The detailed description follows below. The CGU/AGU/SEG Joint Assembly will be held between May 17 and 21 in Montreal, Canada. Abstracts are accepted not later than February 12. (postal), respectively February 19, 23:59 (electronic submission) For further information please visit the AGU home page http://www.agu.org The online abstract submission form is available on the AGU Web site at http://submissions5.agu.org/submission/entrance.asp We would be grateful if you could help us to extend this message to additional potential contributors within your own network of contacts. With best regards from the conveners, and hoping to see you at the meeting Hans-Georg Scherneck, Thomas James, Isabella Velicogna, Joe Henton **) G03 - Observations of Glacial Isostatic Adjustment and Contemporary Ice-Ocean-Mantle Mass Redistribution The response of the Earth to past and present-day ice mass change, and the ensuing redistribution of meltwater, on scales ranging from local to global, is the focus of this session. Reports of new high-precision geodetic observations that complement traditional relative sea-level, lake shoreline tilt, and water gauge observations are especially welcomed. Satellite laser ranging (SLR) provides estimates of the secular change of low-degree gravitational harmonic coefficients, indicating global surface and mantle mass redistribution. SLR observations will be complemented by the GRACE and GOCE satellite missions, which will give gravitational changes at much higher spatial resolutions, but over a shorter period of time. Both kinds of satellite observations are augmented by ground-based point gravity observations from relative, absolute, and cryogenic gravimeters. Current glacial change is the focus of ICESAT/GLAS, and global sea-level change has been accurately measured by TOPEX/POSEIDON. Measurements based on ranging principles, such as GPS and VLBI, provide high-precision measurements of three-dimensional crustal deformation. Papers that combine observations from a number of techniques to better constrain the linked ice-ocean-Earth system are of particular interest. **) Conveners Hans-Georg Scherneck, Chalmers, Göteborg, Sweden Thomas James, Natural Resources Canada, Sydney, BC, Canada, Isabella Velicogna, CIRES, Boulder, Co., USA, Joe Henton, NRCan, Sydney, BC, Canada, Index terms 1200 Geodesy and Gravity 1208 Crustal movements--intraplate 1243 Space geodetic surveys 1234 Regional and global gravity anomalies and Earth structure 4556 Sea level variations *) G02 Pleistocene ice-mass change, displacement and gravity change, and thir interpretation with 3-D earth models -- Med vänliga hälsningar ----- With best regards yours / A \ Hans-Georg | / \ | ---------------------+---------------------------------- \ / Telephone: | Hans-Georg Scherneck ----- +46 31 772 5556 | Onsala Space Observatory | | Telefax: | Chalmers University of Technology / \ +46 31 772 5590 | S-439 92 Onsala, Sweden ---------------- E-Mail: | ftp://gere.oso.chalmers.se/pub /===\ ,===//===\ hgs@oso.chalmers.se | http://www.oso.chalmers.se/~hgs// /`===,/ / ---------------------+-------------------------------- \===//===' \===/ Please do not reply directly to this message, but send comments and suggestions to IDS.central.bureau@cls.fr
