Results of side-scan sonar mapping within the framework of the German Coastal Engineering Research Council project AufMod (¿Aufbau integrierter Modellsysteme zur Analyse der langfristigen Morphodynamik in der Deutschen Bucht¿ [¿Development of integrated model systems for the analysis of long-term morphodynamics in the German Bight¿], 01.11.2009-31.12.2012): -survey lines of side-scan sonar surveys -grab stations for ground truthing -sediment maps

The “World Seabed Sediment Map” product contains geo-referenced digital data, describing the nature of the sediment encountered in different seas and oceans of the world. The objects are all surface areas and the description of an object includes in particular the nature of the sediment including rock-type bottoms.

Data were generated within the framework of the German Coastal Engineering Research Council project AufMod (¿Aufbau integrierter Modellsysteme zur Analyse der langfristigen Morphodynamik in der Deutschen Bucht¿ [¿Development of integrated model systems for the analysis of long-term morphodynamics in the German Bight¿], 01.11.2009-31.12.2012). Various sedimentological parameters processed as products for the German Bight area were calculated from interpolated grain size distributions: - "Median_Grain_Size": Median-Durchmesser (D50) der interpolierten Kornsummenkurve - "Mean_Grain_Size": Mittelwert des Korndurchmessers - "Sorting1": Sortierung after Trask (1932): sqrt(D75/D25) - "Sorting2": Sortierung after Folk and Ward (1957): (phi84-phi16)/4+(phi95-phi5)/6.6 - "Skewness": Skewness after Folk and Ward (1957): (phi16+phi84-2phi50)/2(phi84-phi16)+(phi5+phi95-2phi50)/2(phi95-phi5) - "Kurtosis": Kurtosis after Folk and Ward (1957): (phi95-phi5)/2.44(phi75-phi25) - "GSF_micrometer": content of sand fractions (half phi° intervals) [%], 63 to 2000 micrometers - "PredominantSandFractions": spatial distribution of sediment fractions with a coontent 50 % / 20 % - 50 %

Various paramters for analysing morphodynamics in the German Bight on the basis of a 32 years time series aof interpolated bathymatries (yeasr 1982 - 2012). The data were generated within the framework of the German Coastal Engineering Research Council project AufMod (¿Aufbau integrierter Modellsysteme zur Analyse der langfristigen Morphodynamik in der Deutschen Bucht¿ [¿Development of integrated model systems for the analysis of long-term morphodynamics in the German Bight¿], 01.11.2009-31.12.2012). - "Morphological Alteration": differences in depth between two annual topographies for different periods (1, 5, 10, 30 years periods). - "Morphological Space": maximum difference in height at each model grid point (Zmax-Zmin) for different periods (1, 5, 10, 30 years) - "Morphological Drive": Difference between the maximum and the minimum annual rate of change in the period under consideration ((dz/a)max-( dz/a)min); 1, 5, 10, 30 years). With this parameter, it is possible to make a declaration as to whether a morphological alteration constantly takes place throughout the period under consideration or extreme results have occurred - "Count Of Datasets": amount of field campaigns present in the respective period under consideration - "Considerd Period": Time interval which is actually covered with data within the period under consideration [decimal years]
