Related alphanumeric code for wave buoys is FM65 WAVEOB.
BUFR template used for wave buoys should be the same than for moored buoys (TM315008). GTS headers should start with character string 'IOB'.
It must be noted that another template for spectral wave data (TM308015) is under validation process. It should be used for other systems than moored buoys, including remote platforms (aircraft or satellite). GTS headers should start with character string 'IOW' in that case.
