16. Diatom stratigraphy and evidence of Holocene environmental changes in selected lake basins in the Antarctic and South Georgia
Sammanfattning : .... LÄS MER
17. Holocene Environmental Change of Southern Öland, Sweden
Sammanfattning : This thesis describes Holocene environmental change in Ottenby, southern Öland,Sweden. Analyses of pollen sequences collected distally in the Littorina ridge and in fentroughs between lower laying beach ridges show the vegetation history during twoperiods, the first around 8000 BP and the second from 0/500 AD to about present time.

18. Holocene Climate in Central and Southern Sweden : Quantitative Reconstructions from Fossil Data
Sammanfattning : In quantitative palaeoecology modern species-environmental relationships can be statistically modelled, and recent development has made the calibration models more statistically robust. These models are used to transform fossil assemblages to quantitative estimates of past environmental conditions. LÄS MER
19. Influence of solar activity and environment on 10Be in recent natural archives
Sammanfattning : Understanding the link between the Sun and climate is vital in the current incidence of global climate change, and 10Be in natural archives constitutes an excellent tracer for this purpose. As cosmic rays enter the atmosphere, cosmogenic isotopes like 10Be and 14C are formed. LÄS MER
20. Event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden
Sammanfattning : This thesis outlines an event stratigraphy for the Last Glacial-Holocene transition in eastern middle Sweden. Events are short-lived occurrences that have left traces in the geological record and which, therefore, may be used for correlation and inter-regional comparisons. LÄS MER
