3.1. Spatial distribution of salinity, temperature, and CDOM absorption coefficient Spatial distribution of mean salinity, temperature, and CDOM absorption coefficient along transect with station 1 being a marine water end member while station 15 being a freshwater end member is illustrated in Figure 3. It is characterized by surface mean salinity gradient, ranging from (12.04±4.23) psu to (7.18±5.73) psu in spring, (24.26±0.91) psu to (0.31±0.30) psu in summer, (23.81±2.47) psu to (5.35±0.92) psu in fall, and (23.75±5.86) psu to (6.87±5.09) psu in winter from station 1 to station 15, respectively (Table 1). Weak salinity gradient in spring indicated influence of fresh water from the north to the south while strong gradients showed control of different factors on salinity in the north and south regions of the bay. Mean surface water temperature remained stable at all the stations with warmest temperatures of (30.05±0.75) °C to (29.8) °C in summer and coldest temperatures of (16.6±3.69) °C to (15.31±3.21) °C in winter from marine to freshwater end members. Mean CDOM absorption coefficient showed a sharp gradient, ranging from (3.42±0.35) °C to (7.41±0.63) °C in spring, (1.84±0.30) °C to (6.87±0.85) °C in summer, (1.65±0.36) °C to (6.41±0.98) °C in fall, and (2.11±0.77) °C to (7.68±1.8) °C in winter from station 1 and station 15, respectively (Table 2). Station 1 was characterized by approximately 46%, 52% and 38% higher CDOM absorption in…
