RV Investigator Voyage IN2023_V06 Underway (UWY) Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2023_V06, titled "Understanding Eddy Interactions and Their Impacts in the East Australian Current System." The voyage took place between October 9, 2023 and November 2, 2023 (AEST), departing from Sydney and returning to Sydney.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 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).The quality-controlled RV Investigator underway meteorological and SST data are supplied to the IMOS AODN and other global data repositories and distributors, and made available for satellite SST validation by the Australian Bureau of Meteorology (BoM).Near real-time, unprocessed data are available via the link "Visualisation tool for Underway Data."This dataset has been processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Data are available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII format). Note: not all variables are quality controlled; please check for existing QC flags in the datasets. Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Reports for this voyage.

本记录描述了从澳大利亚国家海洋设施（Marine National Facility, MNF）“调查者号”（RV Investigator）科考航次IN2023_V06获取的走航（Underway, UWY）数据，该航次主题为“东澳大利亚洋流系统中涡旋相互作用及其影响研究”。本航次执行时间为2023年10月9日至2023年11月2日（澳大利亚东部标准时间，AEST），启航及终到港均为悉尼。标准走航数据采用连续记录模式，包含以下三类内容：(1) 导航数据（NAV）：纬度、经度、航速、航向、对地航向、陀螺罗经数据以及双GPS型多普勒计程仪数据。(2) 温盐仪（Thermosalinograph, TSG）：海水盐度、流量、水温、荧光强度、pCO2以及奥普特德传感器/溶解氧数据。(3) 气象数据（MET）：湿度、风速与风向（采用风标与超声传感器）、辐射计/海表温度、总辐射计/太阳辐射、光合有效辐射（PAR）、空气温度、气压、降雨量、臭氧以及痕量气体（左舷与右舷配套仪器）。经质量控制的“调查者号”走航气象及海表温度（Sea Surface Temperature, SST）数据已提交至IMOS AODN及其他全球数据仓储与分发机构，并供澳大利亚气象局（Bureau of Meteorology, BoM）开展卫星海表温度验证工作使用。近实时未处理数据可通过“走航数据可视化工具”链接获取。本数据集已完成处理与质量控制，并由澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）下属的国家海洋馆藏与基础设施信息数据中心（National Collections and Marine Infrastructure, NCMI IDC）完成归档。数据提供5秒（NetCDF格式）、5秒、10秒、1分钟及5分钟（ASCII格式）四种时间间隔版本。请注意：并非所有变量均经过质量控制，请核查数据集中已有的质量控制（Quality Control, QC）标记。有关本数据集的更多详细信息，请参阅本次航次的航次总结报告及/或数据处理报告。
