1. SEA CHANGE Social-ecological co-evolution in Baltic Sea fisheries
Detta är en avhandling från Stockholm : Stockholm Resilience Centre, Stockholm UniversitySammanfattning : Sustainable management of natural resources requires an in-depth understanding of the interplay between social and ecological change. Linked social-ecological systems (SES) have been described as complex adaptive systems (CAS), which mean that they are irreducible, exhibit nonlinear dynamics, have interactions across scales and are uncertain and unpredictable.

2. Air-Sea Fluxes of CO2 Analysis Methods and Impact on Carbon Budget
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution. The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans. LÄS MER
3. Light conditions in seasonally ice-covered waters within the Baltic Sea region
Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant SciencesSammanfattning : Seasonal ice cover is a major driver of seasonality in aquatic ecosystems in the Baltic Sea region. Ice cover influences the underwater light conditions directly by limiting the light transfer and indirectly by modifying the mixing and circulation under the ice. LÄS MER
4. Mesoscale Processes over the Baltic Sea
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : The objective of this thesis is to study mesoscale processes above the Baltic Sea, which is a small, semi-enclosed sea where land-sea interaction may have a large impact on the offshore conditions. It is only the last tens of years that offshore research has become more popular, and one reason for this is the increasing offshore wind energy, which poses the need for accurate estimates of wind speed and turbulence conditions in the marine environment.

5. Macroalgae in the Baltic Sea responses to low salinity and nutrient enrichment in Ceramium and Fucus
Detta är en avhandling från Umeå : Ekologi och geovetenskapSammanfattning : The brackish Baltic Sea is a marginal environment for both marine and freshwater species. The rate of ecological differentiation is presumably high due to strong selection pressure from a gradient of decreasing salinity that has been present in its current state for only about 3 000 years.
