Shum, Hans-Peter Plag, Markus Rothacher and I are convening session G1 on ”The Global Geodetic Observing System: Providing Critical Observations of the Oceans”. The description of the session is given below. On behalf of the conveners I would like to draw your attention to this session and encourage you to participate in it. We are developing a rich session that will explore the use of geodetic observations to gain greater understanding of the oceans. We hope that you will be able to join us in Vienna for this exciting session. More information about the 2010 General Assembly of the EGU can be obtained from its web site at Please note that the deadline for submitting abstracts is 18 January 2010. Hope to see you in Vienna! Best regards, Richard Gross, C.K. Shum, Hans-Peter Plag, Markus Rothacher ................................. G1: The Global Geodetic Observing System: Providing Critical Observations of the Oceans The tools of geodesy have the potential to transform the ocean observing system. Geodetic observations are unique in the way that they produce accurate, quantitative, and integrated observations of gravity, ocean circulation, sea surface height, ocean bottom pressure, and mass exchanges among the ocean, atmosphere, cryosphere, and land. Geodetic observations have made fundamental contributions to monitoring and understanding physical ocean processes. In particular, geodesy is the basic technique to enable determination of an accurate geoid model, allowing for the determination of absolute surface geostrophic currents, which are necessary to quantify heat transport of the ocean. The present geodetic satellites can measure total sea level and its mass component, both of which are vital for understanding global climate change. Continuation of current satellite missions and the development of new geodetic technologies can be expected to further support monitoring of the ocean. IAG´s Global Geodetic Observing System (GGOS) provides the means for integrating the geodetic techniques that monitor Earth´s time- variable surface geometry (including ocean and ice surfaces), gravity field, and rotation into a consistent system for measuring ocean surface topography, ocean currents, ocean mass, and ocean volume changes. This system depends on both globally coordinated ground- based networks of tracking stations as well as an uninterrupted series of satellite missions. This session will be a forum for discussing the critical oceanographic parameters currently observed by geodetic observational systems, and the requirements to continue such measurements. Richard S.
