My research focuses on the physical mechanisms of exchange and stirring over the continental shelf, a critical aspect of our efforts to characterize the natural system present in the coastal ocean and evaluating the implications of changes in the system for stakeholders. While the dynamics that control wind-driven transport dominate exchange over the shelf as a whole, they can serve as a barrier over the inner part of the shelf, where surface and bottom boundary layers overlap and interact. In this unique environment, the scales of both vertical and horizontal stirring act to bound the across-shelf movement of particles. My research methods involve the use of in situ and remotely sensed observational systems, along with the application of idealized models, to expand our theoretical understanding of turbulent coastal flows and the processes that govern exchange.
Inner Shelf Lateral exchange (ISLE): A 3-year NSF-funded effort to examine the small scale O(100m to 10 km) spatial variability of the flow in the coastal ocean over the inner continental shelf south of Martha's Vineyard, MA.
The Role of Advective Heat Fluxes in Buffering Annual to Inter-Annual Temperature Variability Over U.S. Inner Shelves: This NSF-funded study, just underway, aims to understand the processes controlling water temperature variations over the inner shelf on annual and interannual timescales. Available temperature and velocity data sets will be used to examine how the heat balance can be maintained by a number of possible sources of cooling, including: across-shelf exchange due to depth-dependent upwelling, the along-shelf advection of an along- shelf temperature gradient, and the across-shelf exchange due to eddies. The results will be synthesized to determine the relative contributions of heat flux components and their associated processes for the different shelf regions of the continental U.S., how the dominant processes vary over the annual cycle, and their implications. We are currently looking for a student to participant in this project.
HF Radar data processing and products: I am participating in ongoing work to develop and refine new methods to process HF radar backscatter towards the goal of lower error, higher resolution remote sensing of the surface currents of the coastal ocean. Additionally, I am interested in developing new products from the core radar observations, such as surface wind and wave estimates.
