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.
