Forwarded from CLIMLIST...

Three funded PhD positions in the Glacial Dynamics Group at the
Department of Physics and Physical Oceanography, Memorial University of
Newfoundland, are currently available: (Colleagues are asked to bring
this to the attention of competent students who might be interested in
these projects.)

1) Coupled ice and climate system modelling with a focus on high
frequency variability/instability. We know the climate system jumped
around a lot during the last glacial cycle, but models have yet to fully
capture such climate system variability. This project will focus on the
well documented Heinrich event 1 to Younger Dryas interval. It will
examine sensitivity of climate response to both meltwater injection
chronologies and the numerical representation of relevant processes.

This project also includes the following sub-project: Introduction of
sub-grid stochastic parametrizations to improve the representation of
turbulent processes in low resolution GCMs for long time-scale
modelling. Results will be compared against those of higher resolution

2) Analysis of high-frequency feedbacks in the glacial system between:
ice streaming - basal hydrology - grounding line displacement - calving.
This project will quantify bounds on potential instabilities in the
system for the Antarctic ice sheet. The introduction of stochastic
components will be considered. It will bound Meltwater Pulse-1a
contributions from Antarctica as well as potential future contributions
to "abrupt" sealevel change.

This project will also entail calibration of the basal hydrology
component of the MUN glacial systems model.

3) Inversion of present-day North American sediment distribution. This
PhD project will invert the present-day distribution of glacially
transported sediments over North America to infer the history of
sediment production and transport. It will build on recently completed
work on erosion and sediment transport model development
(<>). It will also
evaluate the extent to which the existing sediment distribution can be
used to further constrain past glacial evolution and will test the
regolith hypothesis for the origin of the mid-Pleistocene transition.

This project will further examine the impact of fully coupled subglacial
hydrology, sediment production/transport/deposition, and basal drag
physics on both long-term ice-sheet evolution and high-frequency ice
sheet dynamics, in collaboration with project 2 above.

Applications are invited from candidates with an interest in glaciology,
numerical modelling, continuum mechanics, climate modelling, and/or
Earth systems science. Applicants must have achieved a BSc or Masters's
degree in physics, geophysics, applied mathematics, meteorology,
oceanography, or closely related areas. Applicants must also be
interested in working in a collaborative environment on computationally
intensive projects.

Required skills:
-Some experience in using FORTRAN or C, and analysis packages such as
-Knowledge of general physics (even better with understanding of
fluid dynamics and/or atmospheric/ocean physics)
-Fluency in relevant maths (linear/matrix algebra and differential
equations; statistics is very advantageous)

The group has a dedicated 540 core cluster (to be doubled in 2014) and
access to further computational resources through ACEnet.

Associated benefit: the spectacular natural environment of Newfoundland,
