The monitoring was performed over the period from May 1983 through May 1984. It included the collection and analyzing of current, salinity, tide, wave, and beach and channel data. Evaluation of these data is discussed in detail." (from the Abstract) Gives a historical overview on work on the harbor up to the mid-1980s.},
