Abstract

Abstract:

We investigate the spatial distributions of transparent exopolymer particles (TEP) in the Pearl River Estuary in summer by analyzing the TEP concentration and size-fractions of Chl a. TEP concentration (calculated by the amount of xan-than; the same below) ranged from 85.0μg•L?1 to 1234.9μg•L?1, with an average of 690.9μg•L?1. The averaged TEP concentra-tions in the surface layer and bottom layer were 562.3μg•L?1 and 778.2μg•L?1, respectively, and for most stations lower con-centration of TEP was found in the surface layer as compared to the bottom layer. In the surface layer, TEP increased from the up stream to down stream, and decreased gradually towards the open sea and towards the east and west in the estuary. In the bottom layer, the maximum TEP was observed in the S3 near Humen. The correlation between TEP and Chl a suggests that the excretion of naon-phytoplankton (3-20µm) may contribute more to TEP than other size phytoplankton. The ratio of TEP/(Chl a) shows positive correlation with salinity but negative correlation with nutrition (NO3—N, NH4—N, SiO3—Si and total phos-phorus).

Key words: the Pearl River Estuary, transparent exopolymer particles (TEP), chlorophyll
