Advances in Glacier Hydrology

Session ID#: 83343

Session Description:
This session explores the role of water on, in, and under glaciers and ice sheets, as well as its impact 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 glacier hydrology, including the variability of these connections in space and time, strengthens our ability to predict how glacial systems will respond under 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.
