16. A large-eddy simulation perspective on Arctic airmass transformation and low-level cloud evolution
Sammanfattning : The Arctic is currently warming faster than other regions of the Earth. Many processes and feedbacks contribute to the enhanced warming. Among these are the radiative effects of clouds. LÄS MER
17. Tracing environmental change and human impact as recorded in sediments from coastal areas of the northwestern Baltic Proper
Sammanfattning : The eutrophication of the Baltic Sea due to increased anthropogenic nutrient loads during the 20th century is well documented and studied. However, in the Baltic Sea drainage area, humans have affected the environment longer than the environmental monitoring can provide data for. LÄS MER
18. Bioaerosols and their importance for low-level Arctic clouds
Sammanfattning : Bioaerosols are microorganisms or functional parts of them or other biological matter suspended in air. Examples are bacteria, viruses, pollen, spores, or smaller plant debris. In the atmosphere, bioaerosols can play various functional roles, such as facilitating the spread of genetic material. LÄS MER
19. Primary Marine Aerosol Production : An experimental study based on Arctic Ocean water and a sea water proxy
Sammanfattning : This thesis focuses on the interplay between the physical properties of ocean water and primary marine aerosol (PMA) emissions in the context of a rapidly changing Arctic climate. PMAs are an important part of the climate system due to their ability to interact with incoming solar radiation and to influence cloud properties. LÄS MER
20. Transport of Mercury Species in the Environment. Exchange between Oceanic Waters and the Atmosphere
Sammanfattning : Mercury is an element present in the earth crust as well as a component in the atmosphere. During centuries mercury has been released by natural sources, e.g. volcanic eruptions, evasion from water surfaces and degassing from soil. LÄS MER
