Abstract
Abstract. Marine spatial planning requires reliable data for, e.g., the design of coastal structures, research, or sea level rise adaptation. This task is particularly ambiguous in the German Bight (North Sea, Europe) because a compromise must be found between economic interests and biodiversity since the environmental status is monitored closely by the European Union. For this reason, we have set up an open-access, integrated marine data collection for the period from 1996 to 2015. It provides bathymetry, surface sediments, tidal dynamics, salinity, and waves for the German Bight and is of interest to stakeholders in science, government, and the economy. This part of a two-part publication presents data from numerical hindcast simulations for sea surface elevation, depth-averaged current velocity, bottom shear stress, depth-averaged salinity, wave parameters, and wave spectra. As an improvement to existing data collections, our data represent the variability in the bathymetry by using annually updated model topographies. Moreover, we provide data at a high temporal and spatial resolution (Hagen et al., 2020b); i.e., numerical model results are gridded to 1000 m at 20 min intervals (https://doi.org/10.48437/02.2020.K2.7000.0004). Tidal characteristic values (Hagen et al., 2020a), such as tidal range or ebb current velocity, are computed based on numerical modeling results (https://doi.org/10.48437/02.2020.K2.7000.0003). Therefore, this integrated marine data collection supports the work of coastal stakeholders and scientists, which ranges from developing detailed coastal models to handling complex natural-habitat problems or designing coastal structures.
Highlights
The North Sea on the northwest European shelf is a region where competing interests of economic growth and the protection of future ecosystem services collide
In Sievers et al (2021), we describe the calculation of annual bathymetry and decadal surface sediment data from observations and discuss limitations, data sources, and accuracy
All data products are distributed to users as offline and online solutions, i.e., web map service (WMS), web feature service (WFS), or online on-the-fly web visualization via THREDDS data server
Summary
The North Sea on the northwest European shelf is a region where competing interests of economic growth and the protection of future ecosystem services collide. Data products include sea surface elevation, depth-averaged current velocity, bed shear stress, depth-averaged salinity, wave parameters, and wave spectra in the German Bight at a high spatial (1000 m by 1000 m) and temporal (20 min intervals) resolution. Numerical modeling at this temporal and spatial scale has become possible with the availability of high-resolution bathymetry (Sievers et al, 2021), surface sediments, reanalyzed meteorology (Bollmeyer et al, 2015), and input from global modeling products such as FES. A list of all data products is given in Appendix A2
