The digital terrain model of waterways for the estuary of river Elbe (DGM-W 2016) in high resolution based on airborne laser scanning and echo sounder data is produced and published by the German Federal Waterways and Shipping Administration (Wasserstraßen- und Schifffahrtsverwaltung des Bundes, WSV). The data includes the Outer Elbe and the tidally influenced side branches of the Elbe estuary upstream to the town Geesthacht. The data is available in a raster resolution of 1 meter. Coordinate reference system: EPSG 25852, ETRS89 / UTM Zone 32N Elevation reference system: DHHN92, NHN Survey methods: Airborne laser scanning (ALS) 02. - 04.2016 Multibeam echo sounder, single beam echo sounder 2015-2017 It is strongly recommended to use the data source map for quality assessment.

The digital terrain model of waterways for the estuary of river Elbe (DGM-W 2022) in high resolution based on airborne laser scanning and echo sounder data is produced and published by the German Federal Waterways and Shipping Administration (Wasserstraßen- und Schifffahrtsverwaltung des Bundes, WSV). The data includes the Outer Elbe and the tidally influenced tributaries and branches of the Elbe estuary upstream to the town Geesthacht. The data is available in a raster resolution of 1 meter. Coordinate reference system: EPSG 25852, ETRS89 / UTM Zone 32N Elevation reference system: DHHN2016, NHN Survey methods: Airborne laser scanning (ALS) 02.04.2022 - 19.04.2022 Multibeam echo sounder, single beam echo sounder 09.02.2017 - 09.04.2023 It is strongly recommended to use the data source map for quality assessment.

Der Datensatz enthält den täglichen Abfluss in Versen und ist repräsentativ für die Tideems. Messungen des Wasserstands in Versen erfolgen durch die Wasserstraßen- und Schifffahrtsverwaltung (WSV) und werden anschließend durch den Niedersächsischen Landesbetrieb für Wasserwirtschaft, Küsten- und Naturschutz (NLWKN) plausibilsiert und zum Oberwasserzufluss umgerechnet und bereitgestellt. English: The dataset contains daily river discharge data for Versen and is representative of the Ems estuary. Water level measurements in Versen are carried out by the Federal Waterways and Shipping Administration (WSV) and then validated, converted to river discharge and made available by the Lower Saxony State Agency for Water Management, Coastal Protection and Nature Conservation (NLWKN).

Dieser Datzensatz enthält die täglich akkumulierte Soleeinleitung bei Ditzum und Rysum. Die Daten wurden durch den Niedersächsischen Landesbetrieb für Wasserwirtschaft, Küsten- und Naturschutz (NLWKN) digitalisiert und in kontinuierliche Zeitreihen umgewandelt. Diese Zeitreihen wurden anschließend durch die BAW täglich summiert und in einem Datensatz zusammengefasst. English: This data set contains the daily accumulated brine discharge at Ditzum and Rysum. The data was digitized by the Lower Saxony State Agency for Water Management, Coastal Protection, and Nature Conservation (NLWKN) and converted into a continuous time series. These time series were then daily summarized by the BAW and compiled into a single data set.

Der Datensatz enthält Zeitreihen des Salzgehalts gemessen an 8 Stationen (Knock, Emden, Pogum, Gandersum, Terborg, Leerort, Weener und Papenburg) in der Tideems für den Zeitraum 2000-2024. Die Zeitreihen wurden durch den Niedersächsischen Landesbetrieb für Wasserwirtschaft, Küsten- und Naturschutz (NLWKN) zur Verfügung gestellt. Eine zusätzliche Korrektur der Außreißer und eine Umrechnung in absoluten Salzgehalt (S_A) erfolgte durch die BAW. Die Zeitreihen liegen in UTC+01:00 vor. Die Zeitreihen enthalten Zeiträume in denen das Sperrwerk in Gandersum geschlossen war. English: The dataset contains time series of salinity measured at eight stations (Knock, Emden, Pogum, Gandersum, Terborg, Leerort, Weener, and Papenburg) in the Tideems for the period 2000–2024. The time series were provided by the Lower Saxony State Agency for Water Management, Coastal Protection and Nature Conservation (NLWKN). Additional correction of outliers and conversion to absolute salinity (S_A) was carried out by the BAW. The time series are available in UTC+01:00. The time series include periods during which the Ems storm barrier in Gandersum was closed.

Classilied polygon data set of various sedimentological parameters for the German Bight area. Polygons are based on a triangulated model grid (spatial resolution: 250 m * 250 m). Parameters: - "Median_Grain_Size": median grain size (D50) of interpolierted grain size distribution, - "Mean_Grain_Size": mean grain size´ of interpolierted grain size distribution, - "Sorting1": sorting after Trask (1932): sqrt(D75/D25) - "Sorting2": sorting 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 grad intervals) [%], 63 to 2000 micrometers - "PredominantSandFractions": spatial distribution of sediment fractions with a coontent 50 % / 20 % - 50 %. Data were generated within the framework of the German Coastal Engineering Research Council project AufMod ("Development of integrated model systems for the analysis of long-term morphodynamics in the German Bight", 01.11.2009-31.12.2012).
