Particulate organic carbon （POC） is of significance in ocean carbon cycling and adiusting to the climate changes influenced by the increased C02. Remote sensing technology is an important way to acquire POC information of seawater. As a consequence, remote sensing capable of monitoring large scale and real-time POC has become an important issue in the field of ocean studies. This paper comprehensively summarizes the remote sensing inversion algorithm of ocean POC at home and abroad, including remote sensing inversion of POC at the surface layer and in vertical direction of case Ⅰ and case Ⅱ water bodies, as well as the classification, comparison and analysis of accesses for POC remote sensing. Meanwhile, in this paper, remote sensing inversion of POC in sea is expected and it is proposed to combine surface and vertical distribution of POC to build a three-dimensional remote sensing model for POC at offshore areas.
