Continuous thermosalinograph oceanography along RV HEINCKE cruise track HE616

Raw data acquired by a thermosalinograph (SBE21, SeaBird GmbH) on board RV HEINCKE were processed to receive a calibrated and validated data set of seawater temperature and salinity. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) with a resolution of 1 sec. The SBE21 was equipped with an additional external temperature sensor (SBE38, Sea-Bird GmbH). Raw data are converted to temperature and conductivity values using the calibration coefficients from the calibration before deployment. However, data can only be finally processed after replacement and renewed calibration because correction values for the sensor drift can only be obtained by the post cruise calibration. The thermosalinograph on board RV HEINCKE is exchanged about once a year and calibration procedures are conducted after every exchange. Salinity was calculated according to the instructions from the Practical Salinity Scale PSS-78 using the obtained internal temperature and conductivity data. Processed data are provided as 1min means of salinity and seawater temperature aligned with position data taken from master track of the respective cruise. Quality flags are appended according to the SeaDataNet Data Quality Control Procedures (version from May 2010).

由‘海因克号’（RV HEINCKE）科考船搭载的走航温盐仪（thermosalinograph）采集的原始数据经处理后，得到经校准与验证的海水温度与盐度数据集。该数据集从DAVIS SHIP数据库（https://dship.awi.de）下载，原始数据的时间分辨率为1秒。该走航温盐仪型号为SBE21，制造商为SeaBird GmbH，且搭载了额外的外置温度传感器SBE38（Sea-Bird GmbH）。原始数据将基于部署前校准获得的校准系数，转换为温度与电导率数值。但由于传感器漂移的校正值仅能通过航后校准获取，因此数据集需在设备更换与重新校准后，方可完成最终处理。‘海因克号’科考船上的走航温盐仪约每年更换一次，且每次更换后均会执行校准流程。盐度计算依据实用盐标PSS-78（Practical Salinity Scale 78）的操作指南，通过采集到的内置温度与电导率数据完成。最终处理后的数据集以1分钟均值的形式提供盐度与海水温度数据，并与对应航次主航迹获取的位置数据进行匹配对齐。数据集将依据SeaDataNet数据质量控制流程（2010年5月版）附加质量标记。
