RV Investigator Voyage IN2018_V01 Underway UWY Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2018_V01, titled: "Detecting Southern Ocean change from repeat hydrography, deep Argo and trace element biogeochemistry & CAPRICORN." The voyage took place between January 11 and February 21, 2018 departing from Hobart (TAS) and arriving in Hobart.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 (csv format). Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Report for this voyage.本记录描述了从海洋国家设施（Marine National Facility, MNF）“调查者号”（RV Investigator）航次IN2018_V01获取的走航（Underway, UWY）数据，本次航次的主题为"基于重复水文观测、深层Argo浮标与痕量元素生物地球化学及CAPRICORN项目探测南大洋变化"。本次航次于2018年1月11日至2月21日开展，从塔斯马尼亚州霍巴特出发并最终返回霍巴特。 标准走航数据为连续记录模式，包含以下三类内容： (1) 导航数据（Navigation data, NAV）：纬度、经度、航速、艏向、对地航向、陀螺仪以及多普勒计程仪（双GPS仪器）； (2) 温盐仪（Thermosalinograph, TSG）数据：海水盐度、流速、水温、荧光值、二氧化碳分压（pCO2）、奥普托德传感器温度及溶解氧； (3) 大气观测数据（Atmospheric data, MET）：湿度、风速与风向（风标及超声传感器）、辐射计/海表温度、总日射表/太阳辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨、臭氧以及痕量气体（左舷与右舷仪器）。 数据以5秒为间隔进行记录。近实时数据可通过"走航数据可视化工具"链接获取。 本数据集已由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（Information and Data Centre, IDC）完成处理与归档。 数据集提供三种时间分辨率版本：5秒间隔（NetCDF格式）、10秒间隔及5分钟间隔（均为CSV格式）。 本数据集的补充信息详见本次航次的航次总结报告及/或数据处理报告。
