surveying of geomorphology, sediment distribution and habitat properties in the Wadden Sea and in the coastal North Sea. To make area-based statements about the sediment properties of the seabed, we employ [...] Water Meets Land – Coastal Hydrography and Geology The Wadden Sea forms a transitional habitat between land and sea. High tidal amplitudes, shallow water depths, strong winds, and rivers discharge create [...] beneath the seabed and give us the opportunity to study the historical development of the very young North Sea on geological time scales. These methods help to visualize and analyze glacial surfaces and ancient
