Continuous physical oceanography along SONNE cruise track SO248

Data presented here were collected with a PocketFerryBox (device 751502) during the cruise SO248 (BacGeoPac) with RV Sonne from Auckland, New Zealand to Dutch Harbor, USA (May 1st, 2016 to June 3rd, 2016). The FerryBox system used was equipped with: single temperature and conductivity probe (SBE 45, S/N 0526), a turbidity sensor (Seapoint Turbidity Meter, STM I87017_A), and a fluoroscence sensor (Seapoint Chlorophyll Fluorometer, SFC I87064). The sensors were pre-calibrated by the manufacturers. The FerryBox was by-passed to the shipboard seawater system, pumping water from the surface at approx. 6 m depth. The system was operated with a flow of approx. 6 L/min. The ship speed is given as an indicator for transect and station time during the cruise and was derrived from the onboard DSHIP system. Station data might be influenced by ship operation and manoeuvering and should be taken with care. Data were despiked, and visually checked. Reference samples for salinity correction were taken in defined intervals, and analysed in laboratory approx. 4 months after the cruise [n=24, R²=0.999]. The ship position was derived from the shipboard GPS-system. The time zone is given in UTC. All systems had to be stopped from the 4th of May (UTC 21:27) to the 6th of May (UTC 21:27).

本数据集所用数据采集自2016年5月1日至6月3日期间，搭载于“索恩号”（RV Sonne）科考船执行的SO248（BacGeoPac）巡航航次，使用PocketFerryBox（设备编号751502）完成采集，航次航线从新西兰奥克兰延伸至美国荷兰港。本次所使用的FerryBox系统搭载了以下传感器：单通道温度与电导率探针（SBE 45，序列号0526）、浊度传感器（Seapoint Turbidity Meter，型号STM I87017_A）以及荧光传感器（Seapoint Chlorophyll Fluorometer，型号SFC I87064），所有传感器均由厂商预先完成校准。该FerryBox系统旁路接入船载海水系统，从约6米深度的表层抽取海水，系统运行时的海水流量约为6 L/min。航次记录的船速用于指示断面与站位的时间节点，该数据源自船载DSHIP系统。站位数据可能受船舶操作与机动操纵影响，使用时需谨慎。所有数据均已完成野值剔除与目视检查。盐度校正所用的参考样品按预设间隔采集，并于航次结束后约4个月在实验室完成分析（样本量n=24，决定系数R²=0.999）。船舶位置数据源自船载GPS系统，时间采用协调世界时（UTC）标注。所有系统曾于协调世界时5月4日21:27至5月6日21:27期间停机。
