Development of a Community Ice Sheet Model
National Science Foundation Grant NSF-IPY 0632161 “IPY: Collaborative Research: Development of a Community Ice Sheet Model with Specific Applications to Abrupt Change in the Amundsen Sea Embayment” Primary Investigator Jesse Johnson Co-investigators: Christina Hulbe, Joel Henry, Martin L. Barett, Slawek Tulaczyk, Dacian Deascu, William Robertson, and Cheryl Seals. This collaborative research effort is to carry out novel predictive modeling experiments on the Amundsen Sea Embayment region of Antarctica. Specifically, we seek to understand how interactions between basal processes and ice sheet dynamics can result in abrupt reconfigurations of ice-sheets, and how those reconfigurations impact other Earth systems, such as atmospheres and oceans. The proposed research is distinctive in that we recognize that advancement of ice-sheet modeling is dependent upon appropriate advances in outreach and software design. As such we have assembled a team of glaciologists (Johnson, Hulbe, Tulaczyk), software engineers (Henry, Barrett), a numerical analyst (Daescu), and education/human computer interaction (Seals, Robertson). Work on this grant is in it’s twenty second month and thus far has produced 4 peer reviewed manuscripts, 1 conference paper, 1 conference presentation, 3 invited talks, and 3 master’s thesis completed.
The broader goal of the research is to increase participation in ice sheet modeling by improving the community's capacity to
- access and utilize the present generation of ice sheet models.
- improve the quality of ice sheet models both in terms of the scientific merit of the modeling approach and the quality of the underlying software.
- understand the outcome of ice sheet modeling experiments.
