Advances in Glacier and Ice Sheet Hydrology
Session ID#: 157464
Session Description:
This session explores the role of water throughout glaciers and ice sheets and the impact of water on ice dynamics, mass balance, and geomorphology. Water is stored and transported through glaciers by 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 the bed, modulates glacier velocities, redistributes glacier mass, and facilitates glacial erosion. Advances in glacier hydrology, including the variability of these connections in space and time, strengthen our ability to predict how glacial systems respond to a changing climate. We invite contributions from all aspects of supraglacial, englacial, and subglacial hydrology and particularly welcome studies focusing on interactions between multiple components of the glacier hydrologic system.
