Meteorological data of Time Series Station Spiekeroog for 2018

The Time Series Station Spiekeroog (TSS) was setup in 2002, in the tidal inlet between the East Frisian Islands of Langeoog and Spiekeroog in the Southern German Bight, at position 53°45′01.0″ N, 007°40′16.3″ E. The aim was to ensure the continuous measurement of physical, biological, chemical and meteorological parameters, even under extreme weather conditions such as storms, ice, and storm surges. The TSS was financed as part of the Deutsche Forschungsgemeinschaft (DFG) research unit BioGeoChemistry of Tidal Flats and the Ministry for Science and Culture of the Land of Lower Saxony (MWK). Here, air temperature, air pressure, relative humidity, wind speed and wind direction were measured in the year 2018. All raw data were revised and corrected for steps as range, outliers and stationarity checks. A detailed description of the Time Series Station Spiekeroog, its structure and instrumentation can be found in Zielinski et al. (2022) and in Reuter et al. (2009).

Continuous salinity observations at station BEFmate_S4low, 2019-09 to 2023-09

Data presented here were collected between 2019-09 and 2023-09 at station BEFmate_S4low within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems, https://uol.de/dynacom/ ) involving the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were established in the back-barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog (Germany). Salinity at different elevation zones was measured using conductivity loggers deployed in dip wells within experimental islands as well as in the saltmarsh enclosed plots. Measurements were obtained using HOBO U24 Conductivity Logger U24-002-C (Onset Computer Corporation, Bourne, MA/USA). All devices were pre-calibrated by the manufacturer. Logged data were retrieved in the field using a Hobo Underwater Shuttle (U-DTW-1) and were read out with the HOBOware Pro (V3.7.28) software. Salinity was derived in HOBOware Pro using temperature-dependent, nonlinear seawater conductivity compensation following the Practical Salinity Scale (PSS-78). Subsequent data processing was done using MATLAB (R2024b). Post-processing and quality control included (a) the removal of data covering maintenance activities, (b) the removal of implausible values using fixe thresholds (salinity > 40 psu and < 5 psu; temperature > 35 °C and < -5 °C), c) an outlier detection using the Hampel filter method, and (d) visual checks. Identified outliers were removed and synchronously removed across all associated parameters (temperature and salinity).

Continuous wave and tide observations at DynaCom artificial islands in the back-barrier tidal flat, Spiekeroog, Germany, 2022-09 to 2023-07

Data presented here were collected between September 2022 to July 2023 within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems, https://uol.de/dynacom/ ) of the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were created in the back barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog. Local tide and wave conditions were recorded with a RBRduo TDǀwave sensor (RBR Ltd., Ontario/Canada). The sensor was bottom mounted in a shallow tidal creek (0.77 m NHN) through a steel girder (buried 0.3m deep in the sediment) and was positioned 10 cm above sediment surface, as was determined by using a portable differential GPS. This resulted in the sensor falling dry during low tide. For accurate depth calculations, raw pressure data were manually corrected for atmospheric pressure derived from a locally installed weather station. The sensor was pre-calibrated by the manufacturer and the sampling rate was 3 Hz with 1024 samples per burst at a sample interval of 10 min. Recorded data were internally logged until the readout with the Ruskin (V1.13.13) software. Date and time is given in UTC. Data handling was performed according to Zielinski et al. (2018): Post-processing of collected data was done using MATLAB (R2018a). Quality control was performed by (a) erasing data covering maintenance activities, (b) removing outliers, and (c) visually checks. Low-tide data is not removed, but were easily identified through the manually calculated water depth data, where all depths < 0.05m represented low tide data.

Turbulenzgesteuerte sedimentäre Prozesse entlang eines hydrodynamischen Gradienten im Ostfriesischen Wattenmeer: Labor- und Geländeuntersuchungen

Dieses Forschungsvorhaben soll in Zusammenarbeit mit der Abteilung Meeresforschung des Forschungsinstitutes Senckenberg, mit Hilfe methodisch neuer sedimenthydraulischer Messungen einen Beitrag zum Grundlagenverständnis des Stoffhaushaltes im System Wattenmeer leisten und physikalische Eingangsparameter und Grenzwerte für den Beginn von Erosion und Sedimenttransport für die Modellierung dieser Küstenzone liefern. In der beabsichtigten Kombination von Labor- und Feldmessungen sollen jene hydraulischen Grenzzustände erfasst werden, in deren Bereich das Watt den weitgehend stabilen Zustand verlässt. Weiterführende und hierauf aufbauende Modelluntersuchungen werden dem geplanten Sonderforschungsbereich 1739 an der Universität Oldenburg vorbehalten. Der Einsatz der Turbulenzsonde (ADV, Acoustic Doppler Velocimeter, Fa. SONTEC) bietet zum ersten Mal die Möglichkeit, sohlnahe turbulente Strömungen im Labor und im Gelände quantitativ und standardisiert zu erfassen. Im Marburger Strömungs- und Wellenkanal sollen zunächst an natürlichen, aber sterilisierten Wattsedimenten die Wechselwirkungen zwischen dem Turbulenzmuster in der bodennahen Strömung unter einfachen monochromatischen Wellen und dem Sediment untersucht werden. Zugleich soll damit das Messverfahren kalibriert und standardisiert werden. In einem zweiten Schritt soll vergleichend über unterschiedlichen, auch kohäsiven und biogenen fixierten natürlichen Sedimenten der kritische Strömungszustand beim Bewegungsbeginn erfasst werden. In sechs aus dem Rückseitenwatt der Nordsee-Insel Spiekeroog ausgewählten und bereits eingemessenen Meßfeldern mit für den Ablagerungsraum typischen faziellen Mustern wird unter verschiedenen Strömungs- und Wellenbedingungen (Ebb- und Flutstrom, verschiedene Wassertiefen, Seegang, Wellenklima) die ADV-Sonde für dreidimensionale Strömungsmessungen eingesetzt. Parallel zu den bodennahen turbulenten Strömungsverhältnissen soll das Einsetzen von Erosion und Suspensionsentwicklung aufgezeichnet werden. Der Einfluss von Mikroorganismen auf Textur und Stabilität der Sedimentoberfläche soll parallel zu den Messungen verfolgt werden.

Continuous meteorological observations at DynaCom automatic weather station, Spiekeroog, Germany, 2025-01 to 2025-12

Data presented here were collected between January 2025 to December 2025 within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems, https://uol.de/dynacom/ ) of the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were created in the back barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog. Meteorological data were collected near the experimental setup, with a locally installed weather station located approximately 500m north of the southern shoreline. The weather station system used here was a ClimaSensor US 4.920x.00.00x that was pre-calibrated by the manufacturer (Adolf Thies GmbH & Co. KG, D-Göttingen). Data were recorded and saved within the Processcontrol Weather (c) -4H- JENA engineering GmbH (v20.1.0.1 2020) software in a sampling interval of 1 min, with an averaging time of 10 s. Date and time were given in UTC and the position was derived from the internal GPS system. Data handling was performed according to Zielinski et al. (2018): Post-processing of collected data was done using MATLAB (R2024b). Quality control was performed by (a) erasing data covering maintenance activities, (b) removing outliers, defined as data exhibiting changes of more than two standard deviations within one time step, and (c) visually checks.
