Nitrate Sensor V14

Nitrate sensors measure the nitrate concentrations in the ocean. Nitrogen is an essential element or nutrient in plant growth in the ocean, of which the dominant labile inorganic form is nitrate.  Nutrients typically have higher concentrations in the deep ocean, while concentrations near surface are often very low due to uptake by phytoplankton during photosynthesis.  The nitrate vertical gradient may be very dynamic, responding to both physical and biological processes.

During VISIONS '14, Nitrate sensors are planned for installation on the shallow water profilers at Axial Base (SF03A), Slope Base (SF01A), and at thre Endurance Array offshore site (SF01B)
