Abstract: Yearly mean sea level series from 44 Coast and Geodetic Survey (U. S. Environmental Science Service Administration) tide stations are analyzed. An empirical classification is obtained from the relationship of series trend to yearly variability that uniquely groups specific geographical areas. The groups, together with their average trends for the longest common series, 1940 to 1962, are as follows: Northern Atlantic, 0.011 ft per yr; Southern Atlantic, 0.009 ft per yr; Pacific, 0.002 ft per yr; Gulf, 0.007 ft per yr; Southeast Alaska, -0.023 ft per yr. Significant changes in trend with time are not evident at the representative stations of New York since about 1950 and Fort Pulaski and Cedar Key since about 1953. The longest continuous series, New York, begins with 1893. The mean initial year for the 44 series is 1925.
