IGCP 653 theme session at Geological Society of America Meeting in Seattle

Dear All,

We are convening a topical session entitled “The onset of the Great Ordovician Biodiversity Event (GOBE): Testing Hypotheses with Diverse Data Sets” at the 2017 Geological Society of America conference. The conference will be held 22-25 October in Seattle, Washington. For this session (T60) we invite contributions testing hypotheses concerning the Late Cambrian to Ordovician biotic and abiotic drivers of marine diversification in all contexts. We welcome diverse data sets illuminate the timing, initiating conditions, stratigraphy, and paleontology of this significant event in Earth’s history.  Our invited speakers include Katherine Marenco (Byrn Mawr University), Seth Young (Florida State), and Jesse Carlucci (Midwestern State University).

This session is a regional meeting of IGCP Project 653, The Onset of the Great Ordovician Biodiverisifcation Event http://www.igcp653.org. The goal of this project is to better constrain the triggering causes leading to establishment of modern marine ecosystems and also to the identification of the reasons of the first collapse of these environments during the Late Ordovician mass extinction. Our GSA session will be the first opportunity for project participants to meet in North America.

The goal of this session is to bring together geoscientists from a diverse set of fields including palaeontology, sedimentology, stratigraphy, geochemistry, palaeooceanography, palaeoclimatology to present new research bearing on the initiating factors and timing of the GOBE.  By assembling a diverse set of speakers and topics, it is our hope that all participants will develop additional capacity to consider and ultimately integrate additional data streams within analyses and interpretations of their own data.

If you have a current project that fits the scope of our session we hope that you will consider submitting an abstract. Abstract submission is open now and will close on August 1st.  For more information about the GSA meeting visit: http://community.geosociety.org/gsa2017/home

Please contact either of us if you have any questions and forward this announcement to others who may be interested in contributing.
