Tide Gauges & Mean Sea Level
Will The Real Sea Level Trend Please Stand Up !
In my continuing saga of sea levels, I thought that the work done by David Burton deserved its own post.
If anyone of you have been following my articles on Global Mean Sea Level (GMSL), I hope to bring even more nuggets of information your way.
David Burton has put together, probably the most comprehensive work regarding Mean Sea Levels.
You can view his website here.
Here is an partial image of his MSL Table page:
Pretty damn good work if you ask me.
The only thing I want to add, is a comment that I used as an update to my GMSL article here and as a comment at WUWT here.
David Burton already beat me to determining MSL, using existing tide gauges.
Thank goodness. It would have taken me months to do the calculations.
Though before we get our hopes up, RealClimate already ‘debunked‘ him, saying that his calculations are not peer-reviewed and doesn’t take into account GIA.
In regards to tide gauge mean sea level averages, what purpose does it serve to include an adjustment for GIA?(rhetorical)
Tide gauges are one dimensional readings though. Simply height.
GIA is about 3D volumetric displacement of land mass, due to uplift from ice sheet loss, and giving a value to correct a means for that displacement of land mass.
So while we’re at it, lets adjust for subduction, sinkage, sea wave erosion, lava buildup, island construction(my favorite), and any other phenomena that adjusts the height of any given tide gauge.
We can’t though, because each tide gauge is not effected by one or more phenomena that another tide gauge might be effected by.
That is why the GIA correction can only be applied to satellite altimetry data.
This only allows the alarmist community to confuse the issue, using convoluted models to support their propagandization.
The actual, physical observance of existing tide gauges the world over show only a 0.61 mm/year rise in the historical registry.
Which leads me to wonder where all that rise is hiding at.
If we don’t see any physical evidence at known tide gauge sites, then all the rise must be happening wherever man is not present.
Those 50 mile long, remote, uninhabitable beach fronts must be 10 feet under water right now.
