| Popis: |
Investigations on orgnaic carbon in sediments of Maar lakes reveal a relationship to paleotemperatures as reconstructed from Camp Century ice cores. Of great influence are also anthropogenic activities in the catchment area. Clearing of forest, agriculture and related settlement are related to increased soil erosion. These periods are characterised by high amounts of minerogenic deposition and increased absolute orgnaic carbon accumulation but lower organic carbon weight percentages. A microscopic examination of sediment thin sections provides data of mineral- and diatom assemblages, varve counts and enables to estimate sedimentation- and accumulation rates. Based on this information it seems to be possible to separate climatic and anthropogenic reasons for orgnaic carbon contents in Lake Schalkenmehrener Maar. |
