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 andor deep ocean and across the shelf-break. Results contribute to knowledge of realistic regional processes and general physical and physicalacoustical 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 andor 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.
