Scientists have found that the sea-level around the coast of Antarctica is rising at a faster pace than expected.
According to the scientists, they have concluded the findings following a thorough analysis of 19-year data collected by the satellites.
The data revealed that the fresh water from melting glaciers has lifted the sea-level by two centimeter more than the global average of six centimeter.
Briefing about the findings in a press release, lead author Craig Rye said, “Freshwater is less dense than salt water and so in regions where an excess of freshwater has accumulated we expect a localized rise in sea level.”
The researchers examined the scans captured from the satellites of a region which is over a million square kilometers long in order to measure the exact extent up to which the sea levels have risen over the years.
Computer simulations were also conducted to find out the impact of melting glaciers on the Antarctic Ocean.
Talking about the findings of simulations, the lead researcher said, “The computer model supports our theory that the sea-level rise we see in our satellite data is almost entirely caused by freshening, i.e. a reduction in the water salinity, from the glacier melting and its fringing ice shelves.”
Rye further said, “The interaction between air, sea and ice in these seas is central to the stability of the Antarctic Ice Sheet and global sea levels, as well as other environmental processes, like the generation of Antarctic bottom water, which cools and ventilates much of the global ocean abyss.”
Following a deep analysis of all the available data, the scientists discovered that the melting of glaciers along with the thinning of the floating ice shelves have led to the release of about 350 gigatons of freshwater into the Atlantic ocean.
Scientists say this process has led to the lowering of salinity.
Environmental scientists say the findings reveal that if the sea levels continue to rise with the similar pace then some big changes in the region is tend to happen. The gradual reduction in the salinity levels could pose major threat to the marine life and ecosystems in the region.
The findings of the study were published in the journal Nature Geoscience.
