1. Diatom stratigraphy and evidence of Holocene environmental changes in selected lake basins in the Antarctic and South Georgia
Sammanfattning : .... LÄS MER
2. Tracing environmental change and human impact as recorded in sediments from coastal areas of the northwestern Baltic Proper
Sammanfattning : The eutrophication of the Baltic Sea due to increased anthropogenic nutrient loads during the 20th century is well documented and studied. However, in the Baltic Sea drainage area, humans have affected the environment longer than the environmental monitoring can provide data for. LÄS MER
3. Holocene environmental changes recorded by diatom stratigraphy in the southern Baltic Sea
Sammanfattning : Sediment cores from the southern Baltic Sea and the Oder River estuary are analysed for their siliceous microfossil assemblages and organic carbon content. Long piston cores from the Bornholm and Gotland Basins provide data on the long-term Holocene history of the Baltic proper and serve as a natural background when evaluating the most recent environmental changes recorded in the short gravity cores.

4. Early Holocene shore displacement in eastern Svealand, Sweden, based on diatom stratigraphy, radiocarbon chronology and geochemical parameters
Sammanfattning : .... LÄS MER
5. Combining limnology and paleolimnology : a refined understanding of environmental sediment signal formation in a varved lake
Sammanfattning : Paleoclimatic archives, such as lake sediments, extend our understanding of terrestrial and aquatic ecosystem dynamics in relation to climate variability beyond the period covered by instrumental data. In this context, annually laminated (i.e. LÄS MER
