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, methodologies and quality control procedures are described in Eriksen et al., 2020. The SOTS sub-facility publish Annual reports which include 'Sample' reports - which describe the 3 main types of samples and associated composition measurements, from shipboard sensor and sample measurements made during the service visits of the moorings. 1. Sediment trap samples collected by the Subantarctic Zone (SAZ) mooring. 2. Water samples collected by the RAS water sampler deployed on either the Pulse or Southern Ocean Flux Station (SOFS) mooring, and collected by the TM sampler deployed on the SOFS mooring. 3. Samples collected with other devices during the SOTS service voyages, e.g. from CTD Niskin bottles, in-situ pumps, continuous plankton recorders, and nets. Note that not all these sample types were collected in any given year. 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 settled in a 1000 ml measuring cylinder for 24 hours. The top 900ml is siphoned off once settled and the remainder is transferred into a 100ml measuring cyclinder and left to settle for 24 hours. Once settled the top 90 ml is siphoned off from these samples and the remainder is transfered into a sample jar. This is gently agitated and a 1ml sample is taken and transferred into a Segdwick rafter. The whole sample is ...
