Remote Sensing of Surface Currents Associated with the Chesapeake Bay Outfall Plume Using a Shore-Based HF Radar

摘要

The long-term goal is to understand the dynamics and temporal and spatial variability of the dynamics of the outflow plume and its subsequent transition to a coastal jet using the combination of VHF/HF radar observations as well as additional moored, shipborne and remotely sensed data. Scientific objectives are: 1. To characterize the space/time scales of the outflow plume variability embedded within a mesoscale flow regime. 2. To interrelate remotely- sensed signatures from OSCR/INSAR/Ship radar measurements by examining the salinity front and buoyant jet trapped against the coast. 3. To estimate horizontal advection, shear and vorticity associated with the mean and tidal flows. 4. To assess horizontal mixing effects between the fresh water from the outflow plume and the coastal ocean through the interaction of various current components.
