RV Investigator Voyage IN2016_T01 CTD Data

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2016_T01, titled: "Continuity of Australian terranes into Zealandia: towards a geological map of the east Gondwana margin". The voyage took place from Laukota (Fiji) to Hobart (TAS) between June 30 and July 14, 2016.

Data for 13 deployments were acquired using the Seabird SBE911 CTD 20, fitted with 36 twelve litre bottles on the rosette sampler. CSIRO supplied calibrations were applied to the temperature, conductivity, oxygen, and pressure data. The data were subjected to automated QC to remove spikes and out-of-range values.

During cast 1, a communications error occurred at a depth of 250m (alarm on the deck unit) and the CTD was recovered. All other casts proceeded without issue. The calibrations derived from bottle samples from subsequent casts were applied to cast 1.
There were no changes to the sensor package for the duration of the voyage. The final calibration from the secondary sensor for casts 2-13 had a standard deviation (S.D) of 0.0012559 PSU, well within our target of ‘better than 0.002 PSU’.

The final calibration from the secondary dissolved Oxygen sensor for casts 2-13 had a standard deviation (S.D) 0.65093 uM/l. The agreement between the CTD and bottle data was good. The standard product of 1 dbar binned averaged were produced using data from the secondary temperature and conductivity sensors, and the secondary Oxygen sensor. A Fluorometer, Transmissometer, and altimeter were also installed and logged on the auxiliary A/D channels of the CTD.

The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.

本记录描述了从澳大利亚国家海洋设施“调查者号”（RV Investigator）航次IN2016_T01采集的电导率-温度-深度（Conductivity-Temperature-Depth, CTD）数据，航次主题为“澳大利亚地体向西兰洲的连续性：构建东冈瓦纳边缘地质图（Continuity of Australian terranes into Zealandia: towards a geological map of the east Gondwana margin）”。该航次于2016年6月30日至7月14日期间执行，航行路线从劳科塔（斐济）至霍巴特（塔斯马尼亚州）。

本次航次共完成13次布放作业，采用搭载36个12升采水器的罗塞塔采样器（rosette sampler）配套的Seabird SBE911型CTD 20采集数据。数据的温度、电导率、溶解氧及压力参数均采用了联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）提供的校准参数。所有数据均经过自动化质量控制（QC）流程，以剔除异常尖峰及超限值。

在第1次站位投放过程中，甲板单元于250米水深处发生通信故障并触发警报，随后回收了CTD设备。其余所有站位投放均顺利完成。我们将后续站位的采水器样本校准参数应用于第1次站位的数据。航次全程未对传感器组件进行任何改动。针对站位2至13的二级传感器，其最终校准结果的标准偏差（S.D.）为0.0012559 PSU，远优于我们“优于0.002 PSU”的目标精度。

针对站位2至13的二级溶解氧传感器，其最终校准结果的标准偏差为0.65093 uM/l。CTD数据与采水器样本数据的吻合度良好。我们利用二级温度、电导率传感器及二级溶解氧传感器的数据，生成了1分巴（dbar）分箱平均的标准产品。本系统同时搭载了荧光计、透射率计及高度计，并通过CTD的辅助模数转换（A/D）通道进行数据记录。

采集所得数据后续已完成处理，并归档于位于霍巴特的联邦科学与工业研究组织海洋与大气（Oceans and Atmosphere, O&A）信息与数据中心（Information and Data Centre, IDC）。有关本数据集的更多信息可参阅《航次摘要》及《CTD数据处理报告》。
