RV Investigator Voyage IN2020_V10 CTD Data

This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2020_V10, titled: "MNF Trials, Storm Bay Modelling and Information System Data Collection, and Bathymetric and Benthic Habitat mapping of the Huon AMP." The voyage took place between November 13 and November 22, 2020 departing from Hobart (TAS) and returning to Hobart.Data for 9 deployments were acquired using the Sea-Bird SBE911 CTD 24, fitted with 36 twelve litre bottles on the rosette sampler. Sea-Bird-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO -supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.The final conductivity calibration was based on a single deployment grouping. The final calibration from the secondary sensor had a standard deviation (SD) of 0.0011549 PSU, well within our target of ‘better than 0.002 PSU’. The standard product of 1 decibar binned averaged were produced using data from the secondary sensors.The dissolved oxygen primary sensor data calibration fit had a SD of 0.38919μM. The agreement between the CTD and bottle data was good.A PAR, Transmissometer, Chelsea Fluorometer, and Wetlabs Fluorometer were also installed on the auxiliary A/D channels of the CTD.The collected data were subsequently processed and archived within the CSIRO National Collections and Marine Infrastructure (NCMI) 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.

本记录记述了澳大利亚海洋国家设施“调查者号”（RV Investigator）航次IN2020_V10所采集的电导率-温度-深度（Conductivity-Temperature-Depth, CTD）数据，该航次主题为：“MNF试验、风暴湾建模与信息系统数据采集，以及休恩AMP（Huon AMP）的水深与底栖生境测绘”。本航次于2020年11月13日至11月22日开展，从塔斯马尼亚州霍巴特港启航并返回霍巴特。
本航次共完成9次CTD布放，所用设备为Sea-Bird SBE911型CTD 24，其搭载的采水器罗塞塔（rosette sampler）配备36个12升采水瓶。计算压力与初始电导率值时采用了Sea-Bird公司提供的校准系数；温度数据则应用了澳大利亚联邦科学与工业研究组织（CSIRO）提供的校准方案进行校正。
所有数据均经过自动化质量控制（QC）流程处理，以剔除尖峰值与超限数据。最终电导率校准基于单次布放分组开展，二级传感器的最终校准结果的标准偏差（SD）为0.0011549 PSU，远优于我们设定的“优于0.002 PSU”的目标阈值。研究团队基于二级传感器的数据，生成了1分巴（decibar）分箱平均的标准产品。
溶解氧一级传感器数据的校准拟合标准偏差为0.38919μM。CTD测量数据与采水瓶采样数据的吻合度良好。
CTD的辅助模数转换（A/D）通道还同步搭载了光合有效辐射（PAR）传感器、透射率计、Chelsea型荧光计与Wetlabs型荧光计。
所采集的全部数据均已完成处理，并归档于位于霍巴特的澳大利亚联邦科学与工业研究组织（CSIRO）国家海洋采集与基础设施（National Collections and Marine Infrastructure, NCMI）信息与数据中心（IDC）。
