1993年8月至9月期间，通过测定二乙烯基叶绿素a（divinyl Chl a）来测量中太平洋沿56°长的经向（175°E）横断面原绿球藻的丰度。本研究的目的是调查原绿球藻的大尺度空间分布模式，评估其对浮游植物总生物量的贡献，并确定其在中太平洋分布的环境边界海洋。原绿球藻在透光带以下的深度（总叶绿素的 50%（二乙烯基叶绿素 + 叶绿素）高于 1% 等量）被检测到，通常发生在 15-30°C 和 0-10 μM 硝酸盐加亚硝酸盐之间。
The abundance of the prochlorophyte Prochlorococcus along a 56°-long meridional (175°E) transect in the central Pacific was measured by determining divinyl chlorophyll a (divinyl Chl a) during August and September 1993. The aims ofthis study were to investigate the large-scale spatial distribution patterns of Prochlorococcus, to evaluate its contribution to total phytoplankton biomass, and to identify the environmental boundaries of its distribution in the central Pacific Ocean. Prochlorococcus was detected at depths below the euphotic zone ( 50% of the total Chl a (divinyl Chl a + Chl a) above the 1% isolume and generally occurred between 15-30°C and 0-10 μM nitrate plus nitrite.
