The study of changing in water physicochemical parameters of coral area in Chabahar Golfs

Abstract

Introduction: Oceans/Seas are important components of Earth that are affected by global
warming and climate change; therefore, assessing them has become more important.
Materials & Methods: 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.
Results: 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±7.96mg/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).
Conclusion: In conclusion, the results of this study indicated that the condition of
physicochemical parameters of water of investigated region were relatively stable during the
sampling period.
