Modeling the subglacial environment with geostatistics
Abstract/Contents
- Abstract
- The conditions beneath glaciers and ice-sheets including the topography, hydrology, and geology are essential for understanding ice dynamics, interpreting ice-sheet history, and predicting ice-sheet retreat and sea-level-rise in response to a changing climate. Located in remote regions and overlain by several kilometers of ice, subglacial conditions are difficult to characterize at ice-sheet scales. In this thesis, I explore the use geostatistical simulation and machine learning methods to characterize subglacial hydrologic and geologic conditions and produce the first ensemble realizations of stochastically simulated subglacial topography. In Chapter 2 of this thesis, I consider the physical and geological controls on the sizes and locations of Antarctic subglacial lakes. In Chapter 3, I investigate uncertainty in subglacial water routing at Jakobshavn Glacier in Greenland. In Chapter 4, I provide subglacial geological estimates for the Amundsen Sea Embayment in West Antarctica.
