Physical oceanography during SONNE cruise SO254 (PoriBacNewZ)

Data presented here were collected during the cruise SO254 (Project PoriBacNewZ) with RV Sonne from Auckland, New Zealand to Auckland, New Zealand (January 26th, 2017 to February 27th, 2017). In total, 13 vertical deep CTD-hauls were conducted. The CTD system used was a Sea-Bird Electronics Inc. SBE 911plus probe (SN 09-1266: SN 5828 / SN 4529). The CTD was attached to a SBE 32 Carousel Water Sampler (SN 32-1119) containing 24 20-liter Ocean Test Equipment Inc. bottles. The system was equipped with double temperature (SBE 3) and conductivity sensors (SBE 4), a pressure sensor (Digiquartz) an oxygen Optode (Aanderaa Optode 4831F), an altimeter (Benthos), and a chlorophyll fluorometer combined with a turbidity sensor (WET Labs ECO_AFL FL). The sensors were pre-calibrated by the manufacturers. Data were recorded with the Seasave V 7.5 software and processed using the SeaBird SBE Data Processing. Data were despiked, and also visually checked. The ship position was derived from the shipboard GPS-system linked to the CTD data. The time zone is given in UTC. Salinity was quality checked by reference samples [n=13], measured with an Optimare Precision Salinometer (OPS S/N 003) 4 month after the cruise (S1: R² 0.9997, S2: R² 0.9997).本数据集采集自2017年1月26日至2月27日期间执行的SO254航次（项目名称：PoriBacNewZ），搭载研究船松内号（RV Sonne）从新西兰奥克兰出发并返回奥克兰。本次航次共计开展13次垂直深层温盐深剖面（CTD，Conductivity Temperature Depth）拖曳采样。所用CTD系统为Sea-Bird Electronics Inc.生产的SBE 911plus型探头（序列号：SN 09-1266、SN 5828及SN 4529）。该CTD搭载了SBE 32型旋转式水样采集器（SBE 32 Carousel Water Sampler，序列号SN 32-1119），配套24个由Ocean Test Equipment Inc.生产的20升采水器瓶。本系统搭载的传感器包括：双通道温度传感器（SBE 3型）、双通道电导率传感器（SBE 4型）、Digiquartz型压力传感器、Aanderaa Optode 4831F型溶解氧光学传感器、Benthos型高度计，以及集成浊度传感器的WET Labs ECO_AFL FL型叶绿素荧光仪。所有传感器均由原厂完成预校准。数据通过Seasave V 7.5软件记录，并采用SeaBird SBE数据处理软件进行后期处理：首先对数据进行野值剔除，同时辅以人工目视检查。船舶位置通过与CTD数据联动的船载GPS系统获取，时间采用UTC（协调世界时）时区。盐度数据通过航次结束4个月后使用Optimare Precision Salinometer（OPS，序列号003）测得的13份标准参考样品开展质量校验，验证结果显示S1的决定系数R²=0.9997，S2的R²=0.9997。
