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 quality controlled datasets are publicly available via the AODN Data Portal. This report should be consulted when using the data. The Southern Ocean Time Series (SOTS) Observatory located at 140°E and 47°S provides high temporal resolution observations in sub-Antarctic waters. It is focused on the sub-Antarctic Zone because waters formed at the surface in this region slide under warmer subtropical and tropical waters, carrying CO2 and heat into the deep ocean, where it is out of contact with the atmosphere. This process also supplies oxygen for deep ocean ecosystems, and exports nutrients that fuel ~70% of global ocean primary production. This region is also the boundary between the nutrient rich waters of the Southern Ocean and the oligotrophic subtropical gyres to the north. These processes are sensitive to climate change, but the probable nature and impacts are not yet known.
