RV Investigator Underway UWY Data (Unprocessed)

This record describes some Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator, which are not part of research datasets and have not been processed or quality-controlled. This includes data from most "Gear trials" voyages (identified by the survey name suffix "_eNN"). Underway data from these voyages are usually not processed unless requested.While RV Investigator is at sea, standard Underway data are 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 and Optode/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).During the voyage, near real-time data are available from the MNF tool NRUD (Near Real-Time Underway Data) via the link "Visualisation tool for Underway Data" below. To request access after the voyage please contact the data custodian.The Underway data collected during research voyages (identified by the survey name suffix "_vNN") are processed and quality-controlled by the Marine National Facility (MNF). The processed datasets from these voyages are made available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII/CSV format) through a voyage-specific metadata record. Additional information regarding processed datasets is available in the Voyage Summary and/or the Data Processing Reports linked to the relevant metadata records.

本记录描述了从海洋国家设施（Marine National Facility, MNF）“调查者”号（RV Investigator）科考船采集的部分走航观测数据（Underway Data, UWY），此类数据不属于研究数据集范畴，且未经处理与质量控制。此类数据涵盖绝大多数“设备试验”航次的观测数据（航次名称以“_eNN”作为后缀标识），这类航次的走航观测数据通常不予处理，除非提出申请。当“调查者”号科考船处于航行状态时，标准走航观测数据会被持续记录，具体包括：(1) 导航数据（Navigation Data, NAV）：纬度、经度、航速、艏向、对地航向、陀螺罗经数据以及多普勒计程仪（双GPS仪器）。(2) 温盐测量仪（Thermosalinograph, TSG）：水体盐度、流量、水温、荧光强度、二氧化碳分压（pCO2）以及光学溶解氧传感器/溶解氧数据。(3) 气象观测数据（Atmospheric Data, MET）：湿度、风速与风向（由风标与超声风速仪采集）、辐射计/海表温度、总辐射表/太阳辐射量、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨量、臭氧数据以及左右舷采集的痕量气体数据。航次进行期间，可通过下方“走航数据可视化工具”链接，经由海洋国家设施的NRUD工具（近实时走航数据系统，Near Real-Time Underway Data）获取近实时观测数据。航次结束后如需获取数据权限，请联系数据管理员。针对研究航次采集的走航观测数据（航次名称以“_vNN”作为后缀标识），海洋国家设施（MNF）会对其进行处理与质量控制。这类航次的处理后数据集将通过专属航次元数据记录，以5秒（NetCDF格式）、5秒、10秒、1分钟及5分钟的时间间隔（ASCII/CSV格式）对外发布。有关处理后数据集的更多详细信息，可在关联相关元数据记录的航次总结报告及/或数据处理报告中查阅。
