A survey of literature and historical data was used to investigate the seasonal variations in the hydrographic and acoustic properties of the Persian Gulf. The Gulf has a year round salinity of about 40 parts per thousand by weight. The surface temperature varies from 30C in summer to 20C in winter. An area of significant importance in the Gulf is near the Strait of Hormuz where the Persian Gulf water encounters the warmer less saline water of the Arabian Sea. Detection ranges for diesel and nuclear submarines were investigated using the FACT acoustic transmission loss model. Generally, ranges appear to be greater in winter due to increased vertical mixing, creating strong positive sound speed gradients.
