Description

Coastal and Estuarine Physical Oceanography

Research interests

I am interested in physical processes that influence three-dimensional transport in the coastal ocean as well as how this transport impacts marine ecosystems.  Circulation and transport processes on coastal shelves and in estuaries provide a pathway for mass property and material exchange, which can have a critical impact on the state of a marine system.  This is a challenging (but very interesting) region to study as a result of there being a broad scope of interacting forcing functions that operate on a wide range of temporal and spatial scales in conjunction with an irregular physical environment (i.e., bathymetry and coastal geography).  This results in complex flow fields.  As such, my research has focused on improving the understanding of the flow field and its associated response to forcing functions at a range of temporal and spatial scales.  By examining coastal ocean circulation, I hope to provide a more complete understanding of the processes that dictate the origin, fate, and residence time of material in the coastal ocean.  Another aspect of my research involves linking these physical processes to biological aspects of marine ecosystems.  As systems become more strongly influenced by anthropogenic impacts, identifying and understanding environmental controls over marine life cycles is essential to elucidating the inter-annual variability that characterizes biological systems.  Through my research efforts, I have also developed a keen awareness of the need to acquire high resolution data on estuarine and coastal physical processes due to the importance of these regions’ ecosystems and their relatively sensitive nature.  As such, coastal ocean observing systems provide a critical tool in the efforts of understanding the variability in these systems by providing unprecedented temporal and spatial views of coastal currents and hydrographic conditions.  The continued maintenance and expansion of these observing systems require both operational and scientific justification.  Thus, my research focuses on demonstrating new science based on the data provided from these observing systems.
