High-Resolution Orthomosaics and Digital Elevation Models of Biogenic Structures in the German Wadden Sea

This dataset contains high-resolution (5 cm/pixel) orthomosaics and digital elevation models (DEMs) from unoccupied aerial vehicle (UAV) surveys of biogenic structures in the German Wadden Sea. Two Pacific oyster reefs (Kaiserbalje, Nordland) and one blue mussel bed (Nordstrand) were monitored between 2020 and 2022. The data, processed via structure from motion (SfM) and georeferenced, are provided as raster files (*.tiff), ready for GIS analysis. The Random Forest (RF) classification shapefiles support the mapping of biogenic structures. This dataset facilitates research on biogenic structure growth, sediment dynamics, and geomorphological processes in intertidal environments

Counts of amphipods, Fucus and Asian shore crabs at two sampling locations in the northern Wadden Sea

Field and Laboratory experiments were performed to study the feeding ecology of Hemigrpasus takanoi and C. maenas. Experiments were done between 2017-2020 on oyster reefs near the island of Sylt (Wadden Sea, North Sea). Data were collected to investigate the effect of a non-native crab species on native community. We used exclusion experiments in the field and feeding experiments under controlled conditions at the lab.
