In this study, we investigated the relationship between environmental parameters (water and sediment) benthic foraminiferal assemblages found in nearshore siliciclastic sediment Arabian Gulf. Nearshore marine water samples were collected from a beach on Gulf of Bahrain located south Al Khobar, Saudi Arabia. The analyzed for biochemical oxygen demand (BOD5) other chemical analyses. tested (SOD) heavy metal analysis. Results showed BOD5 levels below detection limit (<1 ppm), while mean SOD value was 0.97 ± 0.08 g/m2·day. sediments unpolluted free eutrophic enrichment, anoxic. two most common genera assemblage, Ammonia Elphidium, are typical shallow sandy substrates. This is first reported comparison assemblages.
