Description 1005-1012
Twenty four water samples were collected and analyzed
for DOC and optical properties to characterize the origin

and fate of DOM (dissolved organic matter ) along the
land and coast continuum in the Sundarban mangrove of Bangladesh.
High levels of dissolved organic carbon (DOC) are associated with a highly
complex and aromatic character with SUVA254 of 7.13-45.05 L mg-C-1 m-1. Excitation-emission matrix (EEM) of DOM was analyzed
by the parallel factor analysis (PARAFAC); and three different
allochthonousfluorophore groups and one autochthonous fluorophore group were
identified. Intensive weathering coupled with anthropogenic activities in the
catchment area supplied a large amount ofvarying chemistry of allochthonous DOM
into the Sundarban mangrove. Emission wavelength bands at particular excitation
wavelength were used to estimate Fluorescence Index (FI, 1.38-1.74),
Biological/Autochthonous Index (BIX, 0.58-0.72) and Humification Index (HIX,
2.23-4.68), exemplify that fresh and labile DOM from terrestrial sources
regulate the carbon cycling in the Sundarban mangrove.
