资源简介:

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator Voyage IN2018_E03, titled: "Gear trials." The voyage took place between December 22 and December 23, 2018 departing from Hobart (TAS) and arriving in Hobart.This voyage was undertaken to test the beam trawl operation after a fix to the winch control system.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 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)“调查者号”远洋科考船(RV Investigator)航次IN2018_E03采集得到的走航观测数据(Underway, UWY),该航次标题为"设备调试试验"。 本次航次于2018年12月22日至23日开展,从塔斯马尼亚州霍巴特出发并最终返回霍巴特,旨在对绞车主控系统完成维修后,开展桁杆拖网作业的调试测试。 标准走航观测数据为连续记录,包含以下三类: (1) 导航数据(NAV):纬度、经度、航速、艏向、对地航向、陀螺罗经以及多普勒计程仪(双GPS型仪器); (2) 温盐深分析仪(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)以及光学溶氧传感器(Optode)/溶解氧数据; (3) 大气气象数据(MET):湿度、风速与风向(包含风标式和超声波型传感器)、辐射计/海表温度、总辐射表/太阳辐射、光合有效辐射(PAR)、气温、气压、降水、臭氧以及痕量气体(左舷与右舷观测仪器)。 经质量控制的“调查者号”科考船走航气象与海表温度(Sea Surface Temperature, SST)数据会被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"机会航船"项目的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。美国国家海洋和大气管理局(NOAA)会从该服务器下载数据至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型海表温度传感器数据会被澳大利亚气象局用于实时卫星海表温度验证工作,并被纳入实时海表温度分析产品,该产品随后将作为数值天气预报(Numerical Weather Prediction, NWP)模式的边界条件。上述气象与海表温度数据会被上传至全球电信系统(Global Telecommunications System, GTS),以供向全球气象机构进行广播分发;同时数据也会单独提交至SAMOS项目(http://samos.coaps.fsu.edu/html/),用于海气通量相关科研工作。 当前(2017年),实时SBE 38型海表温度数据会被应用于以下公开数据产品(可通过全球电信系统GTS获取): • 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扩展重构海表温度数据集第4版(NOAA NCEI ERSST.v4)(https://www.ncdc.noaa.gov/data-access/marineocean-data/extended-reconstructed-sea-surface-temperature-ersst-v4) • 哈德利中心海表温度数据集(HadSST3)(http://www.metoffice.gov.uk/hadobs/hadsst3/) • 全球海洋走航表面数据(GOSUD)项目(http://www.gosud.org/) • 澳大利亚气象局每日/周海表温度分析产品(http://www.bom.gov.au/marine/sst.shtml) • 美国国家海洋和大气管理局国家环境信息中心"Reynolds"每日全球最优插值海表温度(OISST)分析产品(https://www.ncdc.noaa.gov/oisst) • 美国国家航空航天局喷气推进实验室(NASA JPL)"MUR"1公里分辨率每日全球海表温度分析产品(https://mur.jpl.nasa.gov/) • 英国气象局"OSTIA"每日全球海表温度分析产品(http://ghrsst-pp.metoffice.com/pages/latest_analysis/ostia.html) • 加拿大环境与气候变化部(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,本项目还生成了其他数据集(如pCO₂、ISAR海表温度数据),这些数据集会单独进行处理,并拥有独立的元数据记录。 数据以5秒的间隔进行记录。近实时数据可通过"走航数据可视化工具"链接获取。本数据集将由位于塔斯马尼亚州霍巴特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)。关于本数据集的更多详细信息,可查阅本次航次的航次总结报告和/或数据处理报告。
