The 2008 Joint Assembly - a partnership among AGU, AAGG, CIGMEX, GS, MSA, SBGf, SEG, SPD/AAS and UMEC.
Pre-registration deadline: 18 April 2008
A session of interest to InterRidge:
T02 Thermo-tectonic Models of Oceanic Lithosphere and the problem of Hydrothermal Circulation - A New Look
Conveners: Anne Hofmeister (Washington University, hofmeist@wustl.edu) and Valiya M. Hamza (Observatório Nacional - Brazil, hamza@on.br)
Understanding the thermophysical process of forming oceanic lithosphere at mid-ocean ridge pertains to plate tectonics and mantle convection, as well as to mechanisms of heat loss by the Earth. For the last 40 years, formation of the ocean lithosphere has been described using 1-dimensional vertical cooling models and such results are used to provide estimates of the global power. The diverse problems and large uncertainties associated with force-fitting these 1-d models to the 3-d lithosphere have recently been discussed in the literature, and have lead to new, substantially reduced estimates for the overall heat loss by the Earth. This session calls for papers on alternative models or measurements describing the heat flux, bathymetry, and temperature profiles of the oceanic lithosphere, locally and globally, as well as for papers that explore the implications of low global power for the Earth.
