Small DAPI-positive, virus-like particles (VLP) were found to be distributed throughout the water column down to 5000 m at both of the stations. The abundance of VLP ranged from 38 x 105 ml-1 at 50 m depth to 0.6 x 105 ml-1 at 5000 m depth at Stn A. The ratio of VLP to bacteria-like particle (BLP) ranged from 1.1 to 7.4 at Stn A and 1.0 to 8.7 at Stn B in the entire water column. The maximum ratio was recorded at Stn B from the deepest sample, collected at a depth of 5000 m. The electron microscopic investigation indicated that the major proportion of VLP were probably viruses.
