This FWS description is adapted from the proposal.
This workshop is embedded within Axis 1 “The ocean engine at very high resolution” of the recently labelled Centre of Excellence named “LABEX MER” and located within the marine sciences campus in Brest (France). The ambition of this axis is to make major advances, over the next 10 years, in our understanding of the contribution of small scales to the dynamics of the ocean as well as the interactions of these small scales with larger scales. Designing and implementing an innovative field experiment to monitor small scales processes and their dynamics if one of the scientific targets of the axis.
Motivation to study the vertical exchanges of tracers associated with mesoscale eddies (with a diameter of 50-200km and depth extension of 500-1000m) is that the mean concentration of most oceanic tracers changes rapidly with depth. Because mesoscale processes may transport these tracers vertically, it has been hypothesized that these vertical exchanges may strongly affect not only the meridional heat fluxes (that impact the large-scale oceanic circulation, Ferrari and Wunsch, ARFM, 2009) but also the entire biogeochemical system and therefore the global tracer budgets (McGillicuddy, GBC, 2003) .
Design and implementation overview
Objective and programme outline
This workshop will be aimed to call for interest and aggregate the national and international community around the project and to assess the observing systems and strategies that are needed to achieve the project objectives. A first part will be devoted to scientific talks on processes (either physical, biogeochemical, biological) at fine scales in the ocean. A second part will be devoted to observing instrument or platforms dedicated to such oceanic scales. Lastly, the key scientific questions that need to be addressed by the new project and the final strategy of the field experiment will be discussed [including an implementation plan and a research proposal to be submitted to the national and international research funding agencies].
