Physical and biogeochemical ocean dynamics can be intermittent and highly variable, and involve interactions on multiple scales. In general, the oceanic fields, processes and interactions that matter thus vary in time and space. For efficient forecasting, the structures and parameters of models must evolve and respond dynamically to new data injected into(More)

Executive Summary Under contract with Massachusetts Water Resources Authority, the University of Massachusetts Dartmouth's Marine Ecosystem Dynamic Modeling team conducted model simulations for the Massachusetts Bay system. These models simulate the water motion (hydrodynamics) and the biologically-driven changes in carbon and nutrients (water quality) of(More)
The next challenge for MIMO radio channel models is to simulate the time-variant nature of the channel correctly. Cluster-based MIMO channel models are well suited for this problem, however they currently lack an accurate pa-rameterization of the time-variant cluster parameters. In this paper we identify and track clusters from three different measurements(More)
