Research progress on factors influencing the marine application of chlorophyll sensors

Chlorophyll concentration is an important index in the measurement of marine phytoplankton abundance. Rapid and accurate determination of chlorophyll content in seawater is crucial to operational monitoring and scientific research. Chlorophyll sensors based on in-vivo fluorescence method is easy to use, which not only can be in situ monitored for a long time, but can easily obtain huge amounts of measured data and can become the main development trend of high-precision measurement of seawater chlorophyll. However, the influence of various environmental factors causes a large deviation between the chlorophyll sensor data and the laboratory extraction method.This work provides a comprehensive review of studies on the influence of marine environmental factors, such as turbidity, light, temperature, salinity and algal physiological factors on chlorophyll sensor measurement, along with the influencing mechanism and data correction methods. Moreover, research ideas regarding quality control method of in vivo fluorescence-based chlorophyll sensor data quality control method are proposed.
