Wave direction measurement and recording |
摘要 |
In the apparatus disclosed herein, a floating spar tethered at its midpoint is employed to determine wave direction. The balance of wave forces acting upon the spar tend to orient it parallel to passing surface wave fronts. A recording compass then determines and records the orientation of the spar.
