Estimation of primary production in the Mahshahr creeks(Khozestan-Persian Gulf) using field and remote sensing data

Primary production is an important indicator of aquatic ecological systems. The spatial and temporal pattern of OPP is helpful for global climate change study. In this study the spatial and temporal variability of primary productivity in the 3 creeks of Northwest of Persian Gulf from Feb 2014 to Nov 2014 was estimated using a VGPM primary productivity model and insitu measurement. Single Peak of primary productivity appeared in April (0.356 gc/m2/d) and fall in July (0.217gc/m2/d). From the correlation analysis, we found that observed primary production has a good relationship with measured primary production (p<0.01,R2=0.60). A linear regression was then established to quantify the relationship between them. The RMSE of its function was good (0.3 mg/m3). In summary, the Landsat8 data are potentially capable of monitoring Case-II waters such as this creeks to some extent Published
