Africa-Press – Mauritius. <\/strong><\/span>Scientists might be getting closer to an understanding of how the Antarctica and its underground waters are responding \u2013 or even contributing \u2013 to climate change.<\/p>\n

Over the course of recent years, scientists have discovered a network of rivers and lakes that exist within the Antarctic ice, while also imaging thick basins of sediments under the ice that could potentially contain the biggest water reservoir on the planet, according to a new study.<\/p>\n

The findings resulted in scientists piecing together a huge map of the groundwater system in deep sediments in West Antarctica. Such systems may indicate the continent\u2019s response to climate change, or even how it might contribute to it.<\/p>\n

Before the study, evidence pointing to the fact that there is a massive groundwater reservoir below the Antarctic ice had been quite elusive. But the new findings seem to have changed the picture.<\/p>\n

In order to map the groundwater systems in Antarctica, the researchers behind the study used magnetotelluric and passive seismic data from the Whillans Ice Stream of West Antarctica.<\/p>\n

The technique of magnetotelluric imaging measures the penetration into the earth of natural electromagnetic energy generated high in the planet\u2019s atmosphere.<\/p>\n

Ice, sediments, salty water and other things emanate different types of such energy, so, having measured the differences, one could create MRI-like maps of various elements.<\/p>\n

\u201cThis groundwater, extending downward for more than a kilometre, contains more than 10 times as much fluid volume as the shallow hydrologic system above and actively exchanges with it. Therefore, it has the potential to modulate ice streaming and subglacial biogeochemical reactions,\u201d the study\u2019s abstract notes.<\/p>\n
