IMOS National Reference Station (NRS) - IMOS Data Quality Control Flags

This dataset describes the Data Quality Control Flags and Descriptions used by the Integrated Marine Observing System (IMOS) National Reference Station sampling sites.Nine Sites are included in the IMOS NRS field sampling stations. Maria Island (TAS), Kangaroo Island (SA), Esperance (WA), Rottnest Island (WA), Ningaloo (WA), Darwin (NT), Yongala (QLD), North Stradbroke Island (QLD) and Port Hacking 100 (NSW). Sampling at these sites is conducted by several members of IMOS NRS Biogeochemical project. Sampling at the sites began between 29/9/2008 and 8/11/2010 and is currently ongoing for 7 sites. Sampling ceased at Ningaloo and Esperance (WA) sites in Aug/Sept 2013.Sampling is conducted monthly (Esperance and Ningaloo were 3 monthly) off small vessels. Depths sampled range from surface to 105 metres depending on the site. Depths are usually sampled at 10 metre intervals. Details including information on station locations, depths sampled and sample types collected are shown in the PDF link below extracted from the IMOS NRS NATIONAL REFERENCE STATIONS BIOGEOCHEMICAL OPERATIONS - A PRACTICAL HANDBOOK, Version 2.2 July 2012. A link to the full handbook is also provided which includes full details of the sampling regime and analyses.Historical data collected as part of CSIRO Coastal Monitoring program is available for three of the National Reference Station sites:Maria Island Coastal Station Data 1944-2008, Port Hacking 100m Coastal Station Data 1953-2010 and Rottnest Island Coastal Station Data 1951-2009.The links to the metadata and access for these data is provided below.Data storage and access is planned to be interoperable with other national and international programs through the IMOS Infrastructure. Station metadata can be found through this resource. Data is freely available through the AODN portal: https://portal.aodn.org.au

本数据集详述了综合海洋观测系统（Integrated Marine Observing System, IMOS）国家参考站采样站点所使用的数据质量控制标记（Data Quality Control Flags）及其说明。IMOS国家参考站野外采样站点共计9处，分别为塔斯马尼亚州的玛丽亚岛（Maria Island, TAS）、南澳大利亚州的袋鼠岛（Kangaroo Island, SA）、西澳大利亚州的埃斯佩兰斯（Esperance, WA）、罗特内斯特岛（Rottnest Island, WA）、宁加卢（Ningaloo, WA）、北领地的达尔文（Darwin, NT）、昆士兰州的扬古拉（Yongala, QLD）、北斯特拉德布罗克岛（North Stradbroke Island, QLD）以及新南威尔士州的哈克宁港100（Port Hacking 100, NSW）。

上述站点的采样工作由IMOS国家参考站生物地球化学项目的多个参与方共同开展。各站点的采样启动时间介于2008年9月29日至2010年11月8日之间，其中7处站点目前仍在持续进行采样；宁加卢与埃斯佩兰斯（西澳大利亚州）站点的采样工作已于2013年8-9月终止。

常规采样频次为每月1次，埃斯佩兰斯与宁加卢站点曾采用每3个月1次的采样频率，所有采样作业均通过小型近海船舶完成。采样水深范围随站点差异从表层至105米不等，通常以10米为间隔进行分层采样。

站点位置、采样水深及采集样品类型等详细信息，可参见下述提取自《IMOS国家参考站生物地球化学作业实用手册（2012年7月第2.2版）》的PDF链接。本数据集同时提供完整手册的链接，其中包含采样方案与分析流程的全部细节。

作为澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）海岸监测项目的组成部分，三处国家参考站站点拥有公开历史数据集：玛丽亚岛海岸站数据（1944-2008年）、哈克宁港100米海岸站数据（1953-2010年）以及罗特内斯特岛海岸站数据（1951-2009年）。上述数据的元数据与获取链接已在下方提供。

本数据集的存储与访问将通过IMOS基础设施实现与其他国内外相关项目的互操作性。站点元数据可通过本资源获取，所有数据均可通过澳大利亚海洋数据网络（Australian Ocean Data Network, AODN）门户免费获取：https://portal.aodn.org.au
