Fall AGU Meeting, 3-7 December, 2012, in San Francisco We would like to ask you to consider submitting an abstract, (T031) on the theme of measuring the vertical motion of the Earth's surface on geological time scales. The goal of this session is not only to report new data from study areas but also to explore new methods and concepts and how such data can be integrated with various models (climate, tectonics etc). Invited Speakers Carmela Garzione (Rochester) Pratigya Polissar (Lamont-Doherty, Columbia) Session T031: Measuring the vertical motion of the Earth's surface on geological time scales Abstract: Measuring a critical, parameter such as the vertical motion of the Earth's surface remains problematic. Whilst advances have been made for direct measurements in real time and for short time scales much less progress has been made for studies that extend to geological time scales where the resolution is low. This is hindering fundamental research on the earth system. We invite contributions from all areas of science relevant to understanding and solving this challenging problem including analytical specialists, numerical modelers and theorists, geologists and geomorphologists. What new proxies are on the horizon? Can we improve resolution of isotope and biomarker methods? Can thermochronometry constrain surface uplift? The deadline for all submissions is 8 August 23:59 EDT/03:59 +1 GMT.
