PurposeResearch
ObjectivesThe major goal of the OMEX-II project is to gain a better understanding of the physical, chemical and biological processes at the shelf break, responsible for the exchange of matter and energy between the coastal zone and the open ocean. Emphasis however is on the carbon cycle.
It is the objective of the studies carried out during this cruise to contribute to understanding , definition, quantification and modelling of organic and inorganic particle transport and accumulation, of the diagenetic and burial processes and fluxes and the time scales involved in relation to the oceanographic conditions and benthic boundary layer dynamics along the shelf-slope-margin-abyssal plain transects across the Iberian Margin.
