Discussion on some questions in the studies on CDOM light absorption

HAN Yu-chao,GUO Wei-dong, CHENG Yuan-yue(Department of Oceanography, Xiamen University, Xiamen 361005, China)  
Based on the field investigation and laboratory experiment for CDOM(chromophoric dissolved organic matter) in seawater from Xiamen Bay, some issues in the current CDOM studies were discussed, including blank subtraction, estimation of spectral absorption coefficient and exponential slope coefficient(S) and the effects of different filter membrane on CDOM optical properties.How to identify a theoretical conservative mixing line of S during estuarine mixing process was also explained.In order to eliminate any artifacts on the absorbance spectra of water samples, pre-filtered(0.2μm) purified water was used as a blank. Absorption coefficients should be corrected for the influence of non-CDOM signals. For both seawater and river water samples, the linear regression technique gave consistently lower estimates of S compared with nonlinear regression technique over the same wavelength ranges. When estimated over the different wavelength ranges, S vales decreased as the components of longer wavelengths increased in the wavelength range, especially using the linear regression technique. On the whole, the difference in wavelength range did not prominently influence the S values when estimated by the non-linear regression technique. In this paper, S values were derived from the non-linear regression of the corrected absorption coefficients against wavelength from 300500 nm. It is not only the initial S values of CDOM from river water and seawater endmembers, but also the relative magnitude of CDOM concentration in each endmember that determine how S will behave during estuarine mixing. The influence of the difference of the filter pore size on the absorbance spectra can not be neglected in the coastal Case water and 0.2μm filter was recommended.
