Tide gauge records of uplift along the northern Pacific-North American plate boundary
[1] Vertical crustal motions at 15 sites along the northern Pacific-North America plate boundary are determined using relative sea level changes from tide gauge records. Our analysis is based on monthly mean sea levels, from which barometric pressure and seasonal effects are removed. The records are...

[1] Vertical crustal motions at 15 sites along the northern Pacific-North America plate boundary are determined using relative sea level changes from tide gauge records.

These records are statistically examined for non-linear behavior related to glacial isostatic, tectonic and postseismic effects. To estimate land uplift rates, the local effect of global sea level rise is removed from the relative sea level rates.
