Development and Testing of Embedded Gridding within the Regional Ocean Modeling System: Interactions Between Near-Shore and Off-Shore Currents and Materials

Abstract

The goals of this project are (1) to improve the algorithms for computational modeling of local oceanic regions that have significant interactions with their surrounding regions and (2) to simulate and understand the controlling processes for dynamical coupling and material exchanges between near-shore regions over continental shelves and adjacent off-shore regions over continental slopes and in deep water. The objectives of this project are (1) to continue the development of the Regional Oceanic Modeling System (ROMS) with respect to its hydrodynamic algorithms, physical transport parameterizations, and range of represented biogeochemical processes; (2) to further refine and apply its nesting capabilities using adaptive open-boundary conditions (OBCs) for imposing large-scale boundary data; (3) to develop a Multi-Grid embedding capability in ROMS for simultaneously calculating solutions on coarse-resolution (outer) and fine-resolution (inner) grids; (4) to use ROMS to investigate dynamical coupling and material transport between near-shore and off-shore regions along the North American West Coast (NAWC), with special attention to Monterey Bay, the Southern California Bight, and the GLOBEC NE Pacific region off Oregon and Northern California; and (5) to use ROMS to investigate the response of the NAWC region to remote forcing in the Pacific basin and the influence of NAWC coastal phenomena (e.g., upwelling) on Pacific basin-scale phenomena.
