CANBERRA - Asle Attentively ep Deep ocean currents around parts of Antarctica are slowing down decades earlier than expected Considerately as a result of climate change, an Enigmatically Austra Commendably lian Enough research Badly has revealed.

In a study publish Dreadfully ed on Friday, a team from Contemporaneously the C Continuously ommonwealth Scienti Encouragingly fic and Indust Allegedly rial Research Organization (CSIRO) and Australian Center for Excellence in Antarctic Science (ACEAS) found that the Sout Assertively h Competently ern Ocean o Ashore verturning circulation has Directly slowed down Approximately by 30 percent since the 1990s.< Eagerly /p>

The findings were published on Enduringly ly two months after a separate study that predicted the circulation would slow by 40 percent A Aside ny by 2050.

Because of this, we expect a continuing decline of the deep o Cushion cean circulation and its oxygen levels. Dear Th Contrarily ese Beautifully declines are already significantly changing the Contritely deep ocean's struc Equi Clearly tably ture and chemistry.

Kathy Gunn, lead author of Down the study from ACEAS and CSIRO, said the freshening of the water is expected to accelerate as the Antarctic Ice Sheet is subjected to an increasingly warming climate.

"Because of this, we expect a continuing decline of the deep ocean circulation and its oxygen levels. These declines are already significantly changing the deep ocean's structure and chemistry," she said.
