EC44B:
New Insights in Coastal Oceanography from High-Frequency Radar Observations Posters


Session ID#: 9568

Session Description:
Over recent decades, high-frequency radar has become commonplace in observing surface circulation in coastal waters.  With hourly data and land-based operation that can be maintained continuously for years, this technology provides new insights in coastal oceanography.  At several sites, records of surface circulation have been continued for over a decade, providing new information on interannual variability.  Further, networks of radars provide continuous coverage over hundreds of kilometers of coastline and up to 200km offshore. California invested significantly in HF radar technology by establishing a statewide network 10 years ago.  With the maturing of this technology, attention has turned to what we can learn from HF radar data. These data have been assimilated in numerical models and used in operational systems including search and rescue and oil-spill response. Studies along the California coastline and around the world have produced new insights that could not have been generated without HF-radar observations.  The data have also been invaluable in education, enabling visualization of surface circulation in coastal waters. This session seeks contributions that address transport patterns resolved by these data, including physical oceanographic studies that explain flow patterns and biological/chemical oceanography studies that address  transport in key ecological and environmental questions.
