Oceanographic data of Time Series Station Spiekeroog for 2012

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, sea level, water temperature and conductivity were measured in the year 2012. All raw data were revised and corrected for steps as range, outliers and stationarity checks.Water temperature and conductivity were measured in five different depths (4 m, 5.5 m, 7.5 m, 9.5 m, 11.5 m below MSL). Due to marine biofouling at the sensors and accompanying drift of instruments, the measured water temperature and conductivity data were corrected via linear regression by using reference data. As the water column in this region is well mixed and the water depth of the measurements varies with the tide, data from all five depths were averaged and referenced to a water depth of 4 m. Absolute salinity was derived from conductivity, temperature and pressure data according to TEOS 10. Data were smoothed and a quality flag was assigned for water temperature and salinity. The quality flags refer to the standard for data quality control of SeaDataNet https://www.seadatanet.org/ (0 = raw data, 1 = good data, 2 = probably good data, 3 = questionable data)..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).

施皮克勒奥格时序站（Time Series Station Spiekeroog，TSS）于2002年设立，选址位于德国湾南部东弗里西亚群岛兰格奥格岛与施皮克勒奥格岛之间的潮汐水道，坐标为53°45′01.0″N，007°40′16.3″E。该站点的设立目标是即便在风暴、海冰、风暴潮等极端天气条件下，也能持续监测物理、生物、化学及气象参数。

TSS的建设资金由德国研究基金会（Deutsche Forschungsgemeinschaft，DFG）潮滩生物地球化学研究单元以及下萨克森州科学与文化部（Ministry for Science and Culture of the Land of Lower Saxony，MWK）共同提供。2012年，该站点开展了海平面、水温与电导率的监测工作。所有原始数据均经过范围校验、异常值剔除和平稳性检验等流程，完成修正与校准。

本次监测中，水温与电导率的观测覆盖5个不同深度（平均海平面（Mean Sea Level，MSL）以下4 m、5.5 m、7.5 m、9.5 m及11.5 m）。由于传感器遭受海洋生物污损以及仪器随之出现的漂移，研究人员通过参考数据采用线性回归方法对实测水温与电导率数据进行了校正。鉴于该区域水体充分混合，且实测水深随潮汐动态变化，研究人员对5个深度的监测数据进行平均，并将其基准调整至4 m水深。

依据TEOS 10（海水热力学方程10）标准，由电导率、温度与压力数据推导得到绝对盐度。研究人员对数据进行平滑处理，并为水温与盐度数据赋予质量标识。该质量标识遵循SeaDataNet数据质量控制标准（https://www.seadatanet.org/），其中0代表原始数据，1代表优质数据，2代表疑似优质数据，3代表存疑数据。
