Continuous thermosalinograph oceanography along RV HEINCKE cruise track HE573@en

Raw data acquired by an SBE21 thermosalinograph and an auxiliary SBE38 temperature sensor (Sea-Bird Scientific, USA) installed in an underway seawater flow-through system on board RV Heincke were processed to yield a calibrated and validated data set of seawater temperature and salinity along the cruise track. The seawater inlet is located at a depth of 2 m. The raw hexadecimal data were downloaded from the DAVIS SHIP data base (https://dship.awi.de) at a resolution of 1 s, and converted to temperature and conductivity using the pre-deployment factory calibration coefficients. The converted data were averaged to 1 min values, outliers were removed, and sensor drift was corrected using coefficients obtained from a post-season calibration performed at Sea-Bird at the end of the measurement season. Salinity was calculated from internal temperature, conductivity and pressure according to the PSS-78 Practical Salinity Scale. Processed data are provided as 1 min means of seawater temperature, conductivity and salinity, aligned with position data taken from the master track. Quality flags are appended according to the SeaDataNet Data Quality Control Procedures (version from May 2010). More details are described in the attached processing report.本数据集由安装于海因克号（RV Heincke）科考船走航海水流通系统中的SBE21型走航温盐计（SBE21 thermosalinograph）与辅助SBE38型温度传感器（SBE38 temperature sensor，美国Sea-Bird Scientific公司生产）采集的原始数据处理得到，最终生成沿航迹分布的经校准与验证的海水温度、盐度数据集。海水采样入口位于水下2米深度处。原始十六进制数据从DAVIS SHIP数据库（https://dship.awi.de）下载，采样分辨率为1秒，并通过部署前的工厂校准系数转换为温度与电导率数据。将转换后的数据平均为1分钟均值，剔除异常值，并利用测量季末于Sea-Bird公司完成的季后校准所得系数修正传感器漂移。盐度依据PSS-78实用盐标（PSS-78 Practical Salinity Scale），由实测温度、电导率与压力计算得到。处理后的数据以1分钟均值形式提供，包含海水温度、电导率与盐度，并与主航迹获取的位置数据对齐匹配。数据附带的质量标记依据SeaDataNet数据质量控制流程（2010年5月版）生成。更多细节详见随附的处理报告。
