Monday, March 19, 2018. 12:00 PM. Webinar: Observations on the Ocean’s Mason-Dixon Line.  Mike Muglia, UNC Chapel Hill. Sponsored by NOAA National Ocean Service. More information here.


Abstract: Cape Hatteras, NC is the location of a complex confluence of ocean currents on the shelf, shelf slope, and near the abyss. The different water masses influence local weather and water temperatures at the beach, produce upwelling that supports an abundant fishery, and pose numerous scientific questions about current interactions, atmospheric stability, wind and marine hydrokinetic energy resources, and the Atlantic’s meridional overturning circulation. Mike will provide an overview of an extensive observing program off the North Carolina coast that is helping us understand this complex confluence of currents, and answer questions about the marine hydrokinetic energy resource potential off Cape Hatteras. Observations to be highlighted include: nested 13 MHz WERA and 5 MHz Codar HF radars, moored and vessel mounted 38, 75, 150, 300, and 600 kHz Acoustic Doppler Current Profilers, Slocum and Spray gliders, buoys, numerous CTD casts and moored time series, and several years of acoustic hydrophone recordings on the shelf slope.


About the Speaker: Mike Muglia helped found the UNC Coastal Studies Institute and leads CSI’s Gulf Stream resource assessment for the NC Ocean Energy Program. His scientific interests include understanding variability in position and transport of western boundary currents and the complex confluence of different shelf water masses, and meridional overturning circulation linkages between western boundary currents and deep western boundary currents. Specifics of my ongoing research efforts include: - Understanding high frequency variability in the cyclonic shear zone of the Gulf Stream with HF radars - Quantifying the variability in the available hydrokinetic energy resource from the Gulf Stream for the state of NC - Inferring Gulf Stream transport from HF radar surface current measurements - Gulf Stream, Mid Atlantic Bight, South Atlantic Bight, Chesapeake Bay Outflow, and Slope Sea water mass dynamics off of NC
