Deep SUNA Ocean Nitrate Sensor

Based on the proven MBARI-ISUS nitrate sensor, the Deep SUNA has been redesigned for easy integration with AUVs of all types. Deep SUNA provides real time, chemical-free nitrate calculations in deep ocean environments using Sea-Bird Scientific’s advanced UV absorption technology.

Deep SUNA features include:


• Full UV spectrum for maximum accuracy
• Real-time temperature/salinity compensation
• Real-time nitrate calculation
• Corrosion-proof anodized aluminum housing with 2000 meter depth rating
• Simple software-based, in-field reference checks
• User-friendly UCI software (Windows and Mac OS X compatible)


Note: The Deep SUNA is designed to be more aerodynamic than the SUNA V2 and its use on a AUV should not alter the speed significantly. The Deep SUNA sample rate is the same as the SUNA V2 @ – 1Hz.
