Dynamics of Oceanic Motions
Abstract
LONG-TERM GOALS. This research is concerned with accurate and efficient four-dimensional field estimation and fundamental dynamical process studies for the mid-latitude ocean. The research is multiscale, interdisciplinary and generic. The methods are applicable to an arbitrary region of the coastal and/or deep ocean and across the shelf-break. Results contribute to: knowledge of realistic regional processes and general physical and physical/acoustical processes; and to the formulation and initiation of studies on physical-biological-chemical interactions essential to the understanding of biogeochemical-cycles and ecosystem dynamics. OBJECTIVES. General objectives are: (I) To determine for the coastal and/or coupled deep ocean the multiscale processes which occur: i) in the physical response to external and boundary forcings and via internal dynamical processes; ii) in the physical-biological-chemical interactions which control productivity and provide connectivity and isolation mechanisms for (sub) regional ecosystems; iii) in the physical-acoustical interactions which influence acoustic propagation and tomographic inversions. (II) To nowcast, forecast and simulate with data assimilation realistic oceanic fields with (sub) mesoscale resolution over large scale domains and to understand the essential dynamics controlling forecasts and regional predictability. Specific objectives include: i) Northwest Atlantic shelf seas studies with atmospheric and river flux; ii) Mediterranean studies in the Sicily Straits and the eastern basin; iii) extension and application of our balance of terms scheme (EVA) to multiscale, interdisciplinary fields with data assimilation; iv) extension and application of our hybrid ESSE data assimilation scheme to interdisciplinary fields and parameter estimation; and, v) regional predictability studies.
