Systematic improvements in algorithmic design of regional ocean circulation models have led to significant enhancement in simulation ability across a wide range of space/time scales and marine system types. As an example, we briefly review the Regional Ocean Modeling System, a member of a general class of three-dimensional, free-surface, terrain-following(More)
[1] The biogeochemistry of continental shelf systems plays an important role in the global elemental cycling of nitrogen and carbon, but remains poorly quantified. We have developed a high-resolution physical-biological model for the U.S. east coast continental shelf and adjacent deep ocean that is nested within a basin-wide North Atlantic circulation model(More)
[1] The contribution of coastal oceans to the global air-sea CO 2 flux is poorly quantified due to insufficient availability of observations and inherent variability of physical, biological and chemical processes. We present simulated air-sea CO 2 fluxes from a high-resolution biogeochemical model for the North American east coast continental shelves, a(More)
[1] It has been suggested that continental shelf systems contribute disproportionately to the oceanic uptake of atmospheric CO 2 , but the magnitude of this flux and the relative contributions of different underlying mechanisms are poorly quantified. A biological continental shelf pump mechanism has been implied; however, the magnitude of this export(More)
[1] Continental shelf systems are thought to play an important role in the exchange of carbon dioxide (CO 2) between the atmosphere and ocean. Currently, our ability to quantify the air-sea flux of CO 2 on continental shelves is limited due to large spatial and temporal variability coupled with historically sparse oceanographic measurements (e.g., of(More)
Continental margin systems are important contributors to global nutrient and carbon budgets. Effort is needed to quantify this contribution and how it will be modified under changing patterns of climate and land use. Coupled models will be used to provide projections of future states of continental margin systems. Thus, it is appropriate to consider the(More)
A new model based insight into the couple of nitrogen and cryptic sulfur cycles in a coastal upwelling systems. This supplemental material contains figures describing 1) cross-shore section of initial and boundary values of temperature, salinity, alongshore current, oxygen, nitrate, and phosphate used in the model and 2) cross-shore section of ammonium(More)
Why a chapter on Perspectives and Integration in SOLAS Science in this book? SOLAS science by its nature deals with interactions that occur: across a wide spectrum of time and space scales, involve gases and particles, between the ocean and the atmosphere, across many disciplines including chemistry, biology, optics, physics, mathematics, computing,(More)
