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).

The 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.

The 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.

本数据集包含经预处理的抛弃式温深计（Expendable Bathythermograph, XBT）数据，采集自澳大利亚海洋国家设施（Marine National Facility, MNF）旗下的RV富兰克林号与RV南方考察者号科考船。XBT数据通常由探针穿过海洋表层数百米范围时，以每0.1秒的间隔向海面传回的温度与深度读数组成。本数据集已由澳大利亚联邦科学与工业研究组织（CSIRO）海洋与大气部（原CSIRO海洋与大气研究中心）的海洋观测网络（Ocean Observing Networks, OON）团队完成质量控制。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海洋学数据中心（National Oceanographic Data Center, NODC）全球温度-盐度剖面计划（Global Temperature-Salinity Profile Program, GTSPP）获取（其中RV富兰克林号的平台代码为09FA，呼号为VJJF；RV南方考察者号的平台代码为09SS，呼号为VLHJ），同时也可在澳大利亚海洋数据网络（Australian Ocean Data Network, AODN）获取。
针对MARVL项目提取的数据子集，其范围为基于2012年水深数据集所划定的200米等深线大陆架区域，并与澳大利亚海事边界数据集中的专属经济区（Exclusive Economic Zone, EEZ）进行空间合并（空间并集）所得。该2012年水深数据集可从澳大利亚地球科学局（Geosciences Australia, GA）获取，链接为http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_63565。该数据子集包含来自15个航次的47条XBT测站记录，涵盖温度、压力以及衍生盐度数据，时间跨度为1995年至今。
完整数据集存储于海洋与大气部信息与数据中心数据仓库，目前馆藏有自1985年以来72余次航次所采集的724条以上XBT测站记录。
