An extensive network of high frequency radars observes and
maps surface currents in U.S. coastal waters. This network provides
valuable data for use in near real-time applications such as search and
rescue and oil spill response while maintaining a long-term public data
record that is available for scientific research. ODU operates five radar
stations in Virginia and Maryland; two of these sites are located in the
lower Chesapeake Bay and three are located on the Atlantic coast. The
individual antenna stations produce hourly radial data which are combined
into a gridded total vector product and posted online for public access.
This presentation will provide an introduction to high frequency radar
technology and then take a closer look at the lower Chesapeake Bay radar
currents record. An analysis of the multi-year record yields an improved
knowledge of average spatial patterns and variability in the tidal and
non-tidal components of surface flow.
Teresa Updyke is a research associate at CCPO. She has worked with Dr. Larry Atkinson and the coastal ocean radar systems since 2007. An an active member of the radar operator community, she works on data quality and management issues at regional and national levels. She received a Master's of Oceanography degree from ODU under the advisement of Dr. Ann Gargett and she holds a B.S. in Earth & Atmospheric Sciences from Georgia Tech. As a graduate student, she helped develop a method to estimate vertical overturning length scales from CTD profile data. She was first introduced to the field of oceanography, and more specifically, the analysis of tides and currents in estuarine environments, through work opportunities at the Skidaway Institute of Oceanography and with NOAA's Center for Operational Oceanographic Products & Services.
