Gulf of Oman's 'dead zone' is expanding, Arabian Sea's 'dead zone' the largest

A huge ‘dead zone’ in the Gulf of Oman is growing in size, as suggested by researchers who have warned that the oxygen-rare territory is dangerous than earlier thought and represents a risk to the planet earth.

The ‘dead zone’ in the Arabian Sea is currently the world’s most Oxygen Minimum Zone (OMZ). About the size of Scotland, the ‘dead zone’ covers about the whole Gulf of Oman.

A dead zone is a region of the ocean that has no oxygen. The regions are called dead zones as they don’t and can’t support marine life.

Researchers started spotting growing regions of the dead zone in the 1970s.

The existence of the Gulf of Oman’s dead zone has been known for 50 years now, yet the degree of the zone has just been confirmed on the account of utilization of underwater robots, known as Seagliders.

The Arabian Sea is the biggest and thickest dead zone on Earth.
