Mean Sea Level Trend
190-091 Brest, France

The mean sea level trend is 1.05 millimeters/year with a 95% confidence
interval of +/- 0.08 mm/yr based on monthly mean sea level data from
1807 to 2011 which is equivalent to a change of 0.34 feet in 100 years.

[Metadata: Data for 1807-1835 are monthly mean tide level]

The plot shows the monthly mean sea level without the regular seasonal fluctuations due to coastal ocean temperatures, salinities, winds, atmospheric pressures, and ocean currents. The long-term linear trend is also shown, including its 95% confidence interval. The plotted values are relative to the most recent Mean Sea Level datum established by CO-OPS. The calculated trends for all stations are available as a table in millimeters/year and in feet/century (0.3 meters = 1 foot).

If present, solid vertical lines indicate times of any major earthquakes in the vicinity of the station and dashed vertical lines bracket any periods of questionable data or datum shift.
