The Ocean Mean Temperature (OMT) is measured by satellites orbiting the Earth in order to calculate sea surface temperature (SST) and forecast monsoons. The ocean limits temperature calculation to a depth of 26 degrees isotherm. Scientists use a variety of equipment to measure OMT.

Measurement of Ocean Mean Temperature

The ocean temperature in the Indian Ocean is calculated not only to determine the sea temperature but also to predict the onset of the monsoon. From January to March, the OMT is calculated by measuring the ocean’s thermal energy. The satellites measure the amount of energy produced in the ocean at various wavelengths.

Many students may wonder why OMT is so important to measure. Scientists use OMT to check the communication between the earth’s atmosphere and the ocean’s water. Because water covers more than 71% of the Earth’s surface.

Facts about Ocean Mean Temperature

Some quick facts about OMT are given below:

  • The Persian Gulf is the hottest area of the ocean.
  • In the summer, water temperatures in the Persian Gulf can reach 90 degrees Fahrenheit.
  • The temperature of ocean water varies according to location and longitudes/latitudes.
  • Antarctic sea ice is the coldest, with an Ocean Mean Temperature of -1.8 degrees Celsius.
