Subglacial hydrology can exert an important control on ice flow by affecting friction at the ice-bedrock interface. Here, we report on a series of subglacial drainage events along the Northeast Greenland Ice Stream (NEGIS), initiating as far inland as 500 km from the margin of Zachariae Isstrøm. The...
