Rheological response to tectonic and volcanic deformation in Iceland
(2016-05-06)
Iceland is one of the few places in the world where a Mid-Oceanic Ridge (MOR) is exposed on land, and this gives good opportunity to study geodynamic processes. Spreading of Mid-Atlantic Ocean Ridge (MAR) segments in Iceland ...
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 ...
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 ...
Rainfall variability, soils and land use changes in the Ethiopian highlands
(2013-09-16)
Most farmers in the Ethiopian highlands are dependent on rain-fed agriculture. The indigenous cereal tef is the most important crop for the farmers in the highlands. The central highland is an environmentally fragile area ...
Modelling of the daytime and night-time urban thermal environment
(2016-03-11)
The world’s urban population is expected to increase over the coming decades. To maintain and improve the health and well-being of urban citizens, it is important to increase our knowledge and develop methods for evaluating ...
Nitrous Oxide Production in Agricultural Soil – Linking Biogeochemical Pathways and Drivers
(2018-05-09)
Nitrous oxide (N2O) is a long-lasting and potent greenhouse gas responsible for depletion of stratospheric ozone. As the atmospheric N2O concentration reaches all-time highs, emission variability in space and time still ...
Studies of the Arctic Ocean sea ice cover and hydrothermal heat fluxes
(2012-10-26)
Since reliable ice extent estimates from satellite data became available in 1979 the Arctic sea ice cover has followed a declining long term trend. Over the last decade the decline has accelerated with record low sea ice ...
Modelling the Dissolved Inorganic Carbon System in the Baltic Sea
(2013-10-04)
Oceans are capable of storing part of the emitted anthropogenic carbon dioxide (CO2) due to the formation of carbonic acid and subsequent dissociation. CO2 is also assimilated by biota and the inorganic carbon system is ...
MODEL STUDIES OF FISH EGG AND LARVAL TRANSPORT IN THE KATTEGAT AND THE NORTH ATLANTIC
(2013-03-06)
For the early life stages of fish, the dispersal and retention are important factors regarding present and future survivorship, growth and reproduction. The main objective of this thesis is to analyse fish egg and larval ...
