    Henderson, Stephen M.; Guza, R. T.; Elgar, Steve; Herbers, T. H. C. (American Meteorological Society, 2006-04)
    Previous field observations indicate that the directional spread of swell-frequency (nominally 0.1 Hz) surface gravity waves increases during shoreward propagation across the surf zone. This directional broadening contrasts ...
