainfall variability. Higher temperatures occurred in Lake Montcortès in AD 555-738, 825-875, 1010-1322 and 1874-present. Lower temperatures and prolonged winter conditions were recorded in AD 1446-1598, 1663-1711 and 1759-1819. Extreme and multiple precipitation events dominated in AD 571-593, 848-922, 987-1086, 1168-1196, 1217-1249, 1444-1457, 1728-1741 and 1840-1875, indicating complex hydrological variability in NE Spain since AD 463. The sedimentary record of Lake Montcortès reveals a short-term relation between rainfall variability and the detrital influx, pronounced during extended periods of reduced anthropogenic influences. In pre-industrial times, during warm climate episodes, population and land use increased in the area. After the onset of the industrialization, the relationship between climate and human activities decoupled and population dynamics and landscape modifications were therefore mostly determined by socio-economic factors. © 2012 University of Washington. | - |
dc.description.sponsorship | Financial support for this research was provided by the Spanish Inter‐Ministry of Science and Technology (CICYT), through the projects GLOBALKARST (REN2003-09130-C02-02), and GRACCIE (CSD2007-00067). Additional funding was provided by the Aragonese Regional Government-CAJA INMACULADA and a bilateral DAAD‐CICYT project, which partially funded microfacies analysis at GFZ (Potsdam) through a travel grant. Juan Pablo Corella was supported by a PhD contract with CONAI + D (Aragonese Scientific Council for Research and Development), Mario Morellón is supported by a postdoctoral fellowship funded by the Spanish Ministry of Education and Science and Clara Mangili hold postdoctoral a fellowship at Lamont–Doherty Earth Observatory, respectively. We thank Arsenio Muñoz for his comments and suggestions in this paper. We are also indebted to the GFZ and IPE‐CSIC laboratory staffs for their collaboration in this research. The comments of J.C. Knox, Santiago Giralt and of an anonymous reviewer greatly improved a previous version of the manuscript. | - |
