Abstract

Surface currents have great importance in marine studies. These currents can be an important factor in the transfer of density, nutrients or pollutants into the ocean environment. The water area of the Persian Gulf and the Sea of Oman is one of the most important waterways in the world. In this study, HYCOM current data in 2019 are used and the currents of the Oman Sea are surveyed month by month in same year, in GIS software. The strongest currents of the Oman Sea are forming in autumn and winter (in January and March). The shape of the currents is cyclic in winter and marginal and strong in autumn. The diameter of the January cycle is about 235km. The southern border current in October is about 390km and it is leaving the Oman Sea.  The highest value of velocity in the Oman Sea is 1.1m/s and the lowest value is 0.001m/s. The inflow to the Persian Gulf has less salinity and more velocity than the outflow.
