Advancing marine biogeochemical modeling through assimilation of data from autonomous ocean observing systems and paleoceanographic records

Taking advantage of recent advances in the development of autonomous ocean observing systems, ocean modeling and assimilation capabilities, and the availability of paleoceanographic proxies, the development of nested models of the North Atlantic continental shelf and deep ocean ecosystems, and of evolutionary models of Earth's biogeochemical cycles is proposed. These models are increasingly powerful tools that will prove necessary to gain an integrated and quantitative understanding of the dynamics and variability of marine ecosystems and biogeochemical cycles and their role in past and future climatic changes.
