@article {119, title = {The evolution of crystal fabric in ice sheets and its link to climate history}, journal = {Journal of Glaciology}, volume = {59}, year = {2013}, pages = {357-373}, abstract = {The evolution of preferred crystal-orientation fabrics is strongly sensitive to the initial fabric and texture. A perturbation in climate can induce variations in fabric and texture in the firn. Feedbacks between fabric evolution and ice deformation can enhance these variations through time and depth in an ice sheet. We model the evolution of fabric under vertical uniaxial compression and pure shear regimes typical of ice divides. Using an analytic anisotropic flow law applied to an aggregate of distinct ice crystals, the model evolves the fabric and includes parameterizations of crystal growth, polygonization and migration recrystallization. Stress and temperature history drive the fabric evolution. Using this model, we explore the evolution of a subtle variation in near-surface fabric using both constant applied stress and a stress-temperature history based on data from Taylor Dome, East Antarctica. Our model suggests that a subtle variation in fabric caused by climate perturbations will be preserved through time and depth in an ice sheet. The stress history and polygonization rate primarily control the magnitude of the preserved climate signal. These results offer the possibility of extracting information about past climate directly from ice fabrics.}, doi = {10.3189/2013JoG12J159}, url = {http://glacierstest.gi.alaska.edu/sites/default/files/bibfiles/t12J159.pdf}, author = {Joseph H Kennedy and Erin C Pettit and Di Prinzio, Carlos L} } @article {zagorodnov2012borehole, title = {Borehole temperatures reveal details of 20th century warming at Bruce Plateau, Antarctic Peninsula}, journal = {The Cryosphere}, volume = {6}, number = {3}, year = {2012}, pages = {675{\textendash}686}, publisher = {Copernicus GmbH}, author = {Zagorodnov, V and Nagornov, O and Scambos, TA and Muto, A and Mosley-Thompson, E and Erin C Pettit and Tyuflin, S} } @article {gusmeroli2012crystal, title = {The crystal fabric of ice from full-waveform borehole sonic logging}, journal = {Journal of Geophysical Research: Earth Surface (2003{\textendash}2012)}, volume = {117}, number = {F3}, year = {2012}, publisher = {Wiley Online Library}, author = {Alessio Gusmeroli and Erin C Pettit and Joseph H Kennedy and Ritz, Catherine} } @article {pettit2012listening, title = {Listening to Glaciers: Passive Hydroacoustics Near Marine-Terminating Glaciers}, journal = {Oceanography}, volume = {25}, year = {2012}, publisher = {The Oceanography Society (TOS)}, author = {Erin C Pettit and Nystuen, Jeffrey A and O{\textquoteright}Neel, Shad} } @article {pettit2012passive, title = {Passive underwater acoustic evolution of a calving event}, journal = {Annals of Glaciology}, volume = {53}, number = {60}, year = {2012}, pages = {113}, author = {Erin C Pettit} } @article {carmichael2012seismic, title = {Seismic multiplet response triggered by melt at Blood Falls, Taylor Glacier, Antarctica}, journal = {Journal of Geophysical Research: Earth Surface (2003{\textendash}2012)}, volume = {117}, number = {F3}, year = {2012}, author = {Carmichael, Joshua D and Erin C Pettit and Hoffman, Matt and Fountain, Andrew and Hallet, Bernard} } @article {pettit2011crossover, title = {The crossover stress, anisotropy and the ice flow law at Siple Dome, West Antarctica}, journal = {Journal of Glaciology}, volume = {57}, number = {201}, year = {2011}, pages = {39{\textendash}52}, publisher = {International Glaciological Society}, author = {Erin C Pettit and Waddington, Edwin D and Harrison, William D and Thorsteinsson, Throstur and Elsberg, Daniel and Morack, John and Zumberge, Mark A} } @article {69, title = {From ice-shelf tributary to tidewater glacier: continued rapid recession, acceleration and thinning of Rohss Glacier following the 1995 collapse of the Prince Gustav Ice Shelf, Antarctic Peninsula}, journal = {Journal of Glaciology}, volume = {57}, year = {2011}, pages = {397{\textendash}406}, doi = {10.3189/002214311796905578}, url = {http://openurl.ingenta.com/content/xref?genre=article\&issn=0022-1430\&volume=57\&issue=203\&spage=397}, author = {Glasser, NF and Scambos, TA and Bohlander, J. and Martin Truffer and Erin C Pettit and Davies, BJ} } @article {38, title = {Implications for the dynamic health of a glacier from comparison of conventional and reference-surface balances}, journal = {Annals of Glaciology}, volume = {50}, year = {2009}, pages = {25{\textendash}30}, author = {Harrison, W. and Cox, LH and Regine Hock and March, RS and Erin C Pettit} } @article {pettit2007role, title = {The role of crystal fabric in flow near an ice divide}, journal = {Journal of Glaciology}, volume = {53}, number = {181}, year = {2007}, pages = {277{\textendash}288}, publisher = {International Glaciological Society}, author = {Erin C Pettit and Thorsteinsson, Throstur and Jacobson, H Paul and Waddington, Edwin D} } @article {pettit2006ice, title = {Ice Flow at Low Deviatoric Stress: Siple Dome, West Antarctica}, journal = {Glacier Science and Environmental Change}, year = {2006}, pages = {300{\textendash}303}, publisher = {Wiley Online Library}, author = {Erin C Pettit} } @article {conway2005candidate, title = {Candidate drill site near the Ross-Amundsen ice divide, West Antarctica}, journal = {DRAFT, Mar}, year = {2005}, author = {Conway, H and Neumann, TA and Stephen F.
