QUALITY ASSESSMENT OF SEA LEVEL DATA by the UH SEA LEVEL CENTER/NATIONAL OCEANOGRAPHIC DATA CENTER JOINT ARCHIVE FOR SEA LEVEL updated 16 Aug 2019 Station : Cuxhaven, Steubenhoft Latitude: 53 52.0N Country : Germany Longitude: 008 43.0E JASL # : 825A Time Meridian: 015E (GMT + 1 hr) GLOSS # : 284 Originator #: NODC #: 15003801 Contributor : German Federal Institute of Hydrology (BfG) Am Mainzer Tor 1 Postfach 200253 56002 Koblenz Germany Originator : German Federal Waterways and Shipping Administration (WSV) Original Data: diagram paper Instrmnt Type: float Digitzd Intvl: 30 minutes using spline functions Present Data : Hourly, daily, and monthly values obtained by: Hourly : unconfirmed Daily : 119-point convolution filter (Bloomfield, 1976) centered on noon applied to the hourly data with respective periods of the 95, 50, and 5% amplitude points at 124.0, 60.2, and 40.2 hours Monthly: Simple average of all daily values; calculated if 7 or fewer days are missing Span of data : 29 Dec 1917 - 31 Dec 2018 Gaps > 1 mon : none Time Refernce: GMT (00-23 hours) Space-filler Flag :-9999 Units : millimeters Missing Data Flag : 9999 Existing : No Operational : No Sat. Trans. : No Distribution : 1917-2018 Refernce Levl: All data are referred to the Tide Gauge Zero (TGZ) TGZ = 5.019m below Normal Null (NN) Comment : The tidal analysis does not resolve all the harmonic constituents thus the residuals are noisy. The meteorological signal is exceptionally large in this area. Data Source: "German Federal Waterways and Shipping", communicated by the German Federal Institute of Hydrology (BfG). These data were quality checked and published by the gauge-operating WSV offices. Nevertheless, data errors and inconsistencies cannot be ruled out completely, so that neither the WSV nor the BfG do accept any liability for the correctness and completeness of the data.
