How is ocean mean temperature measured?

Ocean Mean Temperature(OMT) is measured up to a depth of 26 degrees isotherm. It is measured with the help of satellites that orbit the earth. In the Indian ocean, OMT is analysed by measuring the ocean thermal energy during the period from January to March. Scientists from Pune’s Indian Institute of Tropical Meteorology (IITM) find that ocean mean temperature (OMT) has a better ability to predict Indian summer monsoon than the sea surface temperature(SST).
