RV Investigator Voyage IN2017_V02 Underway UWY Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2017_V02, titled: "SOTS: Southern Ocean Time Series Automated Moorings for Climate and Carbon Cycle Studies Southwest of Tasmania". The voyage took place between 17 to 30 March 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 will be 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海洋国家设施（Marine National Facility, MNF）「调查者号」科考船（RV Investigator）IN2017_V02航次获取的走航数据（Underway, UWY），航次标题为："SOTS：塔斯马尼亚岛西南海域用于气候与碳循环研究的南大洋时间序列自动化锚泊观测系统"。 本航次于2017年3月17日至30日开展，从塔斯马尼亚州霍巴特港启航并返回霍巴特港。 标准走航数据为连续采集数据，包含以下三类： 1. 导航数据（Navigation data, NAV）：纬度、经度、航速、艏向、对地航向、陀螺罗经数据以及多普勒计程仪（采用双GPS仪器）； 2. 温盐计（Thermosalinograph, TSG）：海水盐度、流量、水温、荧光强度、二氧化碳分压（pCO2）、光学溶解氧传感器（Optode）温度与溶解氧含量； 3. 大气观测数据（Atmospheric, MET）：相对湿度、风速与风向（配置风向标与超声波传感器）、辐射计/海表温度、总辐射表/太阳辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨量、臭氧以及痕量气体（配备左舷与右舷观测仪器）； 数据采集间隔为5秒。 可通过"走航数据可视化工具"链接获取近实时数据。 本数据集将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）海洋与大气研究中心（Oceans & Atmosphere, O&A）信息与数据中心（Information and Data Centre, IDC）进行处理与归档。 数据集提供三种时间分辨率的数据：5秒间隔（NetCDF格式）、10秒间隔以及5分钟间隔（ASCII格式）。 有关本数据集的更多详细信息，详见本航次航次总结报告及/或数据处理报告。
