Time's running short to submit an abstract to the ESP2meeting! Make sure you do if the following session interests you: Earth System Processes 2 www.geosociety.org/meetings/esp2/ Geological Society of America Calgary, 8-11 August 2005 Call for papers: abstract deadline 26 April 2005 Scientific session T22. Soil Organic Matter: Cycling, Transport, and Ocean-Climate Interaction. Convenors: David Manning, University of Newcastle; Thomas Wagner, University of Bremen; Lavern Stasiuk, Geological Survey of Canada, Calgary. This session addresses the hypothesis that terrestrial (soil) organic matter is an important, yet hardly constrained, contributor to marine sediments that provides valuable information on terrestrial climate at the source, modes of transport, and diagenetic mechanisms controlling the formation of geological signals stored at the sea floor. We are keen to receive offers of papers from those interested in terrestrial and marine processes and the affects these have on the preservation/degradation, transport and deposition of biogenic material. We expect the session to cover soil processes, marine processes and links between the two. Keynote speakers: Gabriel Bowen (University of Utah) Topic: Carbon isotope and paleosol records document the effect of a major carbon cycle perturbation at 55 Ma on terrestrial plant and soil systems, which couple with a huge fluctuation in the state of the marine carbonate system and indicate close linkage of hydrologic and geochemical systems during rapid climate change. Helen Talbot with Paul Farrimond and Mark Sugden (University of Newcastle) Topic: Molecular tracers of soil inputs to aquatic sediments include a recently identified novel group of bacterial hopanoids found to be present in all soils studied to date. These compounds can be traced into the aquatic environment, providing evidence of fluxes characteristic of specific terrestrial environments.
