A comparison of the harmonic contents of the tides (Table I) shows that the M2 

 component at Aruba precedes that at Zapara Island by 123° or more than one-quarter 

 period. High water occurs at Las Piedras only one-half hour earlier than at Zaparita 

 Island, and 1 -3 hours earlier than at Zapara Island. These relations place the antinode
