The feasibility of imaging subglacial hydrology beneath ice streams with ground-based electromagnetics

Publikováno v: Journal of Glaciology, Vol 63, Pp 755-771 (2017)

Subglacial hydrologic systems in Antarctica and Greenland play a fundamental role in ice-sheet dynamics, yet critical aspects of these systems remain poorly understood due to a lack of observations. Ground-based electromagnetic (EM) geophysical metho

Uncertainty quantification for regularized inversion of electromagnetic geophysical data – Part II: application in 1-D and 2-D problems

Autor: Daniel Blatter, Matthias Morzfeld, Kerry Key, Steven Constable

Publikováno v: Geophysical Journal International. 231:1075-1095

SUMMARY This paper is Part II of a two-part series on a mathematical and computational framework for computing a meaningful uncertainty quantification (UQ) for regularized inversions of electromagnetic data. In Part I, we explained the theory behind

Uncertainty quantification for regularized inversion of electromagnetic geophysical data—Part I: motivation and theory

Autor: Daniel Blatter, Matthias Morzfeld, Kerry Key, Steven Constable

Publikováno v: Geophysical Journal International. 231:1057-1074

SUMMARY We present a method for computing a meaningful uncertainty quantification (UQ) for regularized inversion of electromagnetic (EM) geophysical data that combines the machineries of regularized inversion and Bayesian sampling with a ‘randomize

A dynamic saline groundwater system mapped beneath an Antarctic ice stream

Autor: Chloe D. Gustafson, Kerry Key, Matthew R. Siegfried, J. Paul Winberry, Helen A. Fricker, Ryan A. Venturelli, Alexander B. Michaud

Publikováno v: Science (New York, N.Y.). 376(6593)

Antarctica’s fast-flowing ice streams drain the ice sheet, with their velocity modulated by subglacial water systems. Current knowledge of these water systems is limited to the shallow portions near the ice-bed interface, but hypothesized deeper gr

Fluid Transport and Storage in the Cascadia Forearc inferred from Magnetotelluric Data

Autor: Kerry Key, Bo Yang, Paul A. Bedrosian, Blake Parris, Anna Kelbert, D. Livelybrooks, Adam Schultz, Gary D. Egbert

Subduction of hydrated oceanic lithosphere can carry water deep into the Earth, with important consequences for a range of tectonic and magmatic processes. Most fluid is released at relatively shallow depths in the forearc where it is thought to play
