RV Investigator Voyage IN2017_V01 Underway UWY Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator research voyage in2017_v01, titled "Interactions of the Totten Glacier with the Southern Ocean through multiple glacial cycles." The voyage took place from Hobart (TAS) to Hobart between the 14th January and 5th March, 2017. Standard Underway data is continuously recorded, it consists of: (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, 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.本数据集记录了2017_v01版本的"托滕冰川与南大洋在多个冰期旋回中的相互作用"航次中，澳大利亚海洋国家设施（Marine National Facility, MNF）"调查者号"（RV Investigator）科考船获取的航次走航（Underway, UWY）观测数据。本次航次于2017年1月14日至3月5日期间开展，往返于塔斯马尼亚州霍巴特（Hobart, TAS）。 标准走航观测数据为连续采集记录，包含以下三类内容： 1. NAV（导航数据）：基于双GPS系统获取的纬度、经度、航速、航向、地面航迹航向、陀螺罗经数据以及多普勒计程仪数据。 2. TSG（温盐计）：走航温盐仪数据，包括海水盐度、采样流量、水温、荧光强度以及二氧化碳分压（partial pressure of carbon dioxide, pCO2）。 3. MET（气象数据）：船左舷与右舷的大气观测数据，涵盖湿度、风速与风向（风向标与超声测风仪）、辐射计、总辐射表（Pyranometer）、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨情况、臭氧及痕量气体。 数据采样间隔为5秒。用户可通过下述链接获取近实时观测数据。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。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。有关本数据集的补充信息可查阅本次航次的航次报告及/或数据处理报告。
