PurposeResearch
Objectives1. To study the role of biogeochemical and hydrographic processes in controlling the distribution of dissolved trace metals in the shelf break region and adjacent waters, with due regard to temporal variability.
2. To estimate fluxes across trace metal fronts in the shelf break region and evaluate the use of trace metals as tracers of advective exchanges of waters at the shelf break.
3. Based on these and other OMEX data, to further the development of models for frontal exchange of dissolved trace metals and the linking of these models to a shelf seawater quality model.
4. In addition to the trace metal work, to collect other information and samples relevant to the aims of the OMEX project.
