Abstrakt

We propose a new shore-level displacement curve for southern Lolland and the Femern Belt in south-eastern Denmark based on 94 new and four published radiocarbon ages of organic material and shells of marine molluscs. Mires existed in the deeper parts of the Femern Belt during the Early Holocene, and a large lake formed as the water level gradually rose. The lake phase was followed first by a brackish-water phase from c. 8500 cal a bp and by a marine phase after c. 7800 cal a bp when the relative sea level was ~8 m lower than at present. Over the past 6500 years the sea level has gradually risen by ~2 m and reached its highest level in recent times. There are no indications of a higher than present sea level in the area and no indications of 1–2 m sea-level oscillations as reported from other parts of the region. The relative sea-level curve for southern Lolland differs from relative sea-level curves from northern parts of Denmark, which are more influenced by glacio-isostatic uplift. Southern Lolland has been uplifted by 4–5 m over the last 8000 years, whereas the Limfjord region in northern Denmark has been uplifted by around 12 m during the same period.
