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.
通过毛细管显微镜测定了取自太平洋中部亚热带和赤道热带地区（西经135度和150度）以及印度洋西半部（东经65度）不同深度（0 - 5000米）的168份水样中的细菌总数和生物量。在大多数情况下，每1毫升水中含有数十万甚至数百万个细胞，其生物量为每立方米几毫克或几十毫克。不仅在表层，而且在较深的水层都发现了细菌含量高的水层。在真光层（0 - 200米），细菌生物量的平均值与热带辐散区和亚极地中营养水域浮游植物的生物量平均值相似。发现微生物总数的垂直分布与先前研究的腐生细菌分布相似。
