Subject: Call for papers: AGU session on Variability in Ocean Interior Circulation and Biogeochemistry
We would like to invite you to participate in the following session at the American Geophysical Union 2006 Fall Meeting in San Francisco:
Variability in Ocean Interior Circulation and Biogeochemistry: Repeat Hydrography and Modeling Studies
( http://www.agu.org/meetings/fm06/?content=search&show=detail&sessid=63 )
We are convinced this will be a really exciting session, and we look forward to seeing you there!

OS04: Variability in Ocean Interior Circulation and Biogeochemistry: Repeat Hydrography and Modeling Studies
Repeated hydrographic sections of all ocean basins have revealed substantial variability in physical and biogeochemical quantities, especially in thermocline waters. These water masses are uniquely suited to help advance our understanding of physical-biogeochemical processes and interactions as they tend to respond sensitively to climate variability and to integrate biological and physical perturbations over their decadal time-scale. One of the major challenges that we face when interpreting thermocline data is to distinguish between natural variability and long-term trends due to anthropogenic influences. In some cases observations now span multiple decades, allowing long-term trends to be distinguished from decadal variability, thus providing greater insight into the ultimate causes of change.
