Those 21-23+ stations are used by some sea level scientists to create a sea level change (SLC) "fingerprint" (Fig. 2).
The full list of those few stations could not be determined exactly, so today I offer the Dredd Blog Thumbprint (Fig. 1), a replacement of the lightweight "golden twenty some odd."

| Fig. 2The Golden Twenty Some Odd |
The Dredd Blog Thumbprint (DBT) is the "fingerprinting" of 487 tide gauge stations, or as I like to call it, "the most important digit".
The DBT is in the interest of all of the victims of the world who constantly hear "global mean average."
But, we victims of the world rarely, if ever, hear what "global mean average" means to us at our particular location on the good planet Earth (The Fingerprints of Victims Matter).

The red line is the global mean average of all 487 stations, which is a value of 7052 "RLR" millimeters (Revised Local Reference Definition).
I have placed some station numbers in rectangular boxes at some high and low points on the 487 tide gauge station locations on the graph (Fig. 1).
That is sufficient to get my point across, if you will note that Station #1593 is at 1036 mm, or 3.4 ft. above the global mean average (8088 - 7052 = 1036; 1036÷304.8 = 3.39895 ft. = 3.4 ft).

Then note that Station #563 is at 973 mm, or 3.2 ft below the global mean average (7052 - 6079 = 973; 973÷304.8 = 3.19225 = 3.2 ft.).
So, when most media figures and all too many scientists talk about the global mean average, it is meaningless to local people who do not realize the import of 1 m / 3 ft. on any sea ports near them (see Weekend Rebel Science Excursion - 44).
In the video below, Dr. Rignot points out how the scientific dialogue between scientists and non-scientists "really sucks," in terms of being effective at getting the dangerous message across.
Anyway, Fig. 3 and Fig. 4 are a modified view of the "Golden 487" stations of the new, and soon to be infamous, Dredd Blog Thumbprint series.
Notice that Fig. 3 has the perspective of "mean high sea level" of all those stations, without any low sea levels, that is, it is the average of the high sea levels experienced at each station for as long as that station has kept records.
Comparing that mean high to the "global mean average," we see that most stations have a mean high mark that is above the global mean average all of the time.
Ditto for Fig. 4, except that it is the mean low average for each station for as long as that station has kept records.
Again, comparing that mean average low to the "global mean average," we see that most stations have a mean low mark that is below the global mean average all of the time.
The status quo dialogue between science writers and the public is simply not a good way of doing scientific business with the public, as Dr. Rignot points out:
01:00 It may be a little bit of a shock to some people in [the scientific] community ...(Paraphrased from the video below). By the way, the Dredd Blog thumbprints all indicate that the melting ice which is threatening civilization all comes from one source: anthropogenic global warming induced SLC caused by burning dirty fossil fuels (Keep It In The Ground).
01:25 I think that the [scientific] community is very conservative [translation: always underestimating] with time scales.
01:40 the research shows that we are looking at timescales that are shorter than what past and current models depict
02:50 How do we communicate this to the public? I don't know, but we aren't doing a good job at that. I think most of the scientists are not trained for that ... I'm trying to learn ... I talked to people from the digital media and they say we [in the scientific community] really suck at it ... you are not doing it right.
