RV Investigator Voyage IN2018_V07 Underway UWY Data

NOTE: THis voyage has been delayed from the planned departure date because of weather conditions at the deployment site.This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2018_V07, titled: "SOTS: Southern Ocean Time Series automated moorings for climate and carbon cycle studies southwest of Tasmania." The voyage took place between August 20 and August 24, 2018 departing from Hobart (TAS) and arriving in Hobart.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 Temprature, 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 where they are publicly available at the "Ships of Opportunity" Thredds server (http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/catalog.html) for research. From there, they are downloaded by NOAA for their In Situ Quality Monitoring web site (iQUAM2) and made available for satellite SST validation. The SBE 38 SST data are used within the Australian Bureau of Meteorology for real-time satellite SST validation and ingested into real-time SST analyses which are then used as the boundary condition for Numerical Weather Prediction models. The meteorological and SST data are uploaded onto the Global Telecommunications System (GTS) for global dissemination to Meteorological Agencies, and separately supplied to the SAMOS (http://samos.coaps.fsu.edu/html/) Project for air-sea flux research. The real-time SBE 38 SST data are currently (2017) used in the following data products (accessed via the GTS):• International Comprehensive Ocean-Atmosphere Data Set (ICOADS R3.0) (http://icoads.noaa.gov/) • NOAA NCEI Extended Reconstructed Sea Surface Temperature version 4 (ERSST.v4) (https://www.ncdc.noaa.gov/data-access/marineocean-data/extended-reconstructed-sea-surface-temperature-ersst-v4) • Hadley Centre SST Data Set (HadSST3) (http://www.metoffice.gov.uk/hadobs/hadsst3/)• Global Ocean Surface Underway Data (GOSUD) Project (http://www.gosud.org/) • Bureau of Meteorology daily and weekly SST analyses (http://www.bom.gov.au/marine/sst.shtml) • NOAA NCEI “Reynolds” daily global OISST analysis (https://www.ncdc.noaa.gov/oisst)• NASA JPL “MUR” 1 km daily global SST analysis (https://mur.jpl.nasa.gov/)• UK Met Office “OSTIA” daily global SST analysis (http://ghrsst-pp.metoffice.com/pages/latest_analysis/ostia.html)• CMC daily global SST analysis• Ourocean “G1SST” global daily 1 km SST analysis (https://ourocean.jpl.nasa.gov/SST)As part of the underway data gathering system, other datasets are produced (e.g., pCO2, ISAR SST) which are processed separately and have their own metadata records.Data are recorded at 5 second intervals. Near real-time data are available via the link "Visualisation tool for Underway Data." This dataset will be processed and archived within the CSIRO Oceans & Atmosphere (O&A) Information and Data Centre (IDC) in Hobart (TAS). Data are available at time intervals of 5 sec (NetCDF format), 10 sec and 5 min (ASCII format). Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Report for this voyage.

注意：本次航次因布放场地天气状况延误，未能按计划启航。本记录描述了从澳大利亚海洋国家设施（Marine National Facility, MNF）所属RV Investigator调查船的IN2018_V07航次采集的行进中（Underway）观测数据，航次标题为："SOTS：塔斯马尼亚州西南部用于气候与碳循环研究的南大洋时间序列自动锚系系统"（SOTS为Southern Ocean Time Series的缩写）。本次航次于2018年8月20日从塔斯马尼亚州霍巴特启航，于8月24日返回霍巴特。
标准行进中观测数据为连续采集内容，包含：
1. 导航数据（Navigation data, NAV）：纬度、经度、航速、航向、对地航向、陀螺仪数据以及多普勒计程仪（采用双GPS仪器）；
2. 温盐测量仪（Thermosalinograph, TSG）：海水盐度、流量、水温、荧光值、二氧化碳分压（pCO2）以及光学溶解氧传感器数据；
3. 大气观测数据（Atmospheric data, MET）：湿度、风速与风向（采用风标及超声波传感器）、辐射计/海表温度、总辐射表/太阳辐射、光合有效辐射（Photosynthetically Active Radiation, PAR）、气温、气压、降雨量、臭氧及痕量气体（左舷与右舷观测仪器）。
经质量管控的RV Investigator调查船行进气象与海表温度数据已提交至IMOS AODN，科研人员可通过"机遇航船（Ships of Opportunity）"Thredds服务器（http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/catalog.html）公开获取。美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）从该服务器下载数据，用于其原位质量监测网站（iQUAM2），并将其用于卫星海表温度验证工作。SBE 38型海表温度数据已被澳大利亚气象局（Australian Bureau of Meteorology）用于实时卫星海表温度验证，并接入实时海表温度分析系统，作为数值天气预报模型的边界条件。气象与海表温度数据已上传至全球电信系统（Global Telecommunications System, GTS），供全球气象机构共享，并另行提供给SAMOS项目（http://samos.coaps.fsu.edu/html/）用于海-气通量研究。
