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.

本记录阐述了取自澳大利亚国家海洋设施（Marine National Facility, MNF）“调查者号”（RV Investigator）IN2017_V03航次的航次同步观测（Underway, UWY）数据，该航次主题为“探秘深渊：澳大利亚东部大陆坡基部的纬度生物多样性模式”。本航次开展于2017年5月15日至6月16日，起航于塔斯马尼亚州贝尔湾（Bell Bay, TAS），终抵昆士兰州布里斯班（Brisbane, QLD）。

标准航次同步观测数据为连续采集数据，包含以下类别：
（1）导航数据（Navigation data, NAV）：纬度、经度、航速、船首向、对地航向、陀螺传感器以及多普勒计程仪（双GPS仪器）。
（2）走航温盐仪（Thermosalinograph, TSG）：海水盐度、进水流速、水温、荧光值、分压二氧化碳（pCO2）、光学溶解氧传感器温度与溶解氧含量。
（3）大气观测数据（Atmospheric data, MET）：湿度、风速与风向（风向标及超声波传感器）、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、臭氧浓度以及痕量气体（左舷与右舷仪器）。

数据采集间隔为5秒。用户可通过“航次同步观测数据可视化工具”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（Commonwealth Scientific and Industrial Research Organisation, CSIRO）海洋与大气（Oceans & Atmosphere, O&A）信息与数据中心（Information and Data Centre, IDC）。本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。
