O&A ADCP MARVL Data

The O&A Acoustic Doppler Current Profiler (ADCP) data set includes data collected during the voyages of Australia's Marine National Facility, and of various CSIRO marine research vessels. ADCP data consists of vertical current profiles binned at depth intervals of between 2 to 16 metres.\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 77,693 ADCP profile records from 155 voyages and includes corrected U and V values at a centred binned depth 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 387,181 ADCP profile records from more than 222 voyages collected since 1987. This data includes corrected U and V values at a centred binned depth. Individual metadata records have been created for each research voyage.

O&A声学多普勒海流剖面仪（Acoustic Doppler Current Profiler，ADCP）数据集收录了澳大利亚海洋国家设施航次及澳大利亚联邦科学与工业研究组织（CSIRO）多艘海洋科考船采集的观测数据。ADCP数据以2至16米的深度间隔分层，包含垂向海流剖面数据。

为MARVL项目提取的数据集子集，涵盖由2012年水深数据集划定的200米等深线所界定的大陆架区域，且该区域已与澳大利亚海洋边界数据集（可从澳大利亚地球科学局[GA]获取，链接：http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_63565）内的专属经济区（Exclusive Economic Zone，EEZ）完成空间合并（spatial union）。该子集共包含155个航次的77,693条ADCP剖面记录，包含以分层中心深度为基准的校正后U、V流速分量，观测时段覆盖1995年至今。

完整数据集存储于O&A信息与数据中心数据仓库，目前该仓库收录了自1987年以来222余个航次的387,181条ADCP剖面记录。该数据集包含以分层中心深度为基准的校正后U、V流速分量。每个科考航次均已创建独立的元数据记录。
