[Geoqus] GIA session @ EGU2013 in Vienna

[Holger Steffen]

(with apologies for multiple postings)

Dear colleagues,

Happy New Year!

The deadline (January 9th, 2013) for submitting an abstract to the General 
Assembly of EGU to be held in Vienna, Austria, 7-12 April, 2013, is 
approaching.

Bert Vermeersen, Markku Poutanen, Tom James, Willy Fjeldskaar, and myself are 
inviting you to submit your contribution to the interdisciplinary session on 
glacial isostatic adjustment (GIA): G3.1/CR3.9/GD1.4/TS1.5 Glacial Isostatic 
Adjustment, Mantle Viscosity and Ice Sheet Fluctuations.

Please note that we plan a special issue together with DynaQlim. Please 
consider this opportunity when submitting an abstract to this session.

Our keynote speaker is Erik Ivins.

We look forward to meet you in Vienna,

Bert, Holger, Markku, Tom and Willy

Glacial isostatic adjustment (GIA), the response of the Earth to past and 
present-day fluctuations of glaciers, ice caps, and ice sheets, generates large 
and measurable changes to sea level, crustal motion, especially the land 
uplift, and the Earth's gravitational field. Studies on GIA provide also 
valuable information on past history of ice masses and on Earth rheology. 
Furthermore, GIA contributes substantially to related mass-transport phenomena, 
such as present-day hydrological and oceanographic changes. In these cases, the 
GIA signal must be modelled and removed in order to isolate the other 
processes. Another area of interest is the understanding of GIA-induced 
earthquakes in conjunction with the determination of glacially induced faults.

Scientific investigations of GIA started in the early 18th century in 
Fennoscandia, and since then various data have been collected, e.g. relative 
sea-level (RSL), tide gauges records, leveling, GPS, absolute and relative 
gravity measurements, and nowadays also data from satellite missions such as 
GRACE. GIA modeling has undergone a huge improvement since its beginning. 
Nowadays with the computational power, 3D spherical models based on different 
techniques are mainly in use. Appropriate regional models also exist, which may 
allow the inclusion of crustal structures such as sedimentary basins and faults 
for selected special investigations such as post-glacially induced earthquakes.

In this session, we invite papers, which focus on GIA phenomena around the 
world and/or the usage of observations for determination of Earth's rheological 
parameters. We welcome contributions directly addressing observations, 
modelling of GIA and the inferences regarding glacial history and Earth 
rheology. In particular, applications of GRACE-gravity data and the 
uncertainties introduced by an imprecisely-known GIA response are of relevance 
to this session. This session is also a venue to present recent results of the 
Dynamics of Quaternary Climate (DynaQlim) project and of COST Action ES0701 
Improved Constraints on Models of GIA.

We plan a special issue together with DynaQlim. Please consider this
opportunity when submitting an abstract to this session. More information and 
instructions will be sent to those who have submitted an abstract in this 
session.

Our invited speaker will be Erik Ivins (JPL Pasadena, USA).
