| Abstract | ||
| Compared to many world seas, the Red Sea is the warmest and the saltiest; it is characterized by low rainfall, no river flow and high evaporation rates. The optical characteristics of the seas and oceans are influenced by hydrological, biological and environmental conditions. Optical characteristics vary in the North of Safaga Bay due to the different hydrological conditions affecting the area. Temporal and spatial variations were detected in the incident solar radiation at the study site since each station is affected by different conditions. The impact of temperature and salinity on optical properties becomes clear upon applying the correlation between them. The average water temperature, water salinity, the intensity of the incident and irradiated flux intensity, transmittance, absorption and attenuation coefficient were 25.21oC, 42.10psu, 1420.26 w/m2, 74.84w/m2, 0.008, 0.92 and 0.85, respectively. Increased water temperature and low water salinity were associated with an increase in the intensity of radiation flow and frequent water transport. While an increase in the absorption and dispersion factors were aligned with lower water temperature and higher salinity. | ||
