The Parallel Ice Sheet Model pism0.7 is open source and capable of high resolution. It is widely adopted as a tool for doing science. Features include:

PISM Application of the Month

October 2016

Depth of water on the Antarctic continental shelf is one key factor determining the maximum possible contribution of ice shelf processes (calving and sub-shelf melting/freezing) to ice-sheet mass balance. This paper uses PISM to investigate how shelf-depth changes through geologic time might have affected Antarctic Ice Sheet (AIS) dynamics. Over-deepened, shallow, and intermediate versions of BEDMAP2 bathymetry were combined with unmodified land elevations. For climate forcing similiar to the last glacial cycle, a polar AIS surrounded by shallow and intermediate bathymetries experiences rapid grounding-line advance early during the transition from interglacial to glacial conditions. The corresponding increase in mass is primarily a result of lower calving fluxes from smaller-area ice shelves. In contrast, the currently over-deepened bathymetry in the same forcing generates the expected gradual advance of grounding lines.

Reminder for authors of PISM-using papers

Please acknowledge the funding that makes PISM possible, and which supports its continued maintenance and technical support. Include the sentence “Development of PISM is supported by NASA grants NNX13AM16G and NNX13AK27G.” in the Acknowledgments part of your paper.

If authors do this consistently then it will help to ensure continued funding of PISM!

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 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.
