Abstract

Ecosystems, such as the Baltic Sea, are particularly sensitive to changes in abiotic and biotic environmental factors. Because of the genesis and therefore its characteristics, such as salinity and species composition, the Baltic Sea is particularly vulnerable (Philippart 2007:39 ff). To understand this environment and to develop forecasts for the ecosystem, it is necessary that each of these factors and their interactions are well studied. Macroalgae are of high importance, because they serve as food and habitats for many animals of the ecosystem and that’s why they affect, directly and indirectly, the Baltic Sea. Remote sensing uses the reflection properties of vegetation, so that the first throw of the beach of macroalgae can be investigated. This process allows the analysis of large areas and can also be used for studies in the shallow waters. The combination of classical field and laboratory work with just this subdiscipline of geography link various data to a better understanding o f the complex ecosystem. Therefore the object of the thesis is the effect of changes of the abiotic and biotic factors of the ecosystem in the western Baltic Sea. For this reason the practical part is the development of a method for processing aerial photography using appropriate remote sensing software to determine the mass of seaweed washed up. In combination with field samples it should enable the Helmholtz Centre for Ocean Research Kiel to repeat a study of Grave & Möller and to carry out changes since the 1980s.
