A one-day workshop to discuss the design and implementation of oceanic forcing for the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6). The aim of ISMIP6 is to improve projections of sea level via simulation of the evolution of the Greenland and Antarctic ice sheets under a changing climate, and to quantify associated uncertainties in climate forcing and the response of ice sheets.  

The aim of this workshop is to create a roadmap for translating the CMIP6 open-ocean forcing into forcing to which the ice sheet can respond. Questions  that are to be explored include: How does large-scale ocean signal get into shallow-shelf waters? What processes affect the migration of the coastal water towards the ice? What are the mechanics of the way ice and water interact?

Specific goals of the workshop are to:

  • Review existing parameterizations used in the ice sheet community for melt from under ice shelves, melt from termini of outlet glacier, and calving.
  • Obtain guidance from oceanographers on desirable properties of melt and calving parameterizations.
  • Identify datasets that can be used to test, validate, or constrain melt and calving parameterizations.  
  • Discuss CMIP5 ocean models in the polar regions, and how to evaluate CMIP6 models.

This scoping meeting will set the direction for the standalone ice sheet component of ISMIP6, and lay the foundation for a more detailed evaluation of CMIP6 models and generation of oceanic forcing in late 2017.

Since the workshop cannot host more than ~30 people, we possibly need to limit the number of participants. Expressions of interest to attend are solicited from the international community at this time (ideally one paragraph, one-page maximum). These should be sent to This email address is being protected from spambots.

Participants wishing to apply towards travel support (~one hotel night) from CliC should indicate this in the expression of interest email.  The ISMIP6 steering committee will select participants to represent the glaciological, oceanographic, and climate research communities. Attendees will be notified in early October 2016.

ISMIP6 is a targeted activity of the Climate and Cryosphere (CliC) program of the World Climate Research Program (WCRP), and has been endorsed by the Climate Model Intercomparison Project-Phase 6 (CMIP6). More information can be found at http://www.climate-cryosphere.org/activities/targeted/ismip6
