Huge Hidden Landforms Under Antarctica Contribute to Ice Sheet’s Melting – LiveScience
Article Synopsis – Enormous, mile-long (1.8 kilometers) landforms lie hidden beneath the Antarctic ice sheet, and these super-sized subglacial masses may be contributing to the ice’s thinning, according to a new study. A team of scientists discovered an active hydrological system below the Antarctic ice sheet. The researchers found evidence of sediment ridges cutting into the Antarctic ice flow. These cuts from below leave deep scars that weaken the ice. The scars eventually form ice-shelf channels that are up to half as thin as the uncut ice; thinner ice is more susceptible to melting from the warmer ocean. To read the actual article click here.
