  1. Synthesize available information on important EBUS processes, their time and space scales (i.e., diurnal, intraseasonal, interannual, decadal, multidecadal) and their implications on water column properties, biogeochemical cycles, biodiversity/ecosystem structure and functioning, and the ecosystem services they provide. Seek to identify key feedback mechanisms, establish similarities, differences and knowledge gaps across all EBUS.

  2. Develop a Web portal for EBUS by creating a Web-based platform to graphically query integrated information on published data, model outputs, as well as protocols for measuring key properties and indicators in EBUS.

  3. Determine the strengths and weaknesses of existing EBUS coupled physical-biological models. Such an analysis will have mostly a regional focus, but it will also attempt to address subregional scales building upon past and on-going research programs on upwelling centers (e.g. Bay of Hann near Dakar (Senegal), Monterey Bay (USA), Bay of Concepcion (Chile)).

  4. Recommend a framework for regional interdisciplinary (physics to biology) EBUS observing and modeling systems. This stems from TORs 1-3.
