Comments Off on West Antarctica’s bedrock is rising, providing some protection to melting ice

It seems that most news concerning Antarctica’s ice sheets is bad news, with two of the world’s fastest melting glaciers shrinking away in the continent’s western region. Fortunately, this same region is also home to an unusual geological feature that may provide some relief to the effects of climate change. In a new study published in the journal Science , researchers examined how the Earth’s surface seems to expand when heavy objects, such as glaciers , are no longer present and pushing down on the ground. According to data gathered from GPS sensors, the land beneath the Amundsen Sea Embayment in western Antarctica is rising at a rate of about two inches per year, one of the fastest rising rates ever recorded. As is often the case, the discovery of western Antarctica’s rising bedrock was made somewhat by chance. “[Study co-author] Terry Wilson and colleagues were extremely wise and lucky,” study co-author Valentina Barletta told Earther . “They had the really, really good idea [to place those sensors] with very few indication[s] that there might have been something special.” The researchers concluded that the land beneath the Amundsen Sea Embayment springs back because of a relatively fluid mantle beneath the surface, which is more capable of responding to changes above.

Understanding the impact that rebounding land can have enables researchers to more accurately assess ice loss, the measurement of which has been incomplete due to a lack of knowledge about rising rock. The study also provides some hope to those who live in coastal areas, which may benefit from the potential slowing of melting ice by its rising higher than the warmer water .
