The objective of the European Radar Ocean Sensing (EuroROSE) project is to
develop a radar based ocean monitoring system in support of safe navigation
in port approach areas and otherwise densely operated sea areas. Radar
measured data are assimilated into a fine gridded numerical model with
the aim of predicting, for a few hours, currents and waves. A demonstration
of this system was carried out off the North Spanish coast from October
to November 2000. The area selected covers the approach to the harbour
Two HF radars WERA (Wellen Radar) of the University of Hamburg were deployed.
WERA, operated at 27.65 MHz, measures surface currents within an area of
about 40 by 40 km with a spatial resolution of about 1 km and with a temporal
sampling of 20 min. The Spanish measurement network consists of different
types of wave bouys. Currents have not been recorded in the area under
consideration. For the first time, the maps of surface current, acquired
during the EuroROSE Gijon experiment, show the high spatial and temporal
variability off the North Spanish coast.
This paper presents first experimental results with emphasis on the dynamics
of the coastal current. Depending on the wind situation, up to two coastal
jets with a chain of eddies in between has been observed.
This work has been funded by the European Commision DG XII within the
MAST-3 programme, project EuroROSE, CT98-0168.
