A 2-year Post-Doctoral Research opportunity and the University of Alaska Fairbanks:

The Relationship between Climate and Ice Rheology at Dome C, East Antarctica
University of Alaska Fairbanks

This post-doctoral researcher will join a team of researchers from the University of Alaska Fairbanks and collaborators from Laboratoire de Glaciologie et Geophysique de l'Environnement (LGGE), Grenoble, France to study the relationship between fabric and climate for the ice near the EPICA Come C ice core site, East Antarctica.  Observations from ice cores have shown that the fabric and grain size are correlated with glacial/interglacial surface conditions. Because ice deformation is sensitive to the orientation of crystals, ice flow patterns are sensitive to fabric and this creates positive feedbacks within the ice that results in strong spatial gradients in fabric and grain size with depth in an ice sheet. The goal of this project is to understand the processes that control the climate-fabric relationship and explore possibilities of extracting past climate information directly from fabric data.

The primary activities of this post-doc will be to:

- collect field and laboratory measurements of ice fabric and related physical properties using measurements of sonic velocity in the borehole and on ice,

- work with team members to use models of ice flow and the evolution of fabric to capture the key processes that lead to observed fabrics at depth in the ice,

- use the model and observations together using inverse techniques to extract past climate information from fabric data. 


The position is for 2 years and will be located within the glaciology research group at the University of Alaska Fairbanks, which consists of approximately 15 researchers, post-docs, and graduate students conducting a broad spectrum of ongoing glaciology research and provides a great opportunity for the post doc to broaden his or her knowledge of glaciology, related research fields, and research techniques. 

STARTING DATE is negotiable, but ideally around September 1, 2010.

Field work at Dome C, East Antarctica will take place in December 2010 and January 2011.

The primary supervisor for this positions is Dr. Erin Pettit.

REVIEW OF APPLICATIONS will begin on April 15, open until filled. Applicants much have a Ph.D. in Geophysics or related field by the start date. Highly motivated, able to work independently, and learn new techniques. The applicant must be willing to conduct field and laboratory work and also have some experience or knowledge of ice flow modeling.
