Rottnest Island Coastal Station Data 1951-2009

This dataset contains a time-series of oceanographic data collected at the 50m coastal station off Rottnest Island, Western Australia (lat. 32 deg. 00 min. S, long. 115 deg. 25 min. E). The station was set up under the CSIRO coastal monitoring programme in the 1950s and is sampled for temperature, salinity, dissolved oxygen, nitrate and silicate at depths of 0, 10, 20, 30, 40 and 50m below the surface. Sampling is undertaken at monthly intervals from April 1951 and continued until July 2002, after which the sampling regime was irregular. The data are stored on-line as part of the CMR hydrology archive in Hobart and are available via the CMAR Data Trawler see link below. Since April 2009 the sampling became part of the IMOS program. The current sampling regime is approximately monthly for 11 or 12 months per year. The IMOS sampling includes additional Biological data. The ongoing data is currently available via the IMOS portal. Please see Data Links below.

Additional copies of the data up to 1989 are deposited with the NODC data archive (World Data Centre-A) in the U.S.A., and details of relevant data files can be viewed via their website by requesting the file inventory for this coastal station which is NODC platform code "09K2". Station details, plus printed versions of the data up to the end of 1960, have been published in CSIRO's "Oceanographical Station List" series.

本数据集包含采集于澳大利亚西部罗特内斯特岛外50米近海站位的海洋时间序列数据，该站位地理坐标为南纬32°00′、东经115°25′。该站位始建于20世纪50年代，隶属于联邦科学与工业研究组织（CSIRO）海岸监测计划，采样指标涵盖水温、盐度、溶解氧、硝酸盐及硅酸盐，采样深度设置为海面下0、10、20、30、40及50米。采样工作自1951年4月起以月度为间隔开展，持续至2002年7月，此后采样制度转为不定期。原始数据作为霍巴特CMR水文档案库的组成部分在线存储，可通过CMAR数据拖网（CMAR Data Trawler）获取，具体链接详见下文。2009年4月起，该站位的采样工作纳入综合海洋观测系统（IMOS）计划。当前采样模式为每年开展11至12个月的近似月度采样，且IMOS采样新增了生物相关观测数据。目前续测数据可通过IMOS门户网站获取，具体链接详见下文。
1989年之前的数据集副本已存档于美国国家海洋数据中心（NODC）下属的世界数据中心A（World Data Centre-A），相关数据文件的详细信息可通过其官网查询，需申请获取该近海站位的文件目录，该站位的NODC平台代码为“09K2”。此外，该站位的基础信息及1960年底前的纸质版数据已刊载于CSIRO的《海洋站名录（Oceanographical Station List）》系列出版物中。
