Scientists have pointed out that the Indian Ocean is losing its salt, and it is going to have a massive impact on the weather patterns across the country. According to experts, the Southern Indian Ocean has become noticeably "fresher" over the last 60 years.
The University of Colorado Boulder, in its latest report, 'One of the saltiest parts of the ocean is getting fresher' revealed that the South Indian Ocean off the west coast of Australia is becoming less salty at a surprising rate.
The report also suggested that salinity has reduced to around 30 per cent. Though it is not alarming, it is definitely concerning. Ocean salt is not just about taste; it affects currents, climate, rainfall, and marine life.
The waters south of Australia were one of the saltiest anywhere. Researchers are tracking the latest shift with buoys, satellites and sensors on ships.
How will it impact the Indian climate
As far as India is concerned, the dip in salinity could have a serious impact. The Indian Ocean is key to monsoons, and it drives the rainfall patterns.

Changing currents are pushing Indo-Pacific freshwater into the Southern Indian Ocean, reducing the water's density and preventing it from sinking. Saltier water normally sinks, while fresher water floats. This imbalance threatens to derail global ocean circulation, potentially destabilising climate systems far beyond the Indian Ocean basin.
If the currents change, rainfall patterns may shift. It may be heavier or lighter than usual. Marine ecosystem, plankton, and fish migration may be affected due to this change.
Not just India, the European and African climate could have a slight impact due to this shift, as oceans are interconnected.
