Man-Made Impact on Climate Changing Antarctic Waters

The densest waters of Antarctica have reduced dramatically over the recent decades. A study on this phenomenon comes about as shocking, and discloses the intensity of environmental degradation. Australian scientists who conducted the study say that the change in the waters is part due to the man-made impacts on climate.

Up to 60 percent of the dense water formed around the edges of Antarctica called Antarctic Bottom Water, which seeps into the deep sea and spreads out through the world’s oceans, has disappeared since 1970.

Steve Rintoul, from the Australian government’s Commonwealth Scientific and Industrial Research Organisation, states that this happened because of the climatic changes in the polar regions, due to both natural and human causes. The phenomenon is not leading to any further changes in the climate, however. But the issue itself is a response to the changes in the climate.

Well, the study does not made any statement regarding the actual cause of the problem. The leading hypothesis of the research is that as more of the ice on Antarctica melts around the edges of that continent, it adds fresh water to the ocean, thereby reducing the density of the water.

The research  was done by Australian and US scientists onboard the Australian Antarctic Division’s vessel Aurora Australis. The team sailed to Commonwealth Bay, west along the Antarctic coast, and the journey ended at Fremantle in Australia.
