Subject: Two special sessions at AGU/ASLO/TOS Ocean Sciences Meeting, February 20-24, 2006

We invite you to consider submitting papers to the AGU/ASLO/TOS Ocean Sciences Meeting, February 20-24, 2006. Please look at the following two Special Sessions:

Session Synopsis:
Oceanic variability that reaches well beyond observations of elevated temperatures is being attributed to anthropogenic climate change. This variability is manifest in the physics, chemistry, biology, and geology of the oceans. Increasing amounts of anthropogenic CO2 are being taken up by the oceans, reducing the pH and decreasing the degree of saturation of carbonate minerals. The amount of oxygen has been decreasing in some areas, and there are documented changes in ecosystem structures. Impacts of anthropogenic climate change vary significantly between oceans, and are particularly dramatic in high latitudes such as the Arctic and Antarctic Oceans. There are effects of fresh water from the melting of high latitude ice and increased evaporation in the tropics that has been accumulating in the North Atlantic Ocean. Papers are solicited for this multi-disciplinary symposium that present observations and model results of oceanic variability attributable to anthropogenic climate change, also projections of their possible effects and consequences for society.

Session Synopsis: The recent start of the CLIVAR/CO2 Repeat Hydrography Program in the U.S., and similar efforts in many other countries, which occur against the background of the successful completion of the WOCE/JGOFS global surveys in the 1990s, now permits scientists to examine decadal time-scale variations in the ocean in an unprecedented detail. This session invites contributions that approach such variations and changes from a many different angles, including but not limited to, physical, biological, biogeochemical and carbon cycle perspectives. We encourage submission of contributions that have made use of a broad palette of tools, i.e. including observational and modeling approaches. Particular emphasis will be placed on contributions that address ocean interior changes from an interdisciplinary perspective.
