Research: Glaciers in Southern Antarctic Peninsula region are receding

The reportedly disquieting melting of ice in the Antarctic Peninsula region has seemingly triggered a series of alarming news. A few days back, researchers had revealed that Larsen C is melting, and the residual portion of the Larsen B ice shelf will probably disintegrate completely by 2020.

Now, researchers from the University of Bristol in Britain, along with researchers from Germany, France and the Netherlands have unveiled that glaciers in a region known as the Southern Antarctic Peninsula are retreating.

Things were perfectly fine till 2009 and soon after that a major portion of the region became destabilized. The researchers have based their findings using satellite based and gravity measurements.

One of the reasons considered behind the ice melt is warmer waters, which is reaching at the base of the submerged ice shelves holding larger glaciers. The event has not happened for the first time as similar phenomenon was held accountable for melting of ice shelves in nearby West Antarctica.

Study’s co-author Jonathan Bomber of the University of Bristol said, “This is one of now three really quite substantial signals that we’ve seen from different parts of West Antarctica and the Antarctic Peninsula that is all going in the same way”.

The researchers said that the main thing to notice is the all of sudden change. As per the researchers, the region is losing ice at the rate of 56 gig tons of ice per year. The glaciers now seem to be unstable, as some of the ice shelves standing on bedrock are below sea level.

The research paper unveiled that this region of Antarctica is adding around .16 millimetres to sea level rise each year. Researchers said that the total sea level rise is not only due to contributions made from Antarctica, but from other places as well including Greenland, polar ice across the world and thermal expansion of sea water.
