[Geoqus] GIA session @ EGU2014 in Vienna

[Holger Steffen]

(with apologies for multiple postings)

Dear colleagues,

Markku Poutanen, Willy Fjeldskaar, Wouter van der Wal and myself are inviting 
you to submit your contribution to the interdisciplinary session on glacial 
isostatic adjustment (GIA) "G3.1/CL2.15/CR1.7/GD8.4/GM9.7/TS4.7
Observations and modelling of Glacial Isostatic Adjustment and related 
processes" at the General Assembly of the EGU to be held in Vienna, Austria, 27 
April - 2 May, 2014.

The deadline for submitting an abstract is 16 January 2014, but for students 
applying for support it is approaching: 29 November 2013!

Our keynote speakers are Jerry Mitrovica (Harvard) and Daniel Stoddart (Lundin 
Petroleum).

We look forward to meet you in Vienna,

Markku, Willy, Wouter, and Holger

Glacial isostatic adjustment (GIA) is the response of the Earth to past and 
present-day fluctuations of glaciers, ice caps, and ice sheets, generating 
large and measurable changes to sea level, horizontal and vertical crustal 
motion, and the Earth's gravitational field. It also influences Earth’s 
rotation and stress field.

Studies on GIA provide valuable information on past glaciation history and on 
Earth rheology, and help in the determination of past, present and future 
sea-level changes. They are based on various data, e.g. relative sea-level 
(RSL), tide gauges records, levelling, GPS, satellite altimetry, terrestrial 
(absolute and relative) and space-borne gravity measurements as well as on 
sophisticated GIA modelling. GIA also contributes substantially to related 
mass-transport phenomena, such as present-day hydrological and oceanographic 
changes. In these cases, the GIA signal must be thoroughly modelled and removed 
in order to isolate the other processes. Other areas of interest are the 
understanding of GIA-induced earthquakes in conjunction with the determination 
of glacially induced faults or the influence of GIA on the remigration of oil 
and gas in adjacent areas.

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, Earth rheology, 
and environmental changes (e.g. sea-level change, palaeohydrology, 
palaeogeography). In particular, applications of GRACE-gravity data and the 
uncertainties introduced by an imprecisely-known GIA response are of relevance 
to this session. Furthermore, we welcome new modelling developments such as 
inclusion of crustal/lithospheric structures (sedimentary basins, faults, 
subduction zones) and mantle rheologies. This session is also a venue to 
present recent results of the Dynamics of Quaternary Climate (DynaQlim) project 
and to introduce the new ICDP project “Drillling Active Faults in Northern 
Europe” (DAFNE).
