Coastal lakes (CL) act as limnetic–?-oligohaline systems located on non-tidal coastlines in fresh and salt water mixing zone. Owing to considerable terrestrial nutrient input a high autochthonous productivity CLs release greenhouse gases (GHG) the ambient atmosphere, however, neither emission from system was assessed nor controls were recognized so far. In this study we attempted quantify diffu...

The intensity and magnitude of change that characterize coastal areas now demand the implementation of collective processes and tools to enhance coastal zone knowledge and management. Our hypothesis is that Coastal Spatial Data Infrastructures (CSDI) can contribute to Integrated Coastal Zone Management (ICZM) through a combination of technologies, policies and institutional arrangements to impr...

Stresses impacting the coastal zone in the Asia-Pacific region are briefly reviewed under the headings of sustainable coastal activities, coastal ecosystem management, community/resource interactions, coastal resource economics and sustainability, coastal area planning, and integrated coastal policies. Recent contributions on mitigation of these stresses are introduced, with emphasis on the Coa...

Submarine groundwater discharge (SGD) from subseafloor aquifers, through muddy sediments, was studied in Eckernförde Bay (western Baltic Sea). The fluid discharge was clearly traced by 222Rn enrichment in the water column and by the chloride profiles in pore water. At several sites, a considerable decrease in chloride, to levels less than 10% of bottom-water concentrations, was observed within ...

Background, Aims and Scope. The concentration of chlorinated dibenzo-p-dioxins and dibenzofurans in many fish from the Baltic requires monitoring, since it approaches or exceeds the European Union threshold limit value of 4 pg TEQ/g wet weight of fish for human consumption. The concentrations, expressed in TEQs, are important for toxicology and regulations, but hide the concentrations of the in...

Seagrasses are distributed across the globe and their communities may play key roles in the coastal ecosystems. Seagrass meadows are expected to benefit from the increased carbon availability which might be used in photosynthesis in a future high CO2 world. The main aim of this study was to examine the effect of elevated pCO2 on the net photosynthesis of seagrass Zostera marina in a brackish wa...

The climate changes in recent years in the southern Baltic have been resulting in an increased frequency of natural extreme phenomena (i.e. storms, floods) and intensification of abrasion processes, which leads to introduction of large amounts of sedimentary deposits into the marine environment. The aim of this study was to determine the mercury load introduced to the Baltic Sea with deposits c...
