Interrelations of phytoplankton, chlorophyll and physic-chemical factors in Arabian Gulf and Gulf of Oman during summer

257-261Samples for phytoplankton counts and chlorophyll data were collected from two areas, east of the strait of Hormuz (in Gulf of Oman) and west of this strait (in Arabian Gulf), during September 1986. Phytoplankton counts were higher in the west of Hormuz strait than in the Gulf of Oman. Horizontal distributions of some biological and hydro-chemical factors reflected the influence of known current system near southern side of Arabian Gulf. Generally, the most important nutrient salts affecting the phytoplankton growth, deduced from stepwise regression analysis, were nitrogen and silicon compounds
