The objective of this research was to develop a model for estimating chlorophyll-a concentration, SST and kd(490) on the Northwest Persian gulf by means of a high resolution landsat8 image. Field studies were conducted monthly (two months of every season of year including Feb, March, April, May, July, Agust, Oct and Nov) from water concurrent with the passage of satellite in Mousa estuaies on 14th Feb 2014 to 13th Nov 2014 from 3 station located in the northwest Persian gulf. Temperature, Secchi disk depth, chl-a, kd and zeu was measured in this study. The Chl-a concentrations ranged from 0.1 to 1.6 mg m−3, with an average of 0.6 ± 0.42 mg m<sup>−3</sup>. Only two algorithms OC-2 and Morel-3 could meet the requirements of the evaluation criteria. The values for Kd(490) were highest(0.86) in July and lowest (0.59m) in February. The optimal SST model was found in this zone. The retrieval accuracy (R2) was 0.63, while the root mean square (RMSE) was 0.81. The highest (31c°) temperature was found in July and lowest temperature(15.1c°) was found in Feb. There was a significant positive correlation between Kd(490) and chl-a. There was a significant positive correlation between SST and chl-a. |
