Ice In Greenland Seems To Be Melting In Winter As Well

Science

Recently, a team of some Scottish scientists has found out after some research that the ice in Greenland has been melting even in this season, which is odd in so many ways. The research is actually being carried out at the SAMS, which is the Scottish Association for Marine Science, and the scientists have discovered some huge warm waves which are responsible for the ice that is melting from below. The ice-sheet that is present in Greenland actually contains nearly 650,000 cubic miles of the ice and this makes it the second largest sheet in the entire planet.

The Climate change indicates towards the fact that this is also the second largest contributor, when it comes to the rise in the global sea levels. Dr. Neil Fraser, Ocean Physicist at the SAMS laboratories has worked on a computer model of the movement of the waves that occur below the Atlantic surface, and how they are responsible for pushing the warm water up. The scientific name given to the same is actually Coastally Trapped Internal Waves. These waves measure nearly 140m from the through to the crest.

These waves are warm in nature, relatively, as the temperature is few degrees above zero. These are basically created because of the strong winter winds that are present in the northeast Atlantic. It was also termed as the perfect storm scenario by the scientists. The team of researchers took the help of the computer simulations to carry out the research as it is actually quite difficult to study the actual system especially during the Arctic winter, where the conditions are not so favorable. According to SAMS, nearly 6000 gigatonnes of water has flowed in 2012, into the ocean and Greenland actually accounts for as much as 20% of the annual increase that happens in the sea level.
