RV Investigator Voyage IN2022_V02 Underway (UWY) Data

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2022_V02, titled "Sedimentation at its extreme: how powerful are submarine caldera-forming eruptions (kermadec arc)?". The voyage took place between March 19 and April 19, 2022 departing from Hobart (TAS) and returning to Hobart (TAS).

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.

本数据集记录了海洋国家设施（Marine National Facility, MNF）“调查者号”科考船（RV Investigator）航次IN2022_V02采集的船载实时（Underway, UWY）数据，航次主题为《极端沉积作用：海底破火山口喷发的威力有多大（克马德克弧）？》。该航次于2022年3月19日从塔斯马尼亚州霍巴特港起航，同年4月19日返回霍巴特港。

标准船载实时数据为连续采集的序列，包含以下类别：
(1) 导航数据（Navigation, NAV）：纬度、经度、航速、船首向、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、流体流量、水温、荧光强度、分压二氧化碳（pCO₂）以及Optode型溶解氧监测数据。
(3) 大气气象数据（Meteorological, MET）：相对湿度、风速与风向（风标及超声传感器双测）、辐射计/海表温度、总日射表/太阳辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、空气温度、大气压强、降雨量、臭氧浓度以及痕量气体数据（配备左舷、右舷两套观测仪器）。

经质量控制的“调查者号”船载气象及海表温度（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（Australian Bureau of Meteorology, BoM）开展卫星海表温度验证工作。

近实时未处理数据可通过“船载数据可视化工具”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（CSIRO）国家海洋馆藏与基础设施信息数据中心（National Collections and Marine Infrastructure, NCMI; 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。有关本数据集的补充信息，请参见本航次的航次总结报告及/或航次数据处理报告。
