With reference to Ocean Mean Temperature (OMT), which of the following statements is/are correct? 1. OMT is measured up to a depth of 26 degree C isotherm which is 129 meters in the south-western Indian Ocean during January-March. 2. OMT collected during January-March can be used in assessing whether the amount of rainfall in monsoon will be less or more than a certain long-term mean. Select the correct answer using the code given below:

1. Incorrect. OMT is linked to the heat content of the upper ocean above the 26°C isotherm, but the statement gives a very specific value: 129 m in the south-western Indian Ocean during January–March. This is not the standard defining feature of OMT and, as framed, is not accepted as a universally correct statement in UPSC.

2. Correct. OMT data for January–March has been used to assess whether the summer monsoon rainfall is likely to be above or below the long-term mean, since it reflects upper-ocean heat content better than SST alone.

Therefore, only statement 2 is correct.
