CT34A:
The Behavior of Trace Elements and Isotopes in Different Ocean Basins: New Insights from Comparisons and Contrasts III Posters


Session ID#: 28118

Session Description:
Recent international programs such as GEOTRACES have been examining the biogeochemical cycling of trace elements and isotopes (TEIs) in the world’s oceans to reveal the mechanisms and rates affecting their concentrations, distributions, chemical forms, and interactions with organisms. In addition to studies by individual investigators, the accumulating results show many similarities, but some surprising differences between ocean basins, with a classic example being the regionally-specific Cd/PO4 relationships. In the same way that deviations from the Redfield ratio of N/P between ocean basins, known since the 1970s GEOSECS program, provide insight into nitrogen cycle processes, what can we learn from the comparisons and contrasts of TEIs, and what tools are needed to explore and test these observations? This session seeks presentations from the observational and modeling communities on lessons learned from inter basin TEI data sets with respect to inputs to, cycling within, and exports from the world’s oceans. In addition we invite contributions that consider how TEI distributions, their chemical speciation, and interactions with micro-organisms shape microbial community structure and productivity in various ocean basins.
