EXPERIMENTAL-METHOD TO MEASURE SURFACE SIGNATURE GENERATION BY SEA BOTTOM UNDULATIONS

An experimental method to investigate submarine bedform signatures at the sea surface is described. The study area was the Lister Tief in th e German Bight of the southeastern North Sea, a semienclosed tidal bas in with asymmetric and very large sand waves. In-situ and remote measu rements of surface roughness were obtained simultaneously. An X-band w ave monitoring radar, an oceanographic multisensor sea surface buoy, a n acoustic Doppler current profiler, and a standard echo sounder were operated on and from board a research vessel while drifting along the tidal channel.
