Abstract
The marine viral density in the Gwangyang Bay was abundant about 2.0 ×108 particles ml-1. For each season, viral abundances were recorded from 9.0 × 108particles ml-1 in summer to 0.7 × 106 particles ml-1 in winter. The spatial distributions ofthe viral, bacterial and phytoplankton biomass in the Gwangyang Bay were mostlyhigher in closed estuarine system (Station 2, 5, 10, 12, 16, 20) than open ocean systemindicated higher viral abundances, lower bacterial and plankton biomass than openoceanic system. In depths of some stations, the bacterial abundances exceeded ahundred fold than viral abundances. Seasonal abundances of marine viruses and theirhost systems were dynamically changed, and their seasonal variations were closelycorrelated. In summer, viral and bacterial abundances were increased, and phytoplank-ton chlorophyll a concentrations were maintained in average values. In winter, viraland bacterial abundances were dramatically decreased, and chlorophyll a con-centrations were decreased, but, immediately increased. The viral abundances werepeaked in August 2001, and bacterial abundance, in August 2001 and June 2002, whilechlorophyll a concentrations were peaked in April. 2002. In total host and viral abun-dances, it was seemed that their pools were maintained to steady-states by viral mor-tality, and viral abundance maintained steady -states. In our assessments, this report isa unique research about marine viral ecology of the Gwangyang Bay in Korea.
