Physical oceanography during RV HEINCKE cruise HE622

Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE622. The CTD was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer and an altimeter (PSA-916 Teledyne (Benthos)) were mounted to the CTD. Temperature, conductivity and oxygen sensors are calibrated by the manufacturer once a year before being mounted in January. They are used throughout the year and no post-cruise or in-situ calibration is applied. All other sensors are calibrated irregularly. Data were connected to the station book of the specific cruise as available in the DSHIP database. Processing of the data including removal of obvious outliers followed the procedures described in CTD Processing Logbook of RV HEINCKE (hdl:10013/epic.47427). The processing report for this dataset is linked below.

本数据集通过赛博德（Seabird）SBE 911plus型温盐深剖面仪（Conductivity-Temperature-Depth，CTD），在研究型科考船“海因克号”（RV HEINCKE）航次HE622期间完成了电导率-温度-深度剖面数据的采集。该CTD搭载了温度（SBE3plus）、电导率（SBE4）与溶解氧（SBE43）的冗余传感器。此外，该设备还加装了额外传感器，包括WET Labs C-Star型透射仪、WET Labs ECO-AFL型荧光计，以及Teledyne（Benthos）公司生产的PSA-916型高度计。温度、电导率与溶解氧传感器每年1月装机前均由原厂进行一次校准，全年持续投入使用，且未开展航后校准或原位校准操作。其余所有传感器均实施不定期校准。所有数据已关联至对应航次的测站日志，该日志可于DSHIP数据库中查询获取。数据处理流程包含明显异常值剔除环节，严格遵循《“海因克号”科考船CTD数据处理日志》（hdl:10013/epic.47427）中载明的规范。本数据集的处理报告链接如下。
