chart: Mean Sea Level Trend, 822-071 - Vancouver, Canada
The mean sea level trend is 0.37 millimeters/year with a 95% confidence interval of +/- 0.23 mm/yr based on monthly mean sea level data from 1910 to 2011 which is equivalent to a change of 0.12 feet in 100 years.

[Potentially anomalous data from January 1940 to December 1941 has been removed from analysis]

Source Data & Additional Metadata

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 or a table 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.
