Abstract: (17 Views)
Antarctica has become the focus of the world's attention in recent decades due to its importance in influencing the Earth's climate, huge potential resources, and its unique location and pristine environment. In the last decade, this issue has been given attention in our country, and even the region between 59.5 and 63.14 degrees east longitude has been declared as the target region of Iran, considering that one of the most basic conditions and stages of membership in Antarctica is the beginning of research activities in this region, especially the ecology of the region. In this research, the environmental characteristics of seawater in the targeted geographical area of Iran have been studied. Temperature and salinity profiles have been extracted for different seasons of the year. Because the main basis of the subsurface exploration is acoustic methods, in this research, the layering of the water column and the sound speed profile have also been calculated and analyzed. The analysis of the sound speed profile showed that in all seasons of the year, the trend of sound speed changes depends on the temperature, so it is possible to predict the way of sound speed changes with the help of temperature changes. Also, in the winter season, the signs of changes due to the different layers of the thermocline are clearly visible. Despite these changes, no audio channel is visible in the desired station in Antarctica.
