 Context:  A recent study by the Indian Institute of Tropical Meteorology (IITM) predicts a significant warming of the Indian Ocean, leading to a tenfold increase in marine heatwaves, from an average of 20 days per year to 220–250 days per year. The Arabian Sea experiences maximum warming.

 

Consequences:

This warming trend, largely attributed to global warming, is expected to have severe consequences, including coral bleaching, seagrass destruction, and loss of kelp forests, adversely impacting the fisheries sector. The study also highlights a substantial increase in the ocean’s heat content, which contributes to sea-level rise and affects the Indian Ocean Dipole (IOD), potentially altering monsoon patterns.

 

About the Indian Ocean: 

The Indian Ocean is the third-largest ocean in the world, covering an area of over 70 million square kilometers. It is bounded by Africa to the west, Asia to the north, Australia to the east, and the Southern Ocean to the south. The ocean is known for its warm waters and diverse marine life, including coral reefs, whales, dolphins, and various species of fish.

 

Oceans on Earth are (larger to smaller): the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern Ocean, Arctic Ocean
