RV Investigator Voyage IN2015_E04 Underway UWY Data - (UNPROCESSED)

This record describes Underway (UWY) data collected from the Marine National Facility RV Investigator Event voyage IN2015_E04. This is a trace metals and micronutrients trial voyage for the RV Investigator departing Hobart on the 26th April and returning to Hobart on the 28th April, 2015.

Standard Underway data is continuously recorded (refer to Attributes Overview):
(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, and pCO2.
(3) Atmospheric (MET): Humidity, Wind speed and direction (vane and ultrasonic), Radiometer, Pyranometer, PAR, Air temperature, Air pressure, rain and optical 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 will not be processed, however raw unQC'd data can be supplied upon request. Additional information regarding this dataset is contained in the Cruise Summary Report for this voyage.

本记录涵盖了澳大利亚海洋国家设施（Marine National Facility）“调查者号”（RV Investigator）航次IN2015_E04所采集的走航（Underway, UWY）数据。本次航次为“调查者号”的痕量金属与微量营养物试验航次，于2015年4月26日从霍巴特起航，同年4月28日返回霍巴特。

标准走航数据为连续采集记录（详见属性概述）：
(1) 导航数据（Navigation, NAV）：纬度、经度、航速、航向、对地航迹向、陀螺罗经以及多普勒计程仪（双GPS仪器）。
(2) 温盐计（Thermosalinograph, TSG）：水体盐度、流量、水温、荧光值以及分压二氧化碳（pCO₂）。
(3) 气象数据（Atmospheric, MET）：湿度、风速与风向（风标与超声传感器）、辐射计、日射强度计、光合有效辐射（PAR）、气温、气压、降雨与光学降雨传感器数据、臭氧以及痕量气体（左舷与右舷仪器）。

数据采集间隔为5秒。用户可通过链接“走航数据可视化工具”获取近实时数据。

本数据集暂不进行处理，但可根据需求提供未经过质量控制的原始数据。有关本数据集的更多详细信息，详见本次航次的航次总结报告。
