Marine ecosystems are characterized by complex trophic interactions that occur on disparate time and space scales. Modulation by physical and biogeochemical properties further complicates these interactions. To date, most studies of marine ecosystems consider shelf and open ocean regions separately. However, through active migration and/or advective processes, shelf and oceanic populations are coupled. In this session, we welcome modeling contributions that consider shelf, open ocean and coupled shelf-ocean domains that integrate across multiple spatial scales, temporal scales and trophic levels. From these studies we seek to develop a better understanding of how open ocean and shelf ecosystems are linked.
