The Extinction of Robust Sea Ports - 11

I. Begin Here

This series has not been written for the tree huggers, polar bear huggers, or the like (The TH).

It has been written for the container ship huggers, the flag huggers, and the like (The CH).

The CH

II. The Common Bond

The "common bond" between The TH and The CH is that what they hug is going extinct.

The "distinction" between The TH and The CH is that The CH created their own extinction scenario while making fun of The TH extinction scenario.

III. Review

There isn't much to review about The TH because they have been made famous by the trolling done on them by The CH, however, some readers will need to become more acquainted with the world of The CH.

IV. Top Ten Sea Ports of The CH

According to one of The CH (Who They?) the top ten seaports are:

10. Port of Tianjin
9. Port of Dubai
8. Port of Qingdao
7. Port of Guangzhou
6. Port of Busan
5. Port of Hong Kong
4. Port of Ningbo-Zhoushan
3. Port of Shenzhen
2. Port of Singapore
1. Port of Shanghai

(ArcBest Holdings LLC). According to The World Ocean Database, this means that the WOD Zones where those top ten seaports are located, are as follows:

1010 (Singapore)
1205 (Dubai)
1211 (Hong Kong, Shenzhen, Guangzhou)
1212 (Ningbo-Zhoushan)
1311 (Qingdao,Tianjin)
1312 (Shanghai, Busan)

(World Ocean Database). A recent Dredd Blog post produced PSMSL tide gauge records and graphs using those PSMSL records concerning those and other zones (Countries With Sea Level Change - 5).

The relevant zones numbers for the top ten seaports above are in highlighted in red below:

III. Closing Comments

Most of the top ten are in only a few WOD Zones that are not far apart, and in fact they even border one another in some cases.

That means a common area impacted by the same SLC dynamics.

I wrote above that "some readers will need become more acquainted with the world of The CH", so here is a list of posts to read, which is a good way to do that (The Extinction of Robust Sea Ports, 2, 3, 4, 5, 6, 7, 8, 9, 10).

The Antarctica and Greenland Ice Sheet mass loss has increased six fold in recent decades (Forty-six years of Greenland Ice Sheet mass balance from 1972 to 2018, Four decades of Antarctic Ice Sheet mass balance from 1979–2017).

Countries With Sea Level Change - 5

From Wikimedia Commons

I. Background

The previous post of this series dealt with countries with multiple PSMSL coastline codes.

This post today deals with the remaining countries that have only one PSMSL coastline code.

China, for example, has only one PSMSL coastline code, even though it is a giant of a country.

So, to be thorough, I thought this post would tidy up a bit.

II. Appendices Galore

There are two types of appendices today.

The first is an HTML based display of the comparison between tide gauge sea level change (SLC) records and TEOS-10, i.e. Gibbs-SeaWater (GSW) Oceanographic Toolbox, calculated thermosteric volume change (tsSlc) which impacts upon SLC.

Those appendices are linked to in the first column ("Tide Gauge Data and Thermosteric Data") below in Section III.

The second set of appendices are linked to in the second column ("DNA" Graphs) below in Section III.

The second set is a graph of the "DNA" of SLC in the countries featured in the first set of appendices.

Thus, there is a comparison between the major SLC factor (ice melting) and the minor SLC factor (ocean warming induced ocean volume change), as well as a graph of the attributes of SLC which are sea level fall (SLF) and sea level rise (SLR).

III. Links to Appendices

Tide Gauge Data and Thermosteric Data	"DNA" Graphs
Countries: A - C	A - C
Countries: D - G	D - G
Countries: H - L	H - L
Countries: M - O	M - O
Countries: P - T	P - T
Countries: U - Y	U - Y

IV. Closing Comments

The first set of appendices have an explanation of their contents.

It is located at the top of each appendix.

The second set are graphs a la Beyond Fingerprints: Sea Level DNA - 3 except that today's graphs, as I wrote above, are graphs of SLC in countries with only one coastline code.

The number of coastline codes, as you will see, gives no indication of the size of a country.

Small countries can have more coastline codes than large countries, and vice versa.

That is why I think PSMSL made the coastline code system based on characteristics of the coastlines.

Anyway, there is a lot of interesting information in the graphs, which as usual are presented as a public service of Dredd Blog.

Appendix P-T To Countries - 5

This file is an Appendix to: Countries With Sea Level Change - 5

This file presents the thermosteric sea level change (tsSlc)
as well as in situ measured sea level change (SLC) caused by
the melting and calving of glaciers and ice sheets.

Records are obtained from two sources:

1) PSMSL (ground-based coastal tide gauge data)
2) WOD (seawater in situ measurements at various depths).

Calculations of thermosteric volume change in ocean water
is calculated with the TEOS-10 software toolkit.

The span of years within which the records were obtained
has been synchronized for equal calculation results (The
SLC and TeSlc beginning and ending years are the same).

A millimeters-per-year value is also calculated to give
a better understanding of the impact that ocean heat content
has on the ocean's volume, compared to the impact that
melting ice and glacial calving has on the ocean's mass.

Both cause SLC, but the thermosteric component is minor.

Graphs of the countries featured below are here.
