Tree-rings and climate - Standardization, proxy-development, and Fennoscandian summer temperature history
(2014-05-15)Instrumental meteorological observation are too short for trying to estimate climate change and variability on multi-decadal and centennial time-scales, and when trying to evaluate the response of the climate system to ... -
Predicting Spatial and Stratigraphic Quick-clay Distribution in SW Sweden
(2014-05-12)Clay sediments are associated with a wide variety of engineering problems, of which landslides, together with settlement, are the most investigated due to the large associated costs. Quick-clay deposits, which if disturbed ... -
Late Holocene spatiotemporal hydroclimatic variability over Fennoscandia inferred from tree-rings
(2014-01-27)There is a broad scientific consensus that the global climate is changing, and that human activity is a significant factor contributing to the change. The response of the hydrological cycle to the warming is far reaching, ... -
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 ... -
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 ... -
Precambrian Crustal Evolution of the Rehoboth Province, Southern Africa
(2013-05-08)This thesis uses U-Pb, Sm-Nd Lu-Hf, Ar-Ar and Oxygen isotope data on well-documented rock samples, to investigate crustal evolution of the Precambrian Rehoboth Province of Southern Africa. This province is defined by its ... -
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 ... -
Observed and simulated changes in extreme precipitation and cold surges in China: 1961–2005
(2013-02-01)In the present work, precipitation and temperature related climate extremes are examined, with a focus on Mainland China. The objectives of this study are a) to identify targeted climate extremes and their changes during ... -
Phosphorus recycling in brackish and marine environments - Sediment investigations in situ in the Baltic Sea and the By Fjord
(2012-11-29)The phosphorus load to the oceans from land started to increase since around 1950 when man started to mine phosphorus-mineral from phosphorus-rich soils and bedrock. The increased use of phosphorus fertilizers in agriculture ... -
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 ... -
Cold-climate landforms on Mars and Earth-analogues in Svalbard
(2012-09-14)Periglacial landforms on Earth reflect cold-climate conditions and are intimately related to processes due to the presence of ground ice and perennially frozen ground, permafrost. The overall objective of this thesis is ... -
Simulated and observed change of precipitation and temperature in Europe with focus on the Greater Baltic Area
(2012-05-24)The regional climate of the Greater Baltic Area is complex and varies at a multitude of scales in space and time. This thesis contributes to increased understanding of climate change and climate variability in this area ... -
Forest and land use mitigation and adaptation in Sri Lanka – Aspects in the light of international climate change policies
(2012-03-05)As a developing island nation, Sri Lanka is vulnerable to the possible impacts of climate change. The land use and forestry sector accounts for a large part of Sri Lanka’s greenhouse gas emissions and can play a major ... -
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 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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
