***************************************************************** From: Bruce P. Luyendyk <luyendyk@xxxxxxxxxxxxx> ***************************************************************** I want to draw your attention to a special session for the upcoming Fall 2007 AGU, T16, The Mesozoic Pacific: Plate Tectonics, Volcanism, Paleoceanography, and the Geomagnetic Field. I would like to encourage you to submit a presentation to this session. Abstract submittal deadline (electronic) is September 6, 2007. This session will present the latest advances in understanding the evolution of the Mesozoic Pacific, including its plate tectonic history, polar wandering path, the record of the geomagnetic field locked into its crust, the origin of its oceanic plateaus and seamount chains, and paleoceanographic record. The geologic evolution of the Mesozoic Pacific exerted a major role in the development of the ocean/atmosphere system, resulting in some of the most dramatic environmental episodes in Earth history. Emplacement of giant plateaus may be related to excess CO2, global warming, ocean acidification and nutrification and, ultimately, global anoxia. Accelerations in evolutionary rates in many groups may correlate with pulses in ocean crust production, particularly during the mid-Cretaceous, suggesting that endogenous processes might have directed the development of life of the planet. The Mesozoic crust of the Pacific basin represents important aspects of geomagnetic field behavior, ranging from periods of rapid reversals to no reversals for long intervals, which bear on the underlying mechanism of the geodynamo. Contributions by Roger L. Larson demonstrated many unique aspects of Mesozoic ocean geology, including rapid seafloor spreading, tectonic reorganizations, and large igneous provinces, and geomagnetic field behavior. This session invites contributions that describe recent advances in our understanding of the Mesozoic ocean basins focusing on the Pacific, including research on geology, tectonics, volcanism, oceanography, geomagnetism, and the geologic time scale. Wide ranges of interdisciplinary studies are welcome to improve our knowledge of processes and understanding of causal links between the geosphere and the biosphere. I hope that you will participate in this important session. I apologize if you have received multiple announcements, as several of my colleagues are sending these out. Please forward this email to others that you feel may be interested in this exciting special session.
