This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2018_V08, titled: "The Balleny mantle plume: key role in Tasmania-Antarctic breakup?" The voyage took place between December 27,2018 and January 10, 2019 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.
本记录描述了由澳大利亚海洋国家设施(Marine National Facility, MNF)的“调查者号”(RV Investigator)在IN2018_V08航次中采集的走航(Underway, UWY)数据,该航次主题为《巴伦尼地幔柱:塔斯马尼亚-南极裂解的关键作用?》。本航次执行时间为2018年12月27日至2019年1月10日,起航与终到港均为塔斯马尼亚州霍巴特市。
标准走航数据为连续采集记录,包含以下内容:(1) 导航(Navigation, NAV)数据:纬度、经度、航速、艏向、对地航向、陀螺传感器数据以及多普勒计程仪(双GPS仪器)。(2) 温盐仪(Thermosalinograph, TSG)数据:海水盐度、流量、水温、荧光强度、二氧化碳分压(pCO2)以及Optode/溶解氧数据。(3) 大气(Atmospheric, MET)数据:湿度、风速与风向(由风标及超声风速仪采集)、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、臭氧浓度以及痕量气体(由左舷与右舷仪器采集)。
经质量控制的“调查者号”走航气象与海表温度(Sea Surface Temperature, SST)数据已提交至澳大利亚综合海洋观测系统-澳大利亚海洋数据网络(IMOS AODN),相关数据可通过“机遇船舶”Thredds服务器(http://thredds.aodn.org.au/thredds/catalog/IMOS/SOOP/SOOP-ASF/VLMJ_Investigator/catalog.html)公开获取,以供科研使用。随后,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),并将数据开放用于卫星海表温度验证工作。
SBE 38型海表温度传感器采集的数据被澳大利亚气象局(Australian Bureau of Meteorology)用于实时卫星海表温度验证,并被纳入实时海表温度分析产品,作为数值天气预报模型的边界条件。上述气象与海表温度数据已上传至全球电信系统(Global Telecommunications System, GTS),以向全球各气象机构广播分发;同时,数据还单独提交给SAMOS项目(http://samos.coaps.fsu.edu/html/),用于海气通量相关研究。
截至2017年,实时SBE 38型海表温度数据已被应用于以下数据产品(可通过全球电信系统获取):

• Ourocean“G1SST”全球每日1公里分辨率海表温度分析产品(https://ourocean.jpl.nasa.gov/SST)
作为走航数据采集系统的一部分,本项目还生成了其他数据集(如二氧化碳分压pCO2、ISAR海表温度数据),这些数据集将进行单独处理,并拥有独立的元数据记录。
数据采集间隔为5秒。近实时数据可通过“走航数据可视化工具”链接获取。本数据集将由位于霍巴特市(塔斯马尼亚州)的澳大利亚联邦科学与工业研究组织海洋与大气(O&A)信息与数据中心(IDC)进行处理与归档。
数据集提供三种时间分辨率的数据:5秒间隔(NetCDF格式)、10秒间隔以及5分钟间隔(ASCII格式)。有关本数据集的更多详细信息,可查阅本航次的航次总结报告及/或数据处理报告。
