Abstract
The Danish landscape is characterised by low relief and consequently the risk of soil erosion is low compared to many central and southern European countries with more variable terrain (European Environment Agency 2000; Van der Knijff et al. 2000). However, even in countries with less intensive erosion, water-induced soil erosion is recognised as an increasingly important environmental issue due to its role in the transport of nutrients, pesticides and other contaminants to rivers, lakes and coastal waters (e.g. Stone 2000).
Highlights
The Danish landscape is characterised by low relief and the risk of soil erosion is low compared to many central and southern European countries with more variable terrain (European Environment Agency 2000; Van der Knijff et al 2000)
Numerous archaeological excavations have been undertaken near Gudme Sø, and the Geological Survey of Denmark and Greenland has carried out analyses of sediments from the lake to provide a continuous picture of landscape changes
Chronology The 14C dates from the Gudme Sø sediment core are based on bulk sediment samples and may overestimate their actual ages due to the hard-water effect (Björck & Wohlfarth 2001)
Summary
The Danish landscape is characterised by low relief and the risk of soil erosion is low compared to many central and southern European countries with more variable terrain (European Environment Agency 2000; Van der Knijff et al 2000). Lake and fjord sediment archives are especially useful because they can provide continuous and undisturbed sediment successions that can be analysed at high temporal resolution These sediment records can be examined using a variety of approaches that include sedimentological, geochemical and biological analyses and generate important insight into baseline states, trajectories and responses to forcing mechanisms over long timescales, which would otherwise be difficult to obtain. Sediment accumulation rates of minerogenic matter and pollen analysis are here used to explore the erosional response to changes in land-use. It has no major natural inlets or outlets. Sediment accumulation rates of minerogenic matter (SAR-min in mg/cm per year) were calculated and used as proxies of soil erosion from the catchment area to the lake The record of colonies of the green algae Pediastrum sp. is used as proxy evidence for in-lake productivity (Bradshaw et al 2005)
