International Association of Geodesy  International Symposium: 
*Reconciling Observations and Models of Elastic and Viscoelastic Deformation due to Ice Mass Change*
30 May - 2 June 2013, Ilulissat, Greenland http://www.dtu.dk/subsites/iag.aspx

Abstracts are invited for presentation at the International Symposium on Reconciling Observations and Models of Elastic and Viscoelastic Deformation due to Ice Mass Change, deadline 15th February 2013.

Knowledge of present-day changes in the ice sheets and glaciers are critical to partitioning the individual sources of the well-observed global sea-level change. Similarly, knowledge of past changes is required to advance understanding of the paleo sea level budget and also provide the context for present-day changes. Both past and present changes in the mass balance of the Earth's glaciers and ice caps induce present-day deformation of the solid Earth on a range of spatial scales, from the very local to global. Observations of present-day changes in Earth's shape, gravity field and rotation are therefore sensitive to changes in ice load over a large range of time-scales.

Particularly relevant to this are data from GRACE, and proposed follow-on missions, which require accurate removal of glacial isostatic adjustment (GIA) to obtain present-day ice mass balance. Likewise, the increasing network of geodetic measurements, especially continuous GPS, in presently, or formerly, glaciated regions may validate, or be assimilated into, models of GIA and/or constrain models of present-day ice mass change through measurements of elastic rebound. Notable here are the International Polar Year POLENET networks of Greenland and Antarctica. It is impossible to interpret data or validate or improve models of the kind mentioned here without close interaction between a wide group of geophysicists. The symposium will focus on enabling this interaction and creating new collaborations through the discussion of the results of scientific studies focused on visco-elastic deformation of the solid Earth due to ice (un)loading.

This symposium seeks to bring together those working on observation and modelling of cryospheric change and solid earth response to further our understanding of the Earth system. These include, but are not limited to, the fields of GIA modelling, ice sheet reconstructions, geodesy (changes in deformation, gravity and Earth rotation), glaciology and seismology. The principal interest is in discussing existing, and initiating new, studies at the interface between these various disciplines. We also seek to maximise the use of existing and future datasets to provide the most robust tests/constraints on models.

- Reconciling models and observations of GIA

Travel support
Thanks to generous funding from the SCAR SERCE programme, there are funds available to part-support a limited number of attendees. These will be awarded after the abstract submission deadline and preference will be given to early stage researchers and scientists from a SCAR nation with an emerging Antarctic programs. Details will be posted soon on the symposium website. Further funding has been provided by IUGG and NASA, and hopefully NSF. Please be aware that early stage researchers may also apply for an IAG travel award (http://iag.dgfi.badw.de/fileadmin/handbook/1-8-iag-travel-award.pdf
with applications needed 3 months before the meeting).

Some important deadlines
