Short summary
Supraglacial drainage systems mediate meltwater transport over ice shelves and may influence their stability. Our mapping of Nivlisen Ice Shelf from satellite imagery shows significant variation in interannual and seasonal drainage extent. During warm summers, channels become increasingly connected, redistributing meltwater from high to low elevations across the ice shelf. Channel location is controlled by ice shelf structure, and annual extent is correlated with regional air temperature.
