|Fig. 1 A pattern of evidence|
So, you and I can stop searching for the holy grail now.
That is because there is a more robust way to discern the fingerprint (FP) of sources of influences in tide gauge station records.
That was pointed out in the basic hypothesis set forth in yesterday's Dredd Blog post (SLC Fingerprints R Us).
The fundamental essence of the case is:
1) a land based ice source (ice sheet or glacier) melts or calves to release some part of itself from the land into the ocean;The number of tide gauge stations around the world were considered then condensed into the "golden twenty some odd" for specialized reasons (Fig. 1).
2) which increases the ocean's volume;
3) and diminishes that ice source's volume, mass, and gravitational power;
4a) the melt water / ice source's loss of gravitational power releases its grasp on sea water around it; 4b) the released melt water warms, the calved ice melts and then that melt water also warms;
5) the Earth's gravity, axial location, rotation, and ocean currents relocate all of the water released into the ocean realm;
6) tide gauge stations at or near the source, the terminus, and even along the way, will record that relocation as sea level change (SLC);
7) those tide gauge station records of SLC therefore contain evidence which can be used to determine the source or sources of that SLC.
It is possible that the following (still good) stations (still active) are some of those "golden twenty some odd" stations:
San Francisco (10)
Key West (188)
Aberdeen I (361)
North Shields (95)
Charleston I (234)
Hampton Roads (299)
Atlantic City (180)
New York (12)
So, today I will use the new Dredd Blog format for some of those "golden twenty something" stations to illustrate the point (Fig. 2).
|Fig. 2 Read this first.|
There are four graph sections to each full graph, the first section (upper left) is the combined totals (it is also the official PSMSL tide gauge station record for the station depicted).
The other three views or sections concern the contribution (in millimeters) that the ice sheets of "Antarctica" and "Greenland" make, as well as the contribution that glacial fields and ice caps on land make ("Glaciers").
The years involved in each view are displayed along the bottom of each graph.
Any one point in the three non-combined views adds up to that X-Y location's value in the combined view (top left graph):
You can see that displaying and quantifying the actual amounts for each SLC source is a robust way to deliver the information eh?
Each individual tide gauge station, not just a few, has the "DNA" to reveal the information using some simple algebra.
