This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2018_T01, titled: "Physical and biogeochemical gradients in the East Australian Current." The voyage took place between April 6 and April 14, 2018 departing from Hobart (TAS) and arriving in Brisbane (QLD).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.
本记录描述了从澳大利亚国家海洋设施(Marine National Facility, MNF)的「调查者号」(RV Investigator)科考船IN2018_T01航次采集的走航(Underway, UWY)数据,航次标题为《东澳大利亚海流中的物理与生物地球化学梯度》。该航次于2018年4月6日至4月14日开展,从霍巴特(塔斯马尼亚州,TAS)出发,最终抵达布里斯班(昆士兰州,QLD)。
标准走航数据为连续记录数据集,包含以下类别:
1. 导航数据(NAV):纬度、经度、航速、船首向、对地航向、陀螺仪以及多普勒计程仪(双GPS仪器)。
2. 流动式温盐测量仪(Thermosalinograph, TSG)数据:海水盐度、流体流速、水温、荧光强度、二氧化碳分压(pCO₂)以及Optode光学溶解氧传感器数据。
3. 大气气象数据(MET):湿度、风速与风向(风向标与超声传感器)、辐射计/海表温度传感器、总日射表/太阳辐射、光合有效辐射(PAR)、空气温度、大气压力、降雨量、臭氧以及痕量气体(左舷与右舷仪器)。
经过质量控制的「调查者号」走航气象与海表温度(Sea Surface Temperature, SST)数据已提交至IMOS海洋数据网络(IMOS AODN),并可在「机遇船舶(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,供科研使用。
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),并供卫星海表温度验证使用。SBE 38型海表温度传感器数据被澳大利亚气象局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式的边界条件。
该气象与海表温度数据已上传至全球电信系统(Global Telecommunications System, GTS),供全球气象机构获取,同时还单独提供给SAMOS项目(http://samos.coaps.fsu.edu/html/)用于海气通量研究。
截至2017年,实时SBE 38型海表温度数据已被应用于以下可通过全球电信系统获取的数据产品:
• 国际综合海洋-大气数据集(ICOADS R3.0)(http://icoads.noaa.gov/)
• 美国国家海洋和大气管理局国家环境信息中心(NOAA NCEI)扩展重建海表温度版本4(ERSST.v4)(https://www.ncdc.noaa.gov/data-access/marineocean-data/extended-reconstructed-sea-surface-temperature-ersst-v4)

• 加拿大环境与气候变化中心(CMC)每日全球海表温度分析产品
• 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,本数据集还包含其他衍生数据集(如pCO₂、ISAR海表温度数据),这些数据将单独处理并拥有独立的元数据记录。
数据采样间隔为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(塔斯马尼亚州)的澳大利亚联邦科学与工业研究组织(CSIRO)海洋与大气(O&A)信息与数据中心(IDC)进行处理与归档。
本数据集提供以下时间间隔的数据:5秒间隔(NetCDF格式)、10秒间隔及5分钟间隔(ASCII格式)。有关本数据集的更多详细信息,请参阅本航次的航次总结报告及/或数据处理报告。
