Duration: 2011 - 2015

In the view of the above the FTZ since 2011 conducts sedimentological mappings and recordings of the underwater topography in the main tidal channels of the National Park Schleswig-Holsteinisches Wattenmeer. Furthermore it is attempted to detect those habitats that arise from the sea floor like e.g. blue mussel beds to document the distribution and setting of these inhabited areas. The research is carried out under the order and in collaboration with the national park's administration.

For the mapping hydroacoustic devices like side scan sonar and specialized echo sounders are applied. The comprehensive but in matters of sediment distribution indirect hydroacoustic data (backscatter strength) are made comparable by information derived from discrete samples taken with sediment grabs or dredges. Based on expert knowledge and partly completed by the results of mathematical classification methods all outcomes are compiled into cartographic descriptions.

In this way besides some smaller focus areas the tidal channel system of the Piep (Büsum), outer Eider estuary, Norderhever (Pellworm), Heverstrom (Husum), Norderaue (Föhr/Amrum) and Hörnumtief (southern Sylt) were investigated. In 2015 surveys will be performed in the tidal basins of the Suederaue and the Rummelloch.
