Estimation of DOC reservoir in East China Sea using satellite remote sensing
DOC,the largest organic carbon pool in the ocean,plays an essential role in the global carbon cycle.The estimation of DOC reservoir of the ocean can give us a better understanding of organic carbon cycle and help to estimate the carbon fluxes and carbon budget.By far the studies on the estimation of DOC reservoir are still sparse due to the lack of sufficient in-situ data; the satellite remote sensing has unique advantages in acquiring distribution of ocean color parameters.In this paper,based on the analysis of mechanisms of DOC vertical distribution,the vertical profiles of DOC in the East China Sea in four seasons except summer have been classified into two typical types,one is uniform profile and the other is T-type profile which can be segmented into three sections.And the vertical distribution model of DOC has been proposed on the basis of in-situ data.The surface DOC distribution can be derived from satellite remote sensing colored dissolved organic matter product by using the empirical algorithm.Finally,the DOC reservoirs in the water column are estimated by integrating the vertical model and surface concentration of DOC.The results shows that the satellite remote sensing results of DOC reservoirs are consistent with the in-situ calculation,the differences between the two sets of data are below 8% in all three seasons.
