This session explores the role of liquid water throughout glaciers and ice sheets as well as the impact of water on ice dynamics, mass balance, and geomorphology. Water is both stored and transported through glaciers by a series of connected supraglacial, englacial, and subglacial features including supraglacial lakes, streams, and saturated snow; englacial crevasses, moulins, and incised channels; and subglacial drainage channels, cavities, saturated till, and frozen sediments. Connections between these components shape the glacial hydrologic system, which transports water from the surface to bed, modulates glacier velocities, redistributes glacier mass, and facilitates glacial erosion. Advances in observing, inferring, and modeling glacier hydrology, including variations in space and time, strengthen our ability to predict how glacial systems will respond under a changing climate. We invite contributions considering any aspects of glacial hydrology, and particularly welcome studies focusing on interactions between multiple components of the glacier hydrologic system.
