Postdoctoral opportunities in glaciology at Iowa State University

Neal R Iverson

Dear Colleagues:

 

This is a reminder of postdoctoral opportunities in glaciology in the Department of Geological and Atmospheric Sciences at Iowa State University (see below). Please forward to anyone who might be interested.

 

Many thanks,

 

Neal

Experimental deformation of temperate ice. A rotary device will be used to study relationships between the water content of temperate ice and its rheology, texture, and permeability, with emphasis on assessing deformation resistance and water flow within the margins of Antarctic ice streams.  Experimental experience in glaciology, in rock physics, or in a related field is required.  These experiments will be used to help develop a two-phase theory of temperate ice flow applicable to ice-stream dynamics and will be part of an NSF-Geo/UK-NERC collaborative project (with Luke Zoet, UW-Madison, and Rich Katz and Ian Hewitt, Oxford). The postdoctoral appointment will be for 2.5 years, with a flexible starting date in the summer or fall of 2017.

 

Modeling of glacier sliding. The finite-element code, Elmer/Ice, will be used to model ice flow in the boundary layer where glacier sliding is accommodated. Sliding rules will be developed that include the effects of 3D bed topography, ice-bed separation, debris-bed friction, and shearing subglacial till, with the goal of evaluating the range of constitutive behavior possible during sliding.  Experience with numerical modeling of ice flow is required, and experience with Elmer/Ice is desirable. Field measurements of the topography of exposed glacier beds with a terrestrial laser scanner and laboratory measurements of debris-bed friction will be used in the modeling.  This project is collaborative with Luke Zoet (UW-Madison).  The appointment will be for two years with a flexible starting date in 2018.

 

Applications should be sent electronically (application letter, CV, and names and contact information for at least three referees) to Neal Iverson ([hidden email]). Review of applications will begin on March 10, 2017, and will continue until the positions are filled.
