[Total number, biomass and production of bacteria in the water of the subtropical and equatorial-tropical regions of the Pacific Ocean].
The total number and biomass of bacteria were determined by capillary microscopy in 168 samples of water taken from different horizons (0-5,000 m) in the subtropic and equatorial-tropic regions of the central part of the Pacific Ocean (135 degrees and 150 degrees w. long) and the western half of the Indian Ocean (65 degrees e. long). In most cases, 1 ml of water contained dozens and hundreds of thousands of the cells whose biomass was several or dozens milligrams per 1 m3. Layers with a high content of bacteria were encountered not only in the surface zone but also at large depths. In the euphotic layer (0-200 m), the mean value of the bacterial biomass was similar to that of phytoplankton in mesotrophic waters of tropic divergences and subpolar zones. Vertical distribution of the total number of the microorganisms was found to be similar to distribution of saprophytic bacteria studied earlier.
