RV Investigator Voyage IN2017_V03 Underway UWY Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2017_V03, titled: "Sampling the abyss: latitudinal biodiversity patterns along the base of Australia’s eastern continental margin". The voyage took place between 15 May to 16 June 2017, departing from Bell Bay (TAS) and arriving in Brisbane (QLD).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.

本数据集记录了从澳大利亚国家海洋设施（Marine National Facility, MNF）“调查者号”（RV Investigator）IN2017_V03航次采集的航行中（Underway, UWY）数据，航次主题为“采样深渊：澳大利亚东部大陆边缘基底的纬度生物多样性模式”。该航次于2017年5月15日至6月16日期间执行，从塔斯马尼亚州贝尔贝港启航，最终抵达昆士兰州布里斯班港。

标准航行数据为连续记录，包含以下三类：(1) 导航数据（Navigation, NAV）：纬度、经度、航速、航向、对地航向、陀螺罗经数据以及双GPS型多普勒计程仪观测结果；(2) 温盐测量系统（Thermosalinograph, TSG）：海水盐度、流体流量、水体温度、荧光强度、分压二氧化碳（pCO2）、奥普特德水温传感器数据与溶解氧浓度；(3) 大气观测数据（Meteorological, MET）：相对湿度、风速与风向（风向标与超声风速仪）、辐射计/海表温度、总日射表/太阳总辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、大气温度、大气压强、降雨量、臭氧浓度以及痕量气体（左舷与右舷搭载仪器）观测数据。

数据采集间隔为5秒。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）完成处理与归档。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本航次的航次总结报告及/或数据处理报告。
