1. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes
Sammanfattning : 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 dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. LÄS MER
2. Ecophysiological responses of Baltic and Atlantic Fucus vesiculosus to environmental factors
Sammanfattning : The Baltic Sea is a species-poor ecosystem where marine species coexist with freshwater species. The Baltic Sea offers low salinity, low content of inorganic carbon, long cold winters and no tides. LÄS MER
3. Physiological adaptations in two ecotypes of Fucus vesiculosus and in Fucus radicans with focus on salinity
Sammanfattning : The in origin intertidal marine brown alga Fucus vesiculosus L. grow permanently sublittoral in the brackish Bothnian Sea, side by side with the recently discovered F. radicans L. Bergström et L. LÄS MER
4. Iodine Isotopes (129I and 127I) in the Baltic Sea : Tracer applications & environmental impact
Sammanfattning : 129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. LÄS MER
5. Genetic Aspects of Environmental Disturbances in Marine Ecosystems : Studies of the Blue Mussel in the Baltic Sea
Sammanfattning : Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. LÄS MER
