The Gulf of Gorgan

The Gulf of Gorgan is the largest gulf located on the Iranian shores of the Caspian Sea. The Gulf of Gorgan was formed with the advancement and expansion of the coastal peninsula of Miyankale in the southeast of the Caspian Sea. The Gulf of Gorgan is shallow, in fact, its maximum depth reaches 4 meters. From east to west, near the southern side of the Ashurade peninsula, the depth of the gulf increases due to the presence of fresh-water river mouths, such as the Qara Su River and the Gohar Baran River, thereby decreasing the degree of salinity and that of the turbidity of the waters of the Gulf of Gorgan.
