Instrumentation
Platform 1 focuses on marine meteorology and delivers measurements which are necessary for computing air-sea fluxes of heat, momentum and mass with the option to measure surface photosynthetically active radiation and surface UV to help assess light available for phytoplankton production.
Platform 2 is the ACE/CMAR PULSE mooring design currently deployed at the Sub-Antarctic site and it will be tasked with observing the ocean carbon cycle and phytoplankton productivity. Its capability will be enhanced to enable collection of a wider range of parameters to assess biogeochemical and carbon cycling. See a brief history of Pulse (pdf).
Platform 3 is a Tethered Profiler based on the APEX float that measures high resolution vertical profiles of ocean temperature, salinity, fluorescence, turbidity; and oxygen. Data is delivered in real-time using Iridium communications.
Platform 4 is a deep sea glider. It will make the same measurements as the profiling float with the advantage of also providing mesoscale context for the Pulse mooring. For more info on gliders go to ANFOG.
Platform 5 is the SAZ deep sediment trap mooring deployed at the site with annual turn-around since 1997. The mooring has current meters and sediment traps at 1000 and 2000m. These will provide estimates of advective transports and sinking particle carbon transports that complement and extend the surface observations proposed here
