Attached to this record are the originally supplied datasets for 1997-1998, and also summary files and mooring diagrams supplied in 2012. Taken from the 2008-2009 Progress Report: Progress against objectives: The key to advancing the objective of understanding ocean processes controlling uptake of atmospheric CO2 is the ability to deploy moored autonomous samplers and sensors in Southern Ocean surface waters capable of quantifying seasonal cycles in biological and biogeochemical processes. Our effort in the last 12 months has focused on development of a robust mooring platform to carry these devices. We deployed two different engineering test designs, known as Pulse 5 Heavy and Pulse 5 Light. Both designs survived 6 months in the sea, including wave heights up to 12 meters, while transmitting mooring tensions, mooring accelerations, and GPS positions live to the internet (www.imos.org.au). Following this success we are preparing to deploy the next version of Pulse with scientific instruments to measure temperature, salinity, oxygen, and phytoplankton fluorescence. In addition we deployed a deep ocean mooring with time-series sediment traps to quantify sinking particle fluxes, and in-situ settling columns to determine particle sinking rates. Taken from the 2009/2010 Progress Report: Progress against objectives: Two voyages were awarded by the Australian Marine National Facility to use RV Southern Surveyor to service these Southern Ocean Time Series (SOTS) moorings in the 2009/10 season, and for this reason the shiptime awarded to this project by AAS was not needed and was relinquished. This arrangement will continue in 2010/11 for which the MNF has again awarded two voyages in September 2010 and April 2011. The fieldwork in 2009/10 was very successful: i) the SAZ deep sediment trap mooring was recovered in September 2009 and redeployed for recovery in September 2010. ii) the PULSE biogeochemistry mooring was deployed in September 2009 and functioned beautifully prior to recovery in March 2010 for servicing. It will be redeployed in September 2010. iii) the SOFS Southern Ocean Flux Station mooring was completed and deployed in March 2010 for recovery in April 2011, and redeployment in September 2011.
