# Mean Sea Level at Marii Pronchishevoi (Bukhta), Russia(NOAA 030-420, PSMSL 667)

display correctly. Try Google Chrome or Mozilla Firefox.

The mean sea level (MSL) trend at Marii Pronchishevoi (Bukhta), Russia is 0.00 mm/year with a 95% confidence interval of ± 0.00 mm/year, based on monthly mean sea level data from ???? to ????. That is equivalent to a change of 0.00 feet in 100 years. (R‑squared = (?))

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. By default, the long-term linear trend is also shown, in red, along with its 95% confidence interval. The plotted values are relative to the most recent Mean Sea Level datum established by NOAA CO-OPS.

Regressions
Linear:
y = B + M·x
y = B + M·x mm
y = B' + M·x + A·x²
y = B + M·x + A·x² mm
where:
Date range = (1935) to (2015)
x = (date - avg(date)(date)
slope = M = ± mm/yr
acceleration = 2·A = 2×A = ± mm/yr²
