|Fig. 1 Sea Level Zones|
Well Pilgrims, I found another database source (Woohoo ain't we got fun).
Since my worry about SLC destroying the sea ports of the world is growing, I delved into tide-gauge databases.
If you want to, you can blame Professor Dr. Jerry X. Mitrovica and his student Natayla Gomez, who is now also a professor.
But, if you are real, you won't blame them, instead, you will send them a thank-you card.
They got game.
II. The New Data
Anyway, I downloaded data from Permanent Service for Mean Sea Level (PSMSL), a very reputable source:
Established in 1933, the Permanent Service for Mean Sea Level (PSMSL) has been responsible for the collection, publication, analysis and interpretation of sea level data from the global network of tide gauges. It is based in Liverpool at the National Oceanography Centre (NOC), which is a component of the UK Natural Environment Research Council (NERC).(About PSMSL). That download is only the beginning of it, not the end of it, because then comes the software design and coding to handle it.
III. New Programs
Next I wrote C++ programs that parsed all of that flat-file structure-format data, so as to automatically put it into an SQL database (mySQL) as per usual.
I named the database "PSMSL" in honor of the hosts of the data.
Currently, there are three tables, "rlrdata", "stations", and "test".
The "stations" table has all the relevant tide-gauge data from around the world.
There are 1,417 tide-gauge station descriptions from around the globe.
Two of the columns or fields in the stations table are "latitude" and "longitude."
Those two allow the software to 1) identify each station as being within a zone, and 2) identify an ice sheet source as an impactor on that zone.
Thus, when relevant SLC (whether SLF or SLR) takes place in that zone, I can look to the source ice sheet to find out if there were visible dynamics such as calving (The Evolution of Models - 12) or melt.
The GRACE satellite detects either one of those phenomena, because loss of ice to melt or to calving means loss of gravity where the loss took place.
IV. SLC Fingerprint Zones
As you can see in Fig. 1, there are various coastal locations on the globe that are impacted characteristically when land ice in Greenland, Antarctica, and/or non-Polar glacial zones, individually and/or collectively, makes its way to the sea.
The link @ Fig. 1 is to a paper by Mitrovica, Gomez et al. which details the science of the issues.
Have a good labor day next year.
Will share more about all of this in the days ahead.
