11. Post-Glacial History of Sea-Level and Environmental Change in the Southern Baltic Sea
Sammanfattning : A new palaeoenvironmental record of the post-glacial history of the southern Baltic Sea (~14 ka to present) is presented. During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. LÄS MER
12. Glaciodynamics, Deglacial Landforms and Isostatic Uplift during the last Deglaciation of Norrbotten, Sweden
Sammanfattning : The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations.

13. Early Campanian mosasaurs (Reptilia; Mosasauridae) from the Kristianstad Basin, southern Sweden
Sammanfattning : Marine strata of latest early Campanian age (sensu germanico) in the Kristianstad Basin, Skåne (Scania), southern Sweden, have yielded a diverse mosasaur fauna comprising six to eight taxa, including Tylosaurus ivoensis, Clidastes propython, Hainosaurus minor n. sp., Halisaurus sternbergii, Platecarpus cf. somenensis, Platecarpus? sp.

14. Predictive Modelling of Heavy Metals in Urban Lakes
Sammanfattning : Heavy metals are well-known environmental pollutants. In this thesis predictive models for heavy metals in urban lakes are discussed and new models presented. The base of predictive modelling is empirical data from field investigations of many ecosystems covering a wide range of ecosystem characteristics. LÄS MER
15. Predictive Models and Eutrophication Effects of Fish Farms
Sammanfattning : Aquaculture has become one of the fastest growing food industries in the world. Like many other industries, aquaculture, and especially fish farms may cause negative effects on the environment, such as eutrophication, which is recognised as a major threat to aquatic ecosystems.
