Our preliminary plans and operating areas for deployment are described in the table below. Research ships are required for optimal deployment of these floats because of the requirement for in situ calibration of the suite of chemical sensors by measurements using water samples and CTD profiles. This is different from the traditional Argo floats, which do not require in situ calibration. Research ship float deployment cruises, with country and international collaborator where applicable. Remaining floats to be deployed as needed from other cruises of opportunity.

Year 1 Drake Passage (10 floats): Stanley, Falkland Islands (UK NOC; Brian King). NOC CTD measurements and rosette sampler. ODF, Dickson chemistry.
Year 2 Central Indian Ocean (~40 floats): Capetown, South Africa (U.S. UNOLS vessel request). ODF CTD and ODF/Dickson chemistry.
Year 3 Eastern South Atlantic and Africa south to Antarctica (~40 floats): Capetown, South Africa (South Africa UCT; Isabelle Ansorge).
Year 4 Australian region south to Antarctica (Australia CSIRO; Steve Rintoul) (~30 floats): Hobart, Tasmania. CSIRO will make all necessary measurements.
Year 5 Central South Pacific south to Ross Sea (U.S. UNOLS vessel request) (~40 floats). ODF CTD and ODF/Dickson chemistry.


Note: NOC is the National Oceanographic Centre in Southampton, UK; CTD is conductivity, temperature, and depth; ODF is the Scripps Institution of Oceanography’s (SIO) Oceanographic Data Facility; Dickson chemistry is carbon system measurements made by A. Dickson at SIO; UCT is the University of Capetown, South Africa.
