Detection coastal thermal fronts in the Persian Gulf and the Oman Sea using MODIS images
MetadataShow full item record
Temperature fronts are important in marine studies. Sea fronts are sharp boundaries between different water masses. For this study different time series of MODIS level-3 thermal IR SST data from 2013-2014 has been processed and thermal fronts the of Persian Gulf and the Oman Sea (47.6°E to 67.7°E and 18°N to 31°N) region mapped using the method, the Canny algorithm and Gaussian filter. Monthly thermal front images of this region are mapped during the period of January 2013 to June 2014 are classified into Summer Monsoon (June, July, August, September), Winter Monsoon (October, November, December, January) and Pre Monsoon (February, March, April, May) periods and their characteristics are discussed here. The results show that high frequency of SST fronts was observed in the Oman Sea and Persian Gulf in October, November, December, January and May in 2013 year and January, November and December in 2014 year. The number of fronts increases since the beginning of winter to early.....
