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°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. Statement 1 is incorrect. Ocean Mean Temperature (OMT) is generally calculated by averaging the temperature over a specific upper layer of the ocean, often defined by a fixed depth (e.g., top 50 or 100 meters). It is not typically defined by the depth of a specific isotherm like 26°C, as the depth of an isotherm varies significantly with location and time. The specific value of 129 meters for the 26°C isotherm in the south-western Indian Ocean during January - March might be an observation for a particular instance but doesn't represent the standard method for measuring OMT. 2. Statement 2 is correct. OMT represents the heat content of the upper ocean layers. Studies have shown that OMT, particularly in the tropical Indian Ocean, collected during the pre-monsoon months (January - March), is a crucial parameter influencing the development and intensity of the subsequent Indian summer monsoon. Higher OMT generally indicates more heat energy available, which can potentially lead to stronger monsoons. Thus, it can be used in assessing whether the amount of rainfall in monsoon will be less or more than a certain long-term mean.
