Permanent Service For Mean Sea Level (Update)

Tide gauge records updated

The PSMSL folks updated their database on or about May 8th.

So, I downloaded the new monthly and annual datasets, then merged them into my SQL system.

I thought it might be time to distance this Dredd Blog post from the mean average realm, so, here are the ten highest and lowest RLR measurements in the new dataset (no mean averages today!).

A link to each tide gauge station in the high/low list is also provided.

Highs:

rlrMM = 8216.25 (1216.25mm; 3.99032 ft.) above median 7000mm

For those thirsty for the mean average, it is 7002.02 mm for the above figures ("The oceans have risen 2.02 mm folks, move along nothing to see here").

The "7000 mm median" and "RLR" are explained here.
