SMMS: Stratigraphy (1990, 2000, 2010, 2020)

Definition: “Stratigraphy” in this project refers to the physical properties of the water bottom over the depth of the grain size, distribution and storage. Waters in this context are seas, rivers or closed inland waters. Within the framework of the SMMS project, stratigraphic data sets are those that represent the sedimentological water base structure in the German Bay, including the estuaries of the Ems, Weser and Elbe estuaries. Through morphological activities of the water soil, such a stratigraphic model is only valid for a certain period of time or time. Data generation: Stratigraphic products form the basis for gridded time-variant surface sedimentological models, which are created using the functional soil model, a data-based hindcast simulation model, via spatial-temporal interpolation and specially developed sedientological extrapolation methods based on sea and land surveys of various data types as well as surface sedimentological sampling. Within these, erosion processes are simulated for a target time via the time-variant consideration, which thus represent a final state at a time. In areas where the model base simulated this way does not reach the model base (such as the Holocene base), the free space is filled with interpolated sediment cores. For the years 1990, 2000, 2010 and 2020, a gridded stratigraphic model with additional bathymetric information in 10 m resolution will be created for Deutsche Bucht. Product: A tiled 10 m grid of the German Bay valid on 01.07. for the year, wherein at each grid node the Phi quarter discrete modeled sum lines are deposited in 50 cm deep integrated successive intervals from the surface of the year to the model base. The product is provided in CSV format together with a GeoTiff of sedimentological variance at each node above depth.
