1. Estimating the Air-Water Gas Transfer Velocity during Low Wind Conditions
Abstract : The abundances of atmospheric carbon dioxide, CO2, and methane, CH4, are increasing. These increases affect e.g., the global carbon cycle and the climate both regionally and globally. READ MORE

2. Sources of dioxins and other POPs to the marine environment : Identification and apportionment using pattern analysis and receptor modeling
Abstract : In the studies underlying this thesis, various source tracing techniques were applied to environmental samples from the Baltic region. Comprehensive sampling and analysis of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in surface sediments in Swedish coastal and offshore areas resulted in a unique data set for this region.

3. Land use effects on greenhouse gas emissions from boreal inland waters
Abstract : Anthropogenic activities perturb the global carbon and nitrogen cycle with large implications for the earth’s climate. Land use activities deliver excess carbon and nitrogen to aquatic ecosystems. In the boreal biome, this is mainly due to forestry and atmospheric deposition. READ MORE

4. Seagrasses in warming oceans : physiological and biogeochemical responses
Abstract : The exponential increase of atmospheric greenhouse gas concentrations over the past 50 years has caused a rise in the global average temperature by more than 1ºC above pre-industrial levels. Ninety-three percent of this heat energy has been absorbed and stored by the oceans, increasing their temperatures, particularly in surface waters. READ MORE

5. Enantiospecific Analysis and Environmental Behavior of Chiral Persistent Organic Pollutants (POPs)
Abstract : Many persistent organic pollutants (POPs) are chiral. These pollutants are generally released into the environment as racemates, but frequently undergo alterations in enantiomeric composition as soon as they are subjected to life chemistry processes. READ MORE
