Spatio-temporal variability of SST and Chlorophyll-a from MODIS data in the Persian Gulf.

Spatio-temporal variability of SST and Chl-a evaluated using MODIS products from 2002 to 2013 in the Persian Gulf. Wavelet Transform was utilized to analyze the spatio-temporal stability and abnormality of MODIS SST and Chl-a. The stationary level of SST decreases from west to the east during summer to early autumn, and increases from late autumn to spring. The stationary level of Chl-a is higher in the coastal areas, while its average ranged from 0.1 to 0.5mgm(-3). No meaningful major oscillating period observed in the abnormal variability of SST and Chl-a. The winter and summer peaks of SST and Chl-a were observed in the central parts and north-west regions. The timing of maximum SST was observed in August, which is not correlated with Chl-a maxima. The variability of SST and Chl-a in the whole Persian Gulf is seasonal, and related to river outflows, water circulation and climate regimes.
