Mean Sea Level Trends for Northern Atlantic Stations

The graphs compare the 95% confidence intervals of the mean sea level trends. Trends with the narrowest confidence intervals are based on the longest data sets. Trends with the widest confidence intervals are based on only 30-40 years of data. The graphs give an indication of the differing rates of vertical land motion, given that the absolute global sea level rise is believed to be 1.7-1.8 millimeters/year. The calculated trends for all stations are available as a table in millimeters/year and in feet/century
