Abstract:

In this paper, the transport of suspended matter in the surface of the Yellow Sea and the East Sea was analyzed through the fourth band reflectivity of the Moderate Resolution Imaging Spectroradiometer (MODIS) from 2002 to 2015. In the meantime, the in situ data of suspended matter content in the Yellow Sea and the East Sea in 2003 as well as the quasi-real time MODIS image data during this period were utilized to establish a remote sensing inversion model of suspended matter content based on MODIS fourth band remote sensing reflectivity. Using this model, the concentration of suspended matter in the surface layer of the Yellow Sea and the East China Sea was reversed, and the diffusion area of suspended matter was calculated. Then, according to the surface suspended matter concentration obtained from the inversion model and the suspended matter concentration of vertical prediction model, the suspended matter in the vertical direction was estimated. Meanwhile, the suspended matter content in the water at a specific time was calculated by taking into account of water depth and diffusion area. Next, the suspended matter content in the water at various moments during the transport was figured out using cubic polynomial interpolation, from which the transport amount at various moments was derived. The estimated transport amount of suspended matter from the Yellow Sea to the East Sea from October 2002 to April 2003 was 0.153 billion tons.
