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.本记录记述了取自澳大利亚国家海洋设施（Marine National Facility, MNF）所属‘调查者号’（RV Investigator）研究船IN2017_C01航次的航行同步（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”。本次航次于2017年4月11日至27日期间开展，从塔斯马尼亚州霍巴特港起航并最终返回霍巴特港。 标准航行同步数据为连续采集记录，包含以下内容： (1) 导航数据（Navigation data, NAV）：纬度、经度、航速、艏向、对地航向、陀螺仪数据以及双GPS型多普勒计程仪采集数据； (2) 温盐测量仪（Thermosalinograph, TSG）：水体盐度、流量、水温、荧光值、二氧化碳分压（pCO₂）、Optode探头温度与溶解氧数据； (3) 大气气象数据（Atmospheric, MET）：湿度、风速与风向（风向标与超声风速仪）、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（左舷与右舷仪器采集）数据。 数据采集间隔为5秒。用户可通过“航行同步数据可视化工具”链接获取近实时数据。本数据集已完成处理并归档于位于霍巴特港（塔斯马尼亚州）的澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气科学部（Oceans & Atmosphere, O&A）信息与数据中心（IDC）。本数据集提供三种时间分辨率版本：5秒间隔（NetCDF格式）、10秒间隔与5分钟间隔（均为ASCII格式）。有关本数据集的补充信息可查阅本次航次的航次总结报告及/或数据处理报告。
