Scientists have created a new geological map of Greenland revealing its varied landscape beneath the ice, which can improve understanding of GPS accuracy and predict ice-sheet stability.
According to William Colgan, the study co-author, most people perceive Greenland as a uniform landmass. However, individual geological features might shift and twist beneath the ice.
Sridhar Anandakrishnan notes that mapping the geology of Greenland based solely on coastal rocks is inadequate, like trying to determine Nebraska's geology from regions like California or New York.
The study reflects the progress since 2009 due to advancements in technology, including satellites and seismic stations, that provide more comprehensive datasets for accurate geological mapping.
