Deployment of the moorings has varied with time, with the SAZ mooring deployed for the first time in 1998. The biogeochemical Pulse moorings had several deployments that were used for development (2007 to 2011). In 2011 a duplicate mooring was built to enable at-sea turn-arounds. The Pulse moorings are swapped over on roughly an annual basis, depending on ship availability. The Southern Ocean Air Sea Flux mooring was deployed in 2010, with a duplicate flux mooring deployed for the first time as SOFS-3 in July 2012. This allowed for a continuous record of flux measurements at the site. The air sea flux mooring is swapped over on a roughly annual basis.

Each of the moorings required some development to overcome engineering and technical requirements for operating consistently in the high seas, strong current and severe storms that dominate the sub-Antarctic Zone.

Between 2010 and 2011 iRobot ocean gliders were deployed at the Southern Ocean Time Series site to traverse a line from the Southern Ocean Time Series site back to the Tasmanian coast.  The glider deployed in March 2010 successfully completed its mission after being recovered in June 2010 but a second deployment in April 2011 had some technical issues. The glider work is now on hold until methods are developed to ensure that they work successfully when deployed from the Southern Ocean Time Series site.
