RV Investigator Voyage IN2015_V02 Underway UWY Data

This record describes Underway (UWY) data collected from the Marine National Facility RV Investigator Voyage IN2015_V02. This is the second research voyage for the RV Investigator departing Sydney on the 15th May and arriving in Brisbane on the 26th May, 2015.

Standard Underway data is continuously recorded (refer to Attributes Overview):
(1) NAV: Navigation data: (dual GPS) Latitude, Longitude, Speed, Heading, course over ground, Gyros, and Doppler Log.
(2) TSG: Thermosalinograph: Water Salinity, flow-rate, Temperature, Fluorescence, and pCO2.
(3) MET: Atmospheric (port and starboard): Humidity, Wind speed and direction (vane and ultrasonic), Radiometer, Pyranometer, PAR, Air temperature, Air pressure, Optical Rain, Ozone and Trace gases.

Data are recorded at 5 second intervals. Near real-time data is available via the link below. This dataset will be processed and archived within the CSIRO Oceans & Atmosphere Data Centre in Hobart. Data is available in 5sec intervals in NetCDF, 10 sec and 5 min intervals in ascii format.
Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report.

本记录记述了从海洋国家设施“调查者号”（RV Investigator）科考航次IN2015_V02采集的走航（Underway, UWY）数据。该航次为“调查者号”的第二次科研航行，于2015年5月15日从悉尼启航，同年5月26日抵达布里斯班。

标准走航数据为连续采集记录（详见属性概览）：
(1) NAV：导航数据（双GPS系统）：纬度、经度、航速、艏向、对地航向、陀螺罗经以及多普勒计程仪。
(2) TSG：温盐仪（Thermosalinograph）：海水盐度、流量、水温、荧光强度以及分压二氧化碳（pCO2）。
(3) MET：大气观测数据（左舷与右舷）：湿度、风速与风向（风标与超声测风）、辐射计、总日射表（Pyranometer）、光合有效辐射（PAR）、气温、气压、光学雨量计、臭氧与痕量气体。

本数据集的采样间隔为5秒。用户可通过下述链接获取近实时数据。本数据集将由位于霍巴特的澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气数据中心进行处理与归档。该数据集提供5秒间隔的NetCDF格式文件，以及10秒、5分钟间隔的ASCII格式文件。
