Abstract

Oceans/Seas are important components of Earth that are affected by global warming and climate change; therefore, assessing them has become more important.  In the present study, changes in physicochemical parameters of water in the coral area of Chabahar Golf from April 2018 to March 2020 were investigated by C.T.D set. The results indicated that the temperature, salinity, dissolved oxygen, pH, turbidity, nitrite, phosphate and silicate did not differ significantly during the sampling period (p>0.05). However, nitrate and chlorophyll-a (Chl-a) showed a significant difference (p<0.05). Based on the results, the amount of nitrate in 2020 (2.89±1.05 mg/l) was significantly higher than in 2018 and 2019 (p<0.05). Nitrate content was measured 1.80±0.83 mg/l in 2018 and 1.05±0.49 mg/l in 2019. Nitrate content were not significantly different between 2018 and 2019 (p>0.05). The amount of Chl-a in 2019 (16.25±7.96 mg/m3) was significantly higher than in 2018 and 2020 (p<0.05). The amount of this parameter in 2017 was 3.11±0.92 mg/m3 and in 2020, it was 7.49±1.72 mg/m3. Chl-a content did not show a statistically significant difference between 2018 and 2020 (p<0.05). In conslusion, the results of this study indicated that the condition of physicochemical parameters of water of investigated region were relatively stable during the sampling period.
