[1] Distribution of Transparent Exopolymer Particles (TEP) in the Pearl River estuary, China, was investigated during two cruises in August 2009 and January 2010. TEPcolor concentrations were 521.5–1727.4 mg Xeq.L1 (mg Gum Xanthan equivalent liter1) in August 2009 and 88.7–1586.9 mg Xeq.L1 in January 2010, respectively. The size of TEP generally increased in the seaward along the longitudinal section with the dominant size of 2–40 mm during the cruises. Experimental work suggested that both concentration and size of TEP increased with Ca2+ concentration (from 0.8 mmol L1 to 10 mmol L1). In the field study, Ca2+ concentration had a positive correlation with TEPcolor concentration in the surface layer with salinity
