16. Setting the Holocene clock using varved lake sediments in Sweden
Abstract : The aim of this thesis was to study annually laminated (varved) Holocene lake sediment in Sweden, their formation and their potential as chronological and palaeoecological archives. Five lakes with continuous Holocene varved lake sediment sequences in northern (Västerbotten) and west central Sweden (Värmland) were investigated. READ MORE

17. Model analysis of ocean carbon storage and transport across climate states
Abstract : The ocean carbon cycle plays a fundamental role in the Earth’s climate system, on decadal to multi-millennial timescales. Of the carbon held in the ocean, the atmosphere, and the terrestrial biosphere combined, more than 90% resides in the ocean. Carbon enters the surface ocean through air-sea gas exchange and from terrestrial sources. READ MORE

18. Cryogenic soil processes in a changing climate
Abstract : A considerable part of the global pool of terrestrial carbon is stored in high latitude soils. In these soils, repeated cycles of freezing and thawing creates soil motion (cryoturbation) that in combination with other cryogenic disturbance processes may play a profound role in controlling the carbon balance of the arctic soil.

19. Magnetic properties of magnetosomal greigite and factors influencing its occurrence and preservation in Baltic Sea Littorina sediments
Abstract : The Baltic Sea is one of the world’s largest brackish water environments and is today suffering from, for example, eutrophication, spreading hypoxia, accumulations of contaminants and invasive organisms. These problems exist due to a combination of natural features that makes the Baltic Sea a sensitive ecosystem (such as long water residence time, limited water exchange, large catchment area), and anthropogenic pressures on land, (such as agriculture and land-use changes, large human populations and industries) and in the sea (such as transport, fishing and bottom-trawling).

20. Electronic Labyrinths : An Archaeology of Videographic Cinema
Abstract : This study scans six decades of film history in search for video images, the imaginaries within which they are framed, and (taking cues from the archaeological methods of Friedrich Kittler and Michel Foucault) their technical, historical, and institutional conditions of existence. The British experimental science fiction film Anti-Clock (Jane Arden and Jack Bond, 1979) revolves around a video device with the capacity to confront subjects with their own repressed memory images.
