Description Surface seawater samples were collected over a period 33 of 27 months at a shallow water station in Dona Paula bay from 1998-2000. The samples were analyzed to assess the seasonal variations, inter-annual variability and the contributions of i) transparent exopolymeric particles
(TEP) concentration, ii) two forms of particle-associated carbohydrates- 1.5M NaCl/saline extracted (Sal-PCHO) and 10mM EDTA-extracted (CPCHO) and iii) total bacterial abundance (TBA) to particulate organic carbon pool. A distinct inter-annual variability was observed with an increase in the bacterial abundance, chlorophyll a (chl a), TEP and Sal-PCHO and their greater contribution to particulate organic carbon during May 1998-1999 than in June 1999- July 2000. Overall, there was no statistically significant correlation of TEP with phytoplankton biomass (Chl a), Sal-PCHO, CPCHO and hydrodynamic conditions. A weak inverse correlation was observed between TEP and TBA (r= -0.397; p
