Scientists have since established the existence of about 280 "subglacial" lakes, most located below the East Antarctic ice sheet.
According to TIME and the paper's abstract, the team created models based on the formation of similar terrain on Earth -- subglacial volcanos and ice shelves -- to determine how the chaos terrain on Europa could have formed.
Russian and American researchers, including Christner, have identified signs of life almost three miles below the surface in ice that originates from liquid Lake Vostok, the largest of the recently discovered subglacial lakes on the continent.
“A contemporary microbially maintained subglacial ferrous ‘ocean.’”
While Vostok is the largest subglacial lake in Antarctica, there are hundreds of others.
The AGAP (Antarctica's Gamburtsev Province) project will establish two camps from where the team will map the subglacial range using surface and airborne instruments.
Using radar and gravity sensors, the experts made the first detailed maps of the Gamburtsev subglacial mountains, originally detected by Russian scientists 50 years ago at the heart of the East Antarctic ice sheet.
At this point, computer models do not show how the subglacial water is moving around.
There are three subzones: subglacial, from 2,000 m to 3,000 m which is unglaciated; a glaciated subzone between 3,000 m and 5,300 m, with arêtes, cirques, and U-shaped valleys with meandering rivers, and a volcanic subzone dominated by lava and volcanic ash deposited during more recent times on the cones and flanks of the three volcanoes.
By determining the date of an ancient subglacial flood, scientists have linked it to a global warming trend.
