A new study conducted by the researchers over Antarctica found surprising results. The bedrock below the continent is notably rising very rapidly as compared to its previous rates. The present rate at which the west Antarctica bedrock is raising was reported to be around 41 millimeters (1.6 inches) per year.
The reason behind this unusual rate may be the fact that as the ice in that region is melting, its mass on the underlying bedrock is lightening. This being said, as a massive amount of ice has melted already, the land is getting pushed up due to the strong mantle flow occurring below the surface of the Earth.
The inferences of the study have taken the researchers by surprise who previously thought that the future of the ice sheet of West Antarctica would be bleak due to the effects of the climate change. This study has given the scientists some positive hopes regarding the future of the West Antarctic Ice Sheet (WAIS). This rapid rate at which the Earth is rising in West Antarctica could dynamically hike the survival rate of the West Antarctic Ice Sheet against the catastrophic collapse by making them more stable.
However, this land rising phenomenon could pose to be a bad picture too. As regarded by the scientists involved in this research, the rising of the Earth in West Antarctica tends to affect the gravity measurements in that region. This has led the scientists to underrate the rate at which the ice sheet is vanishing by near about ten percent.
As a part of the study, the researchers at the Ohio State University made use of a range of 6 GPS stations connected to the bedrock surrounding the Amundsen Sea Embayment for estimating its rise with respect to the thinning of the ice.
Prof. Terry Wilson, one among the study’s head at the Ohio State University, said in a statement, “The rate of uplift we found is unusual and very surprising. It’s a game changer.” As reported by the scientists, this rate would only increase further. The researchers predicted that within the next hundred years, the rate of the rising land in that region would increase by near about 2.5 to 3.5 inches in comparison to the current rate.
The observations of this new study were published in the Science journal.
