Abstract:

       Nutrients are necessary substance basis for the growth of marine phytoplankton. Determining their marine distributions has significant meanings in understanding global geochemical cycles and forecasting the occurrence of HABs (Harmful algal blooms). Online nutrient sensors have been greatly improved during the past decades. This paper surveys their research advances in marine monitoring, introduces and compares their detection principles, ranges and limits, and presents their technical bottlenecks and development tendency.

Key words: nutrient, sensor, marine monitoring
