Seaports With Sea Level Change - 31

The Schooner 'Wyoming'
Probably enough has been said about this subject within the many posts on this issue here on Dredd Blog.

So I won't write much today about that history.

Instead you can peruse the subject matter in the previous posts presented as a public service over the years here on Dredd Blog (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).

However, too many tide gauge stations which inform us of sea level change are shutting down around the world.

So, I am working on new software that will blend the tide gauge stations data (PSMSL) with satellite data.

In the mean time, today I am adding another HTML table as the menu for checking up on what is happening to seaports around the globe:

(HTML) Single
Coastline Countries
(HTML) Multi
Coastline Countries
RLR-Coastline

Slc-Coastline

Appendix: P-TAppendix: P-TAppendix: P-TAppendix: P-T
Appendix: U-ZAppendix: U-ZAppendix: U-ZAppendix: U-Z

The appendices in the first two columns of the menu are alphabetical, based on the country name where the ports are located, and are HTML files with data about seaports and tide gauges related to those ports.

The appendices in the last two columns of the menu are alphabetical, based on the country name where the tide gauge stations are located, and are line-graphs of sea level changes in that area.

Wooden Ships

"If you smile at me, I will understand
that is something everybody everywhere
does in the same language

I can see by your coat, my friend, 
you're from the other side
There's just one thing I'd like to know
Can you tell me please, 
who won the war?

Say, can I have some of your purple berries?
Yes, I've been eating them
for six or seven weeks now
haven't got sick once
Probably keep us all alive

Wooden ships on the water, very free and easy
Easy, you know the way it's supposed to be
Silver people on the shoreline, let us be
Talkin' 'bout very free and easy

Horror grips us as we watch you die
All we can do is echo your anguished cries
Stare as all human feelings die
We are leaving, you don't need us

Go, take your sister, then, by the hand
Lead her away from this foreign land
Far away, where we might laugh again
We are leaving, you don't need us

And it's a fair wind
Blowin' warm 
out of the south over my shoulder
Guess I am going to
set a course and 
surely
go."

  1. I talked to an aging surfer at Ventura Beach, California the other day. He said he's been surfing the area for decades and he's never seen any sign of sea level change.
    He added that he'd also worked for an oil company on a drilling rig.

    He was a total climate change denier, all the way. He discounted hurricane Hilary, Maui wildfire and 100-degree ocean temps off Florida. Nah. Ain't happening, in his view.

    Perhaps conservative denial will save us???

  2. That area is in PSMSL Sea Coast number 823. The Santa Monica Pier (34.0008 Lat) is close to the same latitude as Ventura (34.16 Lat). The major ports and tide gauge stations are listed in the post under the heading "Country: United States, Coastal Id: 823 WOD Zone 7311" here: https://blogdredd.blogspot.com/2023/09/mul-apdx-u-z.html .

  3. The average SLR shown in the appendix for that area is "SLC: 1st yr (1971) 7,008.23 RLR --> final yr (2021) 7,276.47 RLR {+268.236 mm total}" which is about 10 1/2 inches. That has more impact than meets the eye "Our precious sand is disappearing right before our eyes. Up and down the California Coast erosion is already taking away our beach sand. Now scientists are predicting that between one-third to two-thirds of the beaches in Southern California will suffer such extreme erosion that they will be completely gone in the coming decades. In other words, THE RISING OCEAN will be slamming waves on cliffs and bluffs instead of rolling in and out on sandy beaches. Even the beaches that are not entirely gone could be much smaller and have little to no dry sand at higher tides." (emphasis added, Link)

  4. "Up to 70% of California beaches could disappear by end of the century" (The Guardian).
