| A surface current field (arrows) measured by the HF radars at Petten and Voordijk with colour-coded depths in the background. A coastal jet can be observed, which can be interpreted as part of the "coastal river" due to fresh water input into the North Sea mainly by the Rhine River. This water is transported along the Dutch coast to the north by the residual current. The red arrows are in regions where interference affected the radar measurements at the Petten site. The three red stars indicate the positions of directional waverider bouys, which will be used to evaluate the WERA wave measurements. |
