Short description:

Changes in the environmental conditions due to sea level fluctuations, increase in storminess, euthrophication, exploitation of resources or construction works are firstly reflected in the coastal areas. The shallow water environments of the Baltic Sea coast of Schleswig Holstein are an alteration of sandy environments offshore lowlands and hard bottom substrates offshore active cliffs. The latter are partly covered with stones of different size and with dif-ferent spatial distribution. Depending on the exposure of the coastline, these relict sediments, which are an indicator of ongoing erosion and reworking of glacial deposits, can be observed down to 20 m water depth. Especially stones, which have been exploited for more than 100 years until 1976, are an extremely valuable habitat, recognized by several national and inter-national regulations and directives. The ascertainment of stones, their impact on the seafloor and their behaviour as an ecological habitat due to environmental changes is the main objec-tive of this research program.
