Southern Ocean Observing System (SOOS) is an international initiative of the Scientific Committee on Antarctic Research (SCAR) and the Scientific Committee on Oceanic Research (SCOR).

[1] Its International Project Office is hosted by the Institute for Marine and Antarctic Studies (IMAS), University of Tasmania, Australia.

Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem.

[3] SOOS is designed to aid the collection and delivery of essential observations on dynamics and change of Southern Ocean systems to all international stakeholders (researchers, governments, industries).

It seeks to enable the design, advocacy and implementation of cost-effective observing and data delivery systems.
