Dear Colleagues,

only a few days are left to submit abstracts for the 2007 Joint Assembly 
of AGU and a number of other Earth Science organizations to be held on 
22-25 May 2007 in Acapulco, Mexico. Therefore, we would like to bring to 
  your attention Session G07: "The Global Geodetic Observing System: 
Providing Constraints on Mass Movements in the Earth System" (see 
http://www.agu.org/meetings/ja07/?content=search&show=detail&sessid=207).

Changes in the Earth's shape, gravity field and rotation are inherently 
related to mass transport in the fluid envelop of the Earth system and 
the interior of the solid Earth. Traditionally, observations of these 
changes have been interpreted independently and inverted for mass 
changes particularly in the hydrosphere. Recently, attempts have been 
made to interpret observations of two of the quantities simultaneously. 
However, at the accuracy level of 1 parts per billion or better, 
interactions between the Earth components (atmosphere, ocean, and solid 
Earth) as well as the three quantities (e.g. coupling of rotation and 
deformation) are relevant and an integrated theory consistent across the 
three geodetic quantities is required in order to process the 
observations, model the observed changes, and invert for model 
parameters describing the mass transport.

We invite papers addressing progress towards integrated data analysis, 
modeling and interpretation of observations of the changes in Earth's 
shape, gravity field, and rotation on temporal scales ranging from free 
oscillations, Earth tides, meteorological and climatological processes 
to glacial loading, and on spatial scales from local to global studies. 
Aspects of particular interest are the combined processing of 
observations (e.g. gravity and displacements), improved forward modeling 
with Earth system models, and joint inversion of observations (e.g. 
displacements and rotation changes). If you are working in these broad 
fields then we are looking forward to hear about your results. Abstract 
submission deadline is March 1, 2007. Information on abstract submission 
is available at http://www.agu.org/meetings/ja07/?content=program

We are looking forward to seeing you in Acapulco.
