1. 21. Long-term beach and dune evolution : Development and application of the CS-model

   Författare :Caroline Hallin; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coastal processes; sediment transport; numerical modelling; Ängelholm Beach; Kennemer Dunes;

   Sammanfattning : Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. LÄS MER

3. 22. Late Weichselian and early Holocene shore displacement in the central Baltic, based on stratigraphical and morphological records from eastern Småland and Gotland, Sweden

   Författare :Nils-Olof Svensson; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollen; Paleontologi; Shore displacement; Land uplift; Paleobotanic;

   Sammanfattning : The glacial unloading and resulting isostatic land uplift have together with hydro-isostasy, eustatic rise of sea-level and geoidal changes, ruled the shore displacement of Fennoscandia. Within the Baltic basin, periods of damming and shifts of outlet further complicated the shore displacement during the period studied, c. 12,200-8400 BP. LÄS MER

4. 23. Computational Ice Sheet Dynamics : Error control and efficiency

   Författare :Josefin Ahlkrona; Per Lötstedt; Jesse Johnson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice sheet modelling; stokes equations; shallow ice approximation; finite element method; perturbation expansions; non-newtonian fluids; free surface flow; Scientific Computing; Beräkningsvetenskap;

   Sammanfattning : Ice sheets, such as the Greenland Ice Sheet or Antarctic Ice Sheet, have a fundamental impact on landscape formation, the global climate system, and on sea level rise. The slow, creeping flow of ice can be represented by a non-linear version of the Stokes equations, which treat ice as a non-Newtonian, viscous fluid. LÄS MER

5. 24. Arctic Climate and Water Change : Information Relevance for Assessment and Adaptation

   Författare :Arvid Bring; Georgia Destouni; Richard Lammers; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Monitoring; Arctic; Climate Change; Adaptatation; Physical Geography; naturgeografi;

   Sammanfattning : The Arctic is subject to growing economic and political interest. Meanwhile, its water and climate systems are in rapid transformation. Relevant and accessible information about water and climate is therefore vital to detect, understand and adapt to the changes. LÄS MER

7. 25. The Baltic Sea from the present to future : microbial carbon & nutrient cycling in a changing climate

   Sammanfattning : Climate Change is caused by the accelerated increase of anthropogenic greenhousegas emissions to the atmosphere and affects all ecosystems on our planet. A resultof higher CO2 uptake by the oceans as well as an increase of heat trapped in theatmosphere leads to, for example acidification, stratification, sea-level rise, oxygenloss, and temperature increase of the earth’s waterbodies.
