16. Characterizing and reconstructing 500 years of climate in the Baltic sea Basin
Sammanfattning : Climate has always attracted considerable interest, and climate observations have been made in various ways for most of human history. Regional climate and how it varies is of particular interest, as it sets the scene for our everyday life. LÄS MER
17. Ocean Climate Variability over Recent Centuries Explored by Modelling the Baltic Sea
Sammanfattning : Natural variability and anthropogenic factors both contribute to changes in the ocean climate of the Baltic Sea. Observations over the past century indicate that changes in environmental settings and ocean climate have taken place, attracting considerable media attention and building public awareness of climate and environmental issues related to the Baltic Sea.

18. Modelling Microwave Backscattering from Sea Ice for Synthetic-Aperture Radar Applications
Sammanfattning : The spaceborne synthetic-aperture radar (SAR) is considered one of the key instruments for monitoring the ice cover in polar oceans and regional seas. This thesis is concerned with applications of electromagnetic scattering theory and SAR system theory for modelling the response of different types of sea ice in SAR imagery. LÄS MER
19. Hydrology and Bed Topography of the Greenland Ice Sheet : Last known surroundings
Sammanfattning : The increased temperatures in the Arctic accelerate the loss of land based ice stored in glaciers. The Greenland Ice Sheet is the largest ice mass in the Northern Hemisphere and holds ~10% of all the freshwater on Earth, equivalent to ~7 metres of global sea level rise. LÄS MER
20. Efficient commuter craft for urban waterborne public transportation
Sammanfattning : There has been a recent surge in interest in waterborne public transportation (WPT). Publictransport providers (PTP) are seeing its potential in complementing the existing transportnetwork and alleviating urban traffic congestion and pollution. But the adoption of WPTtoday is challenging due to a series of technical and implementation challenges. LÄS MER
