CT24A:
The Role of Particles in the Cycling of Trace Elements and Their Isotopes in the Ocean III Posters

Submit an Abstract to this Session

Session ID#: 7493

Session Description:
A number of trace metals are thought to control marine ecosystem features and biological productivity. While trace elements in the dissolved phase have been the focus of many investigations, we are still largely ignorant of the large scale distribution of particulate trace elements and their size partitioning and chemical composition. The GEOTRACES program, which aims to provide a comprehensive view of the distribution of trace elements and their isotopes (TEIs) in the world's oceans, is providing new insights on these aspects. Furthermore, there is a crucial need to understand the exchange mechanisms between particulate and dissolved pools, including adsorption, desorption, aggregation, precipitation, biological uptake and remineralization processes.  This session seeks to bring together scientists interested in better constraining the role of ocean particles in the biogeochemical cycles of TEIs, in different oceanic environments, such as the continental shelves and slopes, the nepheloid layers, or the particle-poor regions of the open ocean. We invite abstracts on all aspects of oceanic particulate TEIs, through experimental, in situ and modeling approaches.
