IMOS National Reference Station (NRS) - Sample Station Details

This dataset describes the sampling stations, which comprise part of a broader sampling program carried out by the Plankton National Reference Station within the Integrated Marine Observing system. 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 available freely via the AODN portal: https://portal.aodn.org.au. The main goals of the project are to: 1. Provide a record of physical, chemical and biological (plankton) changes in Australian coastal waters. 2. Record data as part of a larger comprehensive national dataset, comprising both continuous in-situ sampling and analysis of discrete physical, chemical and biological samples collected monthly. People using these data should also consider historical data available from three of the National Reference Station sites:Maria Island Coastal Station Data 1944-2008 ..

本数据集详细记录了采样站点的相关信息，这些站点隶属于综合海洋观测系统（Integrated Marine Observing System, IMOS）下属的浮游生物国家参考站（Plankton National Reference Station）所开展的大型采样计划的一部分。IMOS国家参考站野外采样站点共计9处，分别为：塔斯马尼亚州玛丽亚岛（Maria Island, TAS）、南澳大利亚州袋鼠岛（Kangaroo Island, SA）、埃斯佩兰斯（Esperance, WA）、罗特内斯特岛（Rottnest Island, WA）、宁加洛（Ningaloo, WA）、达尔文（Darwin, NT）、永格拉（Yongala, QLD）、北斯特拉德布罗克岛（North Stradbroke Island, QLD）以及哈克宁港100站位（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执行团队负责实施。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个站点的采样工作目前仍在持续。宁加洛与埃斯佩兰斯（西澳大利亚州）站点的采样工作已于2013年8月至9月间终止。
采样工作常规以月度为周期开展（埃斯佩兰斯与宁加洛站点为每3个月一次），依托小型船舶进行作业。采样水深范围随站点不同从表层至105米不等，通常以10米为间隔进行分层采样。
站点位置、采样水深及采集的样品类型等详细信息，可参见下文提取自《IMOS国家参考站生物地球化学作业实操手册（2.2版，2012年7月）》的PDF链接。本手册的完整链接也已同步提供，其中包含采样方案与分析流程的全部细节。
此外，作为澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）海岸监测计划的一部分，三处国家参考站站点已收录历史数据集：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家及国际项目的互操作性。站点元数据可通过该资源查询。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。
本项目的核心目标包括：
1. 记录澳大利亚沿海水域的物理、化学与生物（浮游生物）变化情况；
2. 将采集的数据纳入全国综合数据集体系，该体系包含连续原位采样以及按月开展的离散物理、化学与生物样品的采集与分析工作。
