The deepest water in the world disappears mysteriously

According to the US National Oceanic and Atmospheric Administration (NOAA) report, Antarctic bottom water (AABW) is disappearing with an average rate of about 8 million tons per second.

This is the result of the research data from 1980 - 2011 of oceanographers.

AABW is the deepest and coldest water in the world, formed in certain places around Antarctica. The water here is salty and denser than the water in the surrounding areas, so it sinks to the sea floor, flows northward, spreading to most oceans in the world.

The reason why this water gradually disappeared is still a mystery for scientists.

Oceanographer Gregory C. Johnson at NOAA's Pacific Marine Laboratory, said: 'We are not sure whether this declining rate is part of a long-term trend change or a cycle. '.

Previous studies have shown that ocean currents from this water are becoming warmer and fading.

These currents play an important role in transporting heat and carbon around the planet, regulating the Earth's climate.

Changes in temperature, salt content, dissolved oxygen and dissolved carbon in this water area affect the Earth's climate, including rising sea levels and warming climates.
