Definition An instrument comprising conductivity, temperature, and pressure sensors, specifically designed for the Argo program. It is suitable for integration with profiling floats and can withstand air deployments. Derived channels for salinity, sound speed and density are built in. Atmospheric measurements can also be obtained and used to estimate sensor drift. The RBR argo3 CTD uses an inductive conductivity sensor, which does not require a pump and is accurate to within 10 cm of the air-ocean interface. The instrument's streamlined design minimises salinity spiking; it is built out of organic solderability preservative (OSP) and titanium. Features include a power consumption of approximately 24 mJ per sample, sampling rate of up to 8 Hz, and storage capacity of approximately 120 million readings. The depth rating can be configured to either 2000 dbar or 4000 dbar. A range of biogeochemical (BGC) sensors are available, including dissolved oxygen, fluorescence, PAR, and pH. Other specifications include: conductivity range between 0 and 85 mS/cm, accuracy of +/- 0.003 mS/cm, and resolution of 0.001 mS/cm; temperature range between -5 and 35 degC, accuracy of +/- 0.002 degC, and resolution of 0.00005 degC; depth accuracy of +/- 0.05% full scale, and resolution of 0.001% full scale.
