IMOS National Reference Station (NRS) - Total Suspended Solids (TSS) and Secchi Depth

This dataset comprises the measurement of Secchi Depth and Total suspended solids (inorganic and organic components) analysed from samples collected as part of the Integrated Marine Observing Systems (IMOS) National Mooring Network -National Reference Station (NRS) field sampling. 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. Details including information on station locations, depths sampled, sample regime, sample types collected, and analyses can be found in the “IMOS National Reference Stations Biogeochemical Operations Manual” (see link below to latest version, plus link to previous versions and supplementary documentation). 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. **This dataset has been superseded by the "IMOS - Combined Biogeochemical parameters (reference stations)" collection that is available at https://catalogue-imos.aodn.org.au/geonetwork/srv/api/records/b442c3e8-3d30-48ad-b144-680afd848167 (this collection was removed from the AODN Portal in February 2022).**

本数据集涵盖了基于综合海洋观测系统（Integrated Marine Observing Systems）国家锚定网络-国家参考站（National Reference Station）野外采样所收集的样本，所分析得到的赛氏盘透明度（Secchi Depth）与总悬浮固体（Total suspended solids，包含无机与有机组分）的测量数据。IMOS国家参考站野外采样站点共包含9个站位，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）、西澳大利亚州埃斯佩兰斯（Esperance, WA）、西澳大利亚州罗特内斯特岛（Rottnest Island, WA）、西澳大利亚州宁加卢（Ningaloo, WA）、北领地达尔文（Darwin, NT）、昆士兰州扬格拉（Yongala, QLD）、昆士兰州北斯特拉德布罗克岛（North Stradbroke Island, QLD）以及新南威尔士州哈克角100号站位（Port Hacking 100, NSW）。

IMOS国家参考站生物地球化学项目的多个参与方负责上述站点的采样工作。各站点的采样工作启动于2008年9月29日至2010年11月8日之间，其中7个站点的采样目前仍在持续；西澳大利亚州的宁加卢与埃斯佩兰斯站点的采样已于2013年8月至9月间停止。采样工作通常以月度为周期开展，埃斯佩兰斯与宁加卢站点曾为每季度一次，所有采样均通过小型船舶完成。

站点位置、采样水深、采样方案、采集的样本类型以及分析方法等详细信息可查阅《IMOS国家参考站生物地球化学作业手册》（最新版本链接及历史版本、补充文档链接见下文）。

另有三项由澳大利亚联邦科学与工业研究组织（CSIRO）海岸监测计划所收集的历史数据，面向其中3个国家参考站站点开放：玛丽亚岛海岸站数据（1944-2008年）、哈克角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）。这些数据的元数据及获取链接见下文。

本数据集计划通过IMOS基础设施实现与其他国家及国际项目的数据存储与访问互操作性，站点元数据可通过该资源获取。

**本数据集已被可在https://catalogue-imos.aodn.org.au/geonetwork/srv/api/records/b442c3e8-3d30-48ad-b144-680afd848167获取的“IMOS-组合生物地球化学参数（国家参考站）”数据集所替代（该数据集已于2022年2月从AODN门户网站下架）。**
