The German Bight located within the central North Sea is a hydro- and morphodynamically highly complex system of estuaries, barrier islands, and part of the world's largest coherent tidal flats, the Wadden Sea. To identify and understand challenges faced by coastal stakeholders, such as harbor operators or governmental agencies, to maintain waterways and employ numerical models for further analyses, it is imperative to have a consistent database for both bathymetry and surface sedimentology. Current commercial and public data products are insufficient in spatial and temporal resolution and coverage for recent analysis methods. Thus, this first part of a two-part publication series of the German joint project EasyGSH-DB describes annual bathymetric digital terrain models at a 10 m gridded resolution for the German North Sea coast and German Bight from 1996 to 2016 (Sievers et al., 2020a, https://doi.org/10.48437/02.2020.K2.7000.0001), as well as surface sedimentological models of discretized cumulative grain size distribution functions for 1996, 2006, and 2016 on 100 m grids (Sievers et al., 2020b, https://doi.org/10.48437/02.2020.K2.7000.0005). Furthermore, basic morphodynamic and sedimentological processing analyses, such as the estimation of, for example, bathymetric stability or surface maps of sedimentological parameters, are provided (Sievers et al., 2020a, b, see respective download links).

德国湾综合海洋数据收集 - 第 1 部分:水下地貌学和表层沉积学(1996-2016 年)

位于北海中部的德国湾是一个由河口、障壁岛和世界上最大的连贯潮滩瓦登海组成的高度复杂的流体和形态动力学系统。为了识别和理解沿海利益相关者(例如港口运营商或政府机构)在维护水道和采用数值模型进行进一步分析方面面临的挑战,必须为水深测量和表面沉积学建立一致的数据库。当前的商业和公共数据产品在空间和时间分辨率以及最近分析方法的覆盖范围方面都不足。因此,德国联合项目 EasyGSH-DB 的两部分出版物系列的第一部分描述了 10 m处的年度测深数字地形模型。 1996 年至 2016 年德国北海海岸和德国湾的网格分辨率(Sievers 等人,2020a,https://doi.org/10.48437/02.2020.K2.7000.0001),以及离散累积颗粒的表面沉积学模型1996、2006和 2016 年在 100 m网格上的尺寸分布函数 (Sievers 等,2020b,https://doi.org/10.48437/02.2020.K2.7000.0005)。此外,还提供了基本的形态动力学和沉积学处理分析,例如估计水深稳定性或沉积学参数的表面图(Sievers 等人,2020a、b,参见相应的下载链接)。
