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 .. MarLIN Record Number: 4849
Port Hacking 100m Coastal Station Data 1953-2010 .. MarLIN Record Number: 5301
Rottnest Island Coastal Station Data 1951-2009 .. MarLIN Record Number: 4877

Statement: Data sampling is being conducted as part of a larger IMOS monitoring program. The zooplankton samples are analysed at the Plankton Ecology Lab at CSIRO O&A, Dutton Park, Queensland. The samples are concentrated down to 100 ml in a measuring cylinder. A subsample (1 ml, 2.5 ml or 5 ml) is taken from the 100 ml concentrate using a stempel pipette. The sub sample is analysed to the lowest taxa possible. For each sample 50 adult copepods and 250 total zooplanktons must be counted. If these conditions are not met by the first sub sample analysis, a second sub sample is analysed. This continues until the two conditions are met. These counts are then converted to taxa / m3 and the analysis data is available through AODN portal: https://portal.aodn.org.au.
These data are from the National Mooring Network, part of the Integrated Marine Observing System (IMOS) - IMOS is a national collaborative research infrastructure, supported by the Australian Government.
Each NRS collects its own zooplankton samples and sends them to the CSIRO O&A Dutton Park laboratories for analysis.
Operation of the National Reference Station (NRS) sampling and analyses is provided by the IMOS NRS Biogeochemical (BGC) project and is distributed between several operators and is coordinated nationally.
