RV Investigator Voyage IN2017_C01 Underway UWY Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2017_C01, titled: "Great Australian Bight deep water geological and benthic ecology ". The voyage took place between 11 to 27 April 2017 departing from Hobart (TAS) and returning to Hobart (TAS).Standard Underway data is continuously recorded, consisting of:(1) Navigation data (NAV): Latitude, Longitude, Speed, Heading, Course Over Ground, Gyros, and Doppler Log (dual GPS instrument).(2) Thermosalinograph (TSG): Water Salinity, Flow-Rate, Temperature, Fluorescence, pCO2, Optode temperature and Oxygen.(3) Atmospheric (MET): Humidity, Wind Speed and Direction (vane and ultrasonic), Radiometer/Sea Surface Temperature, Pyranometer/Solar Radiation, Photosynthetically Active Radiation (PAR), Air Temperature, Air Pressure, Rain, Ozone and Trace Gases (port and starboard instruments). Data are recorded at 5 second intervals. Near real-time data are available via the link "Visualisation tool for Underway Data." This dataset has been processed and archived within the CSIRO Oceans & Atmosphere (O&A) Information and Data Centre (IDC) in Hobart (TAS). Data are available at time intervals of 5 sec (NetCDF format), 10 sec and 5 min (ASCII format). Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Report for this voyage.

本记录描述了从澳大利亚国家海洋设施（Marine National Facility, MNF）所属“调查者号”研究船（RV Investigator）航次IN2017_C01获取的航行途中（Underway, UWY）数据，该航次主题为“大澳大利亚湾深水地质与底栖生态学研究”。本航次于2017年4月11日至27日开展，从塔斯马尼亚州霍巴特出发并最终返回霍巴特。

标准航行途中数据为连续采集记录，包含以下三类：
1. 导航数据（Navigation, NAV）：纬度、经度、航速、船首向、对地航向、陀螺罗经数据以及多普勒计程仪（双GPS仪器）采集数据。
2. 温盐监测仪（Thermosalinograph, TSG）：海水盐度、海水流量、水温、荧光强度、二氧化碳分压（pCO₂）、Optode探头温度与溶解氧浓度。
3. 大气气象数据（Atmospheric, MET）：空气湿度、风速与风向（风标与超声波传感器采集）、辐射计/海表温度、总日射表/太阳辐射量、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降水量、臭氧浓度以及痕量气体（左舷与右舷仪器采集）。

上述数据以5秒为间隔进行记录。用户可通过“航行数据可视化工具”链接获取近实时数据。本数据集已由位于塔斯马尼亚州霍巴特的澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气（Oceans & Atmosphere, O&A）信息与数据中心（IDC）完成处理并归档。本数据集提供三种时间分辨率版本：5秒间隔格式（NetCDF格式）、10秒间隔格式与5分钟间隔格式（均为ASCII格式）。有关本数据集的补充信息可查阅该航次的航次总结报告及/或数据处理报告。
