Physical oceanography during RV HEINCKE cruise HE656@en

Conductivity-temperature-depth profiles were measured using a Seabird SBE 911plus CTD during RV HEINCKE cruise HE656. 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.本数据集基于海因克号（RV HEINCKE）科考航次HE656期间采用Seabird SBE 911plus型CTD系统采集的温盐深（Conductivity-Temperature-Depth, CTD）剖面数据。该CTD系统搭载了冗余传感器组，包括温度传感器（SBE3plus）、电导率传感器（SBE4）与溶解氧传感器（SBE43）。此外，该CTD系统还加装了其他配套传感设备：WET Labs C-Star型透射率仪、WET Labs ECO-AFL型荧光计，以及Teledyne (Benthos) 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，全年投入使用，航次结束后未开展航后校准，也未进行原位校准。其余所有传感器的校准均无固定周期。所有数据均关联至本次航次的站位日志，相关日志可通过DSHIP数据库获取。数据处理流程（含显著异常值剔除）严格遵循《海因克号RV HEINCKE CTD处理日志》（hdl:10013/epic.47427）中载明的操作规范。本数据集的处理报告链接如下。
