Evaluating the surface circulation in the Ebro delta (northeastern Spain) with quality-controlled high-frequency radar measurements
2015
Ocean Science (OS)
Preserved Fulltext
The main goal of this work is to explore basic features of the sea surface circulation in the Ebro deltaic region as derived from reliable HF radar surface current measurements. ...
The accuracy assessment of radial and total vectors revealed a consistently high agreement. The directional accuracy of the HF radar was rated at better than 8°. ...
The authors gratefully acknowledge the Qualitas Remos Company (a partner of CODAR Ocean Sensors) for the useful suggestions, and deeply appreciate comments provided during the paper revision process by ...
