Maintenance and Update Frequency: asNeeded Statement: Water samples are collected off small vessels at the IMOS National Reference Stations. The depth of the sample varies at each station. The sampling methods are fully described in the IMOS NRS Biogeochemical Operations Manual (Davies & Sommerville 2020). The analysis and quality control (QC) procedures (performed at CSIRO) are described in Eriksen et al. 2019. The SOTS data comes from the Southern Ocean Time Series project. The location is a fixed mooring with samples taken at various depths at regular intervals. 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 Marine and Atmospheric Research, 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 100 adult copepods and 500 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 exported to IMOS. ** All raw files and background information files can be accessed here - http://imos-data.s3-website-ap-southeast-2.amazonaws.com/?prefix=IMOS/BGC_DB/harvested_from_CSIRO/ ** Statement: For NRS stations only - Derived Indices Biomass This index includes the total mass of living organisms in sea water collected with a 100-micron mesh net. Thus, values provided by this parameter comprise the organic carbon from the plankton. Abundance Abundance is measured here as total number of elements (or individuals) for a specific taxon in sea water. This derived product is provided for phytoplankton (total number of cells), zooplankton and copepods (total number of animals). Mean total length of copepods This index provides the mean ...
