Continuous monitoring of nutrient levels, nitrogen and phosphorus, provides crucial information about daily, seasonal and event-based changes in water quality conditions, and can be a strong indicator on the overall health of the water body.
Under certain conditions, such as warm, sunny weather and slow-moving water, elevated nutrient concentrations can promote the growth of nuisance phytoplankton causing algal blooms (eutrophication) which can dramatically affect aquatic ecology, and in extreme cases, prevent photosynthesis. Algae, and the bacteria that feed on decaying algae, produce toxins. In combination, these two effects can lower dissolved oxygen levels, killing fish and other organisms. Harmful algal blooms (HABs) therefore represent a major threat to water resources.
OTT HydroMet offers several solutions for long-term unattended measurement of nitrate and phosphate in real-time, while HYDROLAB multiparameter sondes have several sensor options for nutrient measurement as well.
Stay on top of the issue by discovering current and future trends of nutrient monitoring.

Nutrient Monitoring in Foreman Branch in Support of the Chester River Watershed Observatory
The Chester River Watershed Observatory (CRWO), Washington College, Sea-Bird Scientific and OTT HydroMet have developed a real-time nutrient and water quality monitoring platform to evaluate the use of direct water monitoring in collaboration with a working farm. Read about how watershed water quality can now be supported by direct in-situ nutrient and water quality measurements.
Nutrient Monitoring in Northern Florida
In the karst springs of northern Florida, nutrient monitoring was utilized to deliver real-time nitrate and phosphate analysis for ecosystem modeling. Learn how the Satlantic SUNA and WET Labs Cycle-PO4 have opened up new avenues for understanding how river ecosystems process nutrients.
Measuring Nitrate in Puget Sound Using Optical Sensors
In this case study, the SUNA nitrate sensor performed as a robust tool to measure nitrate concentrations in oceanic and freshwater environments. Learn how this team used the appropriate calibrations and corrections to conduct long-term marine monitoring to assess baseline conditions and trends in Central Puget Sound.
