O&A XBT MARVL Data

This dataset contains the processed Expendable Bathythermograph (XBT) data collected on Australia's Marine National Facility (MNF) RV Franklin and RV Southern Surveyor. XBT data typically comprises temperature and depth readings relayed to the surface at intervals of 0.1 seconds as the probe passes through the top few hundred metres of the ocean. This dataset has been QCed by the CSIRO Oceans & Atmosphere's (Formerly CSIRO Marine and Atmospheric Research) Ocean Observing Networks (OON) group. The data can be retrieved via CMAR Data Trawler, please see link below. The data is also available via the international National Oceanographic Data Center (NODC) Global Temperature-Salinity Profile Program (GTSPP) (Franklin platform code: 09FA and call sign: VJJF, Southern Surveyor platform code: 09SS and call sign: VLHJ) and Australian Ocean Data Network (AODN).\n\nThe subset extracted for MARVL contains data on the continental shelf as defined by the 200 metre depth contour from the 2012 Bathymetric dataset merged (spatial union) with the Exclusive Economic Zone (EEZ) in the Australian Maritime Boundary dataset (http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_63565) available from Geosciences Australia (GA). This subset of the data contains 47 XBT station records from 15 voyages and includes temperature, pressure and salinity (derived) and spans from 1995 to the present. \n\nThe full data set is held in the O&A Information & Datacentre Data Warehouse, which currently holds over 724 XBT station records from more than 72 surveys collected since 1985.

本数据集包含经处理的抛弃式温深计（Expendable Bathythermograph，XBT）观测数据，采集自澳大利亚海洋国家设施（Marine National Facility，MNF）的“富兰克林号”（RV Franklin）与“南方考察者号”（RV Southern Surveyor）两艘研究调查船。抛弃式温深计数据通常在探头穿过海洋表层数百米水域时，以每0.1秒的间隔向水面传回温度与深度读数。本数据集已由澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气研究所（原海洋与大气研究中心）下属的海洋观测网络组（Ocean Observing Networks，OON）完成质量控制。用户可通过CMAR数据拖网工具（CMAR Data Trawler）获取该数据，具体链接见下文。此外，该数据还可通过国际国家海洋数据中心（National Oceanographic Data Center，NODC）的全球温盐剖面计划（Global Temperature-Salinity Profile Program，GTSPP）以及澳大利亚海洋数据网络（Australian Ocean Data Network，AODN）获取：其中“富兰克林号”的平台代码为09FA，呼号为VJJF；“南方考察者号”的平台代码为09SS，呼号为VLHJ。

本数据集为MARVL提取的子集，其范围为2012年水深数据集与澳大利亚地球科学局（Geosciences Australia，GA）公开的澳大利亚海洋边界数据集内的专属经济区（Exclusive Economic Zone，EEZ）进行空间合并后，以200米等深线划定的大陆架区域。该子集包含15个航次的47个XBT测站记录，涵盖温度、压力及衍生盐度数据，时间跨度为1995年至今。

完整数据集存储于海洋与大气研究所信息与数据中心数据仓库，目前馆藏了自1985年以来72个航次采集的共计724条以上XBT测站记录。
