Proterozoic to Quaternary Events of Fracture Mineralisation and Oxidation in SE Sweden
(2008-11-18)Fracture minerals and altered wall rock have been analysed to reveal the low-temperature evolution, especially regarding redox conditions, of the Simpevarp area, SE Sweden. This area is one of the two areas in Sweden ... -
Fluid Migration and Brittle Tectonothermal Evolution in the Central Fennoscandian Shield - Recorded by Fracture Minerals and Wall Rock Alteration
(2009-04-16)The Forsmark area in central Sweden has been investigated as a potential geological host for a final repository of spent nuclear fuel by the Swedish Nuclear Fuel and Waste Management Company (SKB). High quality drill core ... -
Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes
(2009-05-06)This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamics and finally sea ... -
Regional and local surface ozone variations in relation to meteorological conditions in Sweden
(2009-05-07)Air quality is strongly dependent on meteorological conditions. Atmospheric circulation encapsulates general information about local meteorological variables to some extent, and can serve as an explanatory variable for ... -
Characterizing and reconstructing 500 years of climate in the Baltic sea Basin
(2009-05-13)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 ... -
Ocean Climate Variability over Recent Centuries Explored by Modelling the Baltic Sea
(2009-09-03)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 ... -
The Tropospheric Aerosol - Measurements and Modelling. Case studies in Tanzania and Southeast Asia and development of models for size resolved aerosol simulations on the regional scale.
(2009-10-01)The tropospheric aerosol is a complex constituent of the atmosphere that has impacts on health and the climate. This thesis presents five different studies from Tanzania, Southeast Asia and Europe dealing with urban ... -
Crystallization and Differentiation Processes in the Thin Layered Alkali Gabbroic Intrusions of the Ulvö Gabbro Complex, Central Sweden
(2009-10-22)Fractional crystallization of magma is a commonly invoked mechanism for chemical differentiation in systems that range from volcanoes to entire planets. However, the processes that control separation of crystals and liquids ... -
Land Use in Climate Policy - Forest Based Options at Local Level with Cases from India
(2009-11-06)With India’s large population, an increased pressure on forest and agricultural land indicate a growing demand for environmental services that is sustainable for the future. Fertile agricultural land is limited and with ... -
Proterozoic crustal evolution in southcentral Fennoscandia
(2010-01-13)The Transscandinavian Igneous Belt (TIB) and the Eastern Segment of the Southwest Scandinavian Domain reflect advanced stages of continental growth within the Fennoscandian Shield. The relationship between the two units ... -
Winter Road Conditions and Traffic Accidents in Sweden and UK - Present and Future Climate Scenarios
(2010-02-04)This thesis investigates the distribution of slippery roads in Sweden and the UK for the present climate and how this may be affected by climate change for the rest of the century. It also addresses future scenarios for ... -
Changes of evapotranspiration and water cycle in China during the past decades
(2010-02-09)Evapotranspiration is the second largest quantity in the water cycle and an important indicator for climate changes. Accurate estimations and better understanding of evapotranspiration are required in hydrologic studies ... -
The Baltic Sea marine system - human impact and natural variations
(2010-09-07)The environmental state of the Baltic Sea system is influenced by both natural and anthropogenic factors. Water exchange with the adjacent ocean and within the system depend on large-scale atmospheric circulation and ... -
Pressure, temperature and time constraints on tectonic models for southwestern Sweden
(2010-11-12)In this work, a number of key localities have been investigated in detail in order to provide precise constraints on models for the tectonic evolution of southern Sweden. The new data presented in this thesis show that ... -
Urban Climate and Air Pollution in Ouagadougou, Burkina Faso
(2011-05-05)ABSTRACT Africa has recently been singled out by UN Habitat as the fastest urbanizing continent in the world. The most extreme case was found in the Sahelian city of Ouagadougou, Burkina Faso, where the population is ... -
The Mesoproterozoic Hallandian event - a region-scale orogenic event in the Fennoscandian Shield
(2011-05-19)The Sveconorwegian Province occupies the southwestern part of the Fennoscandian Shield. The easternmost tectonic unit of the Province is the 1710-1660 Ma parautochthonous Eastern Segment, which bears the imprint of at least ... -
The Carbon Dioxide System in the Baltic Sea Surface Waters
(2011-05-26)The concentration of carbon dioxide (CO2) in the atmosphere is steadily increasing because of human activities such as fossil fuel burning. To understand how this is affecting the planet, several pieces of knowledge of the ... -
Instruments for reaching climate objectives. Focusing on the time aspects of bioenergy and allocation rules in the European Union's Emission Trading System
(2011-09-29)The Europeans Union’s (EU’s) climate and energy strategy aims at reducing the emissions of greenhouse gases (GHG) by 20 % (compared to 1990) and to increase the share of renewable energy to 20 % by the year 2020. Increased ... -
