On The More Robust Sea Level Computation Techniques - 9

Tight Rope
I mentioned a while back that "In Tamisiea & Mitrovica scientists pointed out that bottom pressure gauges, not limited to coastlines, would be a valid source for detecting sea level changes accurately" (Very Breezy).

That they considered bottom pressure records to be the better way of determining sea level rise in the deep ocean far from tide gauge stations on the coasts was enough to get me going.

Next came a read of (mbars to sea level and 2008 and 2011).

Twenty some million rows later (in the new bottom pressure SQL database) and we are going to check that all out closely because it is the more robust way to keep an eye on that area (On The More Robust Sea Level Computation Techniques, 2, 3, 4, 5, 6, 7, 8).

You know that using the better ways leads to the better results.

The curve ball thrown at anyone attempting this bottom-pressure data-records collection feat is that the data formats vary to a significant degree.

I like the WOD format for bottom pressure records, but it is at variance with the other sources of records.

So, it takes a lot longer to build twenty million (plus) records, because they have to be merged in this case.

Anyway, another "forging forward" promises to bring yet another new tool into our toolbox.

In this case, we aren't about changing reality, we are about observing it with as much accuracy as possible.

  1. I seriously love your site.. Very nice colors & theme. Did you create
    this website yourself? Please reply back as I'm attempting to create my very own website and would
    like to learn where you got this from or exactly what the theme is called.
