    abstract = {Mean concentrations of Dissolved Organic Carbon (DOC) and Particulate Organic Carbon (POC) were
in the ranges of 180-5390 and 1310-2610 μg/LC, respectively. Generally, higher concentrations of DOC and POC
were recorded in downstream areas as a result of inputs from anthropogenic activities. DOC was size
fractionated into high molecular weight (HMW, <100 kDa) and low molecular weight (LMW, <30 kDa). The
HMW DOC fraction generally dominated the total DOC. The HMW DOC dominance was associated with
agricultural, aquaculture and urban areas inputs. Resuspension of river sediment may also have played an
important role in controlling the HMW DOC distribution. The LMW DOC was significantly correlated with
chlorophyll-a (chl-a) suggesting processes related to phytoplankton may influence LMW DOC in the water
column. The DOC and POC concentrations were also influenced by climatological factors with high values
occurring during the monsoon season and lower values during non-monsoon season. In conclusion, the results
from this study aim to improve understanding of the dynamics of DOC and POC concentrations in the tropical
region.}
