资源简介:

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)研究船走航式海水流通系统中的、由美国海鸟科学公司(Sea-Bird Scientific, USA)生产的SBE21型温盐仪(SBE21 thermosalinograph)与辅助SBE38型温度传感器采集的原始数据处理得到,经处理后获得沿航迹的经校准与验证的海水温度与盐度数据集。海水进水口设置于2米水深处。原始十六进制数据从DAVIS SHIP数据库(DAVIS SHIP data base,https://dship.awi.de)下载,分辨率为1秒,随后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,移除异常值,并利用测量季结束后由海鸟科学公司开展的季后校准所得系数校正传感器漂移。盐度依据PSS-78实用盐度标度(PSS-78 Practical Salinity Scale),由内部温度、电导率及压力计算得到。处理后的数据以海水温度、电导率与盐度的1分钟均值形式提供,并与主航迹获取的位置数据对齐。质量标记依据SeaDataNet数据质量控制程序(SeaDataNet Data Quality Control Procedures,2010年5月版)附加至数据中。更多细节详见所附的处理报告。
