Numerical simulations of the Cordilleran ice sheet through the last glacial cycle

journal: The Cryosphere

This paper uses PISM, calibrated against field-based evidence, to reconstruct the Cordilleran ice sheet's history through the last glacial cycle. Until now, geological studies of this major North American ice sheet have lacked ice-sheet-wide spatial reconstructions.

Simulations are driven by time-dependent temperature offsets from six proxy records located around the globe. Although model response to evolving climate forcing is variable, all simulations produce two major glaciations during marine oxygen isotope stages 4 (62.2–56.9 ka) and 2 (23.2–16.9 ka). The timing of glaciation is better reproduced using temperature reconstructions from Greenland and Antarctic ice cores than from regional oceanic sediment cores. During most of the cycle the modelled ice cover is discontinuous and restricted to high mountain areas. However, a central ice dome in the Skeena Mountains persists throughout, and it hosts the last remains of Cordilleran ice into the middle Holocene (6.7 ka).

PostDoc in ice sheet and climate modelling at AWI Bremerhaven, Germany

The Paleoclimate Dynamics section at Alfred-Wegener-Institut invites applications for a position as a

PostDoc scientist

with a background in ice sheet or climate modelling for the DFG-project “Global sea level change since the Mid Holocene” (SPP 1889).

Background and tasks:

The aim of this project is to study the evolution of polar ice sheets of the last 6000 years and to estimate the role of climate – ice sheet interactions. Combining climate and ice sheet simulations of different resolution, the project particularly focusses on the ice sheets' mass balance and on ice shelf – ocean interactions under natural and anthropogenic climate change.

The postdoc’s duties will include set-up, supervision, and analysis of climate and ice sheet (PISM) simulations as well as publication in peer-reviewed journals.

Requirements:

The successful candidate should have a PhD in glaciology, atmospheric sciences, oceanography or related sciences and should have a background in either ice sheet or climate modelling.

The position is limited to 3 years, starting August 1st, 2016 or later. The salary will be paid in accordance with the German Tarifvertrag des öffentlichen Dienstes (TVöD Bund), salary level 13. The place of employment will be Bremerhaven.

PISM stable/dev and PETSc 3.7

PETSc 3.7 was released on April 25, 2016. We are currently working on making PISM compatible with PETSc 3.7 and will announce it here as soon as possible.

In the meantime, please install petsc 3.6.4 from here. PISM version 0.7 (stable0.7 branch) works with any PETSc 3.5.X and higher.

PISM team

PISM is jointly developed at the University of Alaska, Fairbanks (UAF) and the Potsdam Institute for Climate Impact Research (PIK). For more about the team see the UAF Developers and PIK Developers pages.

UAF developers, who are in the Glaciers Group at the GI, are supported by NASA's Modeling, Analysis, and Prediction and Cryospheric Sciences Programs (grants NAG5-11371, NNX09AJ38C, NNX13AM16G, NNX13AK27G) and by the Arctic Region Supercomputing Center.
