Seaports With Sea Level Change - 33

Fig. 1 Topex - Global Mean Sea level change

It has been awhile since I posted about sea ports and tide gauge stations (Seaports With Sea Level Change, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32).

As I said in a previous post, one reason I am adding satellite data to the tide gauge data is that some tide gauge stations are closing or being destroyed by changing governments, weather, and sea levels (Fig. 2).

The graph at Fig. 1 is an example of satellite data from NASA that has been collected for about three decades (Topex Posiden, Topex Poseidon Satellite Data).

Fig. 2 It's not just for Florida anymore

Note that the satellite data is not yet included in the data and that I am keeping the historical records (circa 1800 to now) of tide gauge stations from the PSMSL folks, just in case.

So, the tide gauge station records will still be included in the reporting going forward.

The three videos below, featuring Harvard professor Dr. Jerry Mitrovica, explain why we need to keep tide gauge records for as long as we possibly can.

The fact that sea level is rising and falling every day is acknowledged by oceanographers who are "in the know".

Among other things, this is shown by a graphic produced by a group of "in the know" scientists (Fig. 3). 

That is why Dredd Blog points out that scientific reality year after year (The Bathtub Model Doesn't Hold Water, 2, 3, 4, 5).

Appendices

Fig. 4 Extinction of Tide Gauge Stations?

Today's appendices contain both graphs and HTML tables, in alphabetical order according to the country names.

They feature RLR values but also contain millimeter values along with those RLR values.

That is done to help readers grasp what is being depicted more readily.

The graph at Fig. 4 tells a scary story which makes me wonder where in the world are all of the tide gauge reports going ... here is my SQL query that relates to the years 2013-2024:

mysql> select count(*) from rlrdata where year=2024...0
mysql> select count(*) from rlrdata where year=2023...97
mysql> select count(*) from rlrdata where year=2022...573
mysql> select count(*) from rlrdata where year=2021...649
mysql> select count(*) from rlrdata where year=2020...705
mysql> select count(*) from rlrdata where year=2019...714
mysql> select count(*) from rlrdata where year=2018...798
mysql> select count(*) from rlrdata where year=2017...820
mysql> select count(*) from rlrdata where year=2016...823
mysql> select count(*) from rlrdata where year=2015...843
mysql> select count(*) from rlrdata where year=2014...855
mysql> select count(*) from rlrdata where year=2013...874|

Could Fig. 2 be a clue (both sea level fall and sea level rise mandate expensive tide gauge station relocation or cessation)?
