Novel dissolved nutrient sensors developed by the National Oceanography Centre’s (NOC’s) Ocean Technology and Engineering group were deployed on the Global Southern Ocean Surface Mooring from December 2018 to January 2020 in support of the CUSTARD(Carbon Uptake and Seasonal Traits in Antarctic Remineralisation Depth) project. This is the first autonomous sensor, suitable for the marine environment, capable of measuring in situ silicate and nitrate, key components of ocean biogeochemistry. The successful demonstration of these sensors to provide high quality nutrient measurements autonomously over an extended period of time will be exploited to generate interest in commercialization of the sensors.

Note: There are two datasets for this instrument: nocni and nocsi. Those data are found in their respective folders via the link below.
