Rapid Measurement of Phytoplankton Community Structure by Discrete Three-Dimensional Fluorescence Spectroscopy

Abstract

Abstract: The community structure of phytoplankton is one of the important indicators to evaluate the marine ecological
environment. At present, the research of this field is mainly based on the on-site sampling followed by laboratory analysis, lacking of rapid on-line automatic, {\sl in-situ} profile and remote sensing ground verification technology. In order
to meet the needs of rapid acquisition of phytoplankton community structure and ground verification
of remote sensing data, a fast field measurement method of marine algae community structure based
on discrete three-dimensional fluorescence spectrum was studied. Then an {\sl in-situ} online measurement
instrument of marine algae community structure was developed, and at last application demonstration
and comparative verification were carried out. The results show that the measurement technology
of marine algal community structure based on the discrete three-dimensional fluorescence
spectrometry can obtain the algal community structure and chlorophyll content quickly and
accurately. Compared with the existing technology, it has the advantages of fast, accurate,
stable and reliable measurement, and provides advanced technical means for the acquisition
of marine ecological environment monitoring data and ground verification of remote sensing data.

Key words: discrete three-dimensional fluorescence spectrum, algal community structure, rapid measurement technology, on-line measurement
