The rise in the sea level around the Antarctica coast would be faster than the global rate that is projected, say the experts from University of Southampton report in a Southampton report in research appearing Sunday in the advanced online edition of the journal Nature Geoscience.
In this paper, lead author Craig Rye as well as his colleagues from National Oceanography Center, Scottish Association for Marine Science as well as the British Antarctic Survey explain that due to the Satellite data from last 19 years, it has been revealed that there is a rise in the sea level by 2mm owing to melting glaciers.
Researchers said that this rapid increase in sea level was detected after satellite scans were studied of area spanning more than 1 million sq.kms. They also stated that an estimated 350 gigatons of additional freshwater is added due to thinning of floating ice shelves and melting of Antarctic ice sheet.
As a result, there has been a reduction in the salinity of ocean water. Rye explained that since the density of freshwater is less than the salt water, localized increase in sea level will be experienced by regions that accumulated excess of fresh water.
The authors said that most of this increase in freshwater in found in Antarctic Peninsuala as well as Amundsen Sea and with the help of satellite measurements combined with computer simulations of ocean circulation, it was found that sea level increase was greater than regional mean.
Based on the model simulations, it can be concluded that this rise in the sea level has a relation to steric adjustment rather than changes in Local Ocean mass.
