The PolarGAP project was therefore designed to fill in the gap in the satellite data coverage of the South Pole and in particular acquire the missing gravity data. Airborne radar data were also collected to enable mapping of the bedrock topography hidden beneath the ice sheet. The data reveals the topography which controls how quickly ice flows between the East and West Antarctic ice sheets.<\/p>\n<p>The team, led by Northumbria University, has mapped for the first time three vast, subglacial valleys in West Antarctica. These valleys could be important in future as they help to channel the flow of ice from the centre of the continent towards the coast. <a href=\"https:\/\/www.northumbria.ac.uk\/about-us\/news-events\/news\/2018\/05\/polargap\/\" target=\"_blank\" rel=\"noopener\">Read more.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The findings are the first to emerge from extensive ice penetrating radar data collected in Antarctica as part of the European Space Agency PolarGAP project and have been published in the journal, Geophysical Research Letters.
