Title: The glacier bed - does it know it's raining.
A statistical study of two decades of subglacial and hydro-meteorological data.
Speaker: Pierre-Marie Lefeuvre (UiO/NVE)
Abstract:
At the Svartisen Subglacial Laboratory, pressure cells installed at the ice rock interface under ~200 m of glacier ice have been recording basal pressure for 20 years. Five sensors in particular are studied, covering a 22m zone, that generally show correlation in the sensor response to changes in the subglacial hydrology. By studying the nature of this correlation as well as the correlation (or anti correlation) between sensors, it is possible to investigate the evolution of the degree of connectivity at the glacier bed. Significant changes in connectivity on an annual basis are reported and its potential impact on glacier flow is discussed.
