Introduction
With the continuous development of ocean optics survey technology, the spectral absorption coefficients of particulate matter and yellow matter in seawater have become ocean optics.
One of the widely measured parameters in the investigation. In-depth understanding of the spectral absorption characteristics of particulate matter and yellow matter in seawater is not only a quantitative measurement of ocean optical remote sensing
The basis of chemical application also helps us to have a deeper understanding of the bio-optical model, the characteristics of radiation from water and the law of radiation transmission in water.
At present, many domestic units use spectrophotometry to measure the spectral absorption coefficient of particulate matter and yellow matter in seawater, and they have also obtained a large number of treasures.
Expensive marine test data, but because there is no domestic measurement standard for this method, different units do not have a unified measurement method, and a large amount of data cannot
Sharing has caused a waste of resources. Develop industry standards for the measurement method of the spectral absorption coefficient of particulate matter and yellow matter in seawater to clearly measure
Measure scope and objects, standardize measurement procedures and methods, improve measurement level and quality, and share measurement data.
