Continuous thermosalinograph oceanography along Heincke cruise HE549@en

Data obtained by a thermosalinograph (SBE21, SeaBird GmbH) and an external temperature sensor (SBE38, Sea-Bird GmbH) were processed to receive a validated data set of temperature and salinity on board RV Heincke during cruise HE549. Unvalidated data of conductivity sensor, internal and external temperature are extracted from the DAVIS SHIP data base (https://dship.awi.de) in a 1-second interval. The salinity was calculated using conductivity and internal temperature by applying the Practical Salinity Scale 1978 (PSS-78). After applying different filters, processed data are provided as 5min means of salinity and water temperature aligned with position data taken from master track of the respective cruise. For further details see the processing reports of each cruise.本数据集为Heincke号研究船（RV Heincke）在HE549航次期间，采用温盐计（thermosalinograph）SBE21（SeaBird GmbH）及外置温度传感器SBE38（Sea-Bird GmbH）采集的数据经处理后得到的经校验温盐数据集。未校验的电导率传感器、内置与外置温度传感器原始数据，以1秒为间隔从DAVIS SHIP数据库（DAVIS SHIP，https://dship.awi.de）中提取。本研究基于电导率与内置温度数据，结合1978实用盐度标度（PSS-78）计算得到盐度值。经多类滤波处理后，将盐度与海水温度的5分钟均值数据，与对应航次主航迹获取的位置数据进行匹配对齐，得到最终处理数据集。如需获取更多技术细节，请参阅各航次的处理报告。
