DOI: 10.1002/2017jc012978
Abstract: Wave attenuation from two field experiments in the ice-covered Southern Ocean is examined. Instead of monotonically increasing with shorter waves, the measured apparent attenuation rate peaks at an intermediate wave period. This ‘rollover' phenomenon has… read more here.
