Abstract

The Wadden Sea is a dynamic natural environment located at the transition between the mainland marshes and the barrier islands fringing the open North Sea. The geomorphological processes and habitat characteristics of the area determine important functions in human-environmental relations and ecosystem services at local to global scales. However, the area-wide study of basic surface parameters is complicated by the tidal environment as such: Many areas are difficult to access and most classic air- or ship-borne surveying methods have crucial limitations, due to the temporal water coverage and the variable tidal geomorphology. This determines that the collection of field data is cumbersome and time consuming. Detailed appraisals of spatial patterns, processes and change are consequently limited in coverage or validity. We present first insights into the potential of an interdisciplinary approach combining a range of different methods to construct a spatially-consistent dataset of tidal geomorphological change and benthic habitat distribution. The study is based on a time-series of aerial images, hydroacoustic surveying and topo-bathymetric LiDAR data, which are supplemented by ancillary geodata to facilitate a comprehensive analysis of modern surface properties (elevation, sediment distribution, bedforms, biology) in the Sylt-Rømø Bight.
