Maintenance and Update Frequency: asNeeded Credit Australia's Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent.

The moorings are 1) the Pulse biogeochemistry mooring (instrumentation was moved to the FluxPulse mooring in 2016, and then to the SOFS mooring); 2) the Sub-Antarctic Zone (SAZ) sediment trap mooring; and 3) the Southern Ocean Flux Station (SOFS) (the instrumentation was briefly moved to the FluxPulse mooring in 2016). All three are operated by the Australian Bluewater Observing System. Data are processed in delayed mode and available in NetCDF format. The Southern Ocean Time Series (SOTS) sub-facility provides high temporal resolution observations in sub-Antarctic waters. Observations are broad and include measurements of physical, chemical and biogeochemical parameters from multiple deep-water moorings. The emphasis is on inter-annual variations of upper ocean properties and their influence on exchange with the deep ocean. The time-series provided permit investigation into issues of ocean physics and chemistry, climate change, carbon cycling and biogeochemical controls on marine productivity. The Pulse biogeochemistry mooring is used to measure upper ocean carbon cycle and phytoplankton productivity processes. Measured parameters include temperature, salinity, dissolved oxygen, nitrate, clorophyll and turbidity. This mooring also collects water samples ...
