Golden Gate Tidal Measurements: 1854-1978

Abstract

The recent discovery of leveling connections between the bench marks of the tide stations at Fort Point Sausalito, and the Presidio, San Francisco, California, between 1954 and the present, provide a continuous set of tidal measurements in the Golden Gate area. This is the only location in the United States with over 100 yr of continuous tidal measurements. Such a long series of tidal measurements are important in global sea level analysis, variability of water level relative to land over long periods and historical tidal boundary determination.
