RV Investigator Voyage IN2022_V07 Underway (UWY) Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2022_V07, titled "HALO - Halimeda bioherm Origins, function and fate in the northern Great Barrier Reef." The voyage took place between August 15, 2022 and September 7, 2022 (AEST), departing from Brisbane and returning to Cairns.

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.

本记录记述了从澳大利亚国家海洋设施（Marine National Facility, MNF）‘调查者号’（RV Investigator）IN2022_V07航次采集的走航（Underway, UWY）数据，航次主题为《HALO——大堡礁北部仙掌藻生物礁的起源、功能与归宿》。该航次于2022年8月15日至2022年9月7日（澳大利亚东部标准时间，AEST）执行，从布里斯班启航，最终返回凯恩斯。

标准走航数据为连续观测记录，包含以下三类：
(1) 导航数据（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构型仪器）。
(2) 流动式温盐测量仪（Thermosalinograph, TSG）：海水盐度、流体流量、水温、叶绿素荧光强度、二氧化碳分压（pCO₂）以及Optode型溶解氧监测数据。
(3) 大气气象数据（MET）：相对湿度、风速与风向（叶片式与超声式传感器）、辐射计/海表温度（Sea Surface Temperature, SST）、总辐射计/太阳辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨量、臭氧浓度以及痕量气体（左舷与右舷配套观测仪器）。

经质量控制的‘调查者号’走航气象与海表温度数据，已提交至IMOS AODN及其他全球数据仓储与分发机构，同时供澳大利亚气象局（Australian Bureau of Meteorology, BoM）开展卫星海表温度验证工作使用。

未经处理的近实时数据可通过链接‘走航数据可视化工具’获取。

本数据集已完成质量控制处理，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（National Collections and Marine Infrastructure, NCMI）信息与数据中心（Information and Data Centre, IDC）完成归档。数据集提供5秒（NetCDF格式）、5秒、10秒、1分钟及5分钟（ASCII格式）的时间分辨率数据。请注意：并非所有变量均经过质量控制，请务必核查数据集中已有的质量控制标记（QC flags）。有关本数据集的补充信息详见本航次的航次总结报告及/或数据处理报告。
