Seaports With Sea Level Change - 3

Seacoasts Aplenty

The Permanent Service for Mean Sea Level (PSMSL) has updated its database since the last post of this series, so I am updating the series.

I am posting two sets of appendices, one covering single-coastline countries that have both seaports and tide gauge stations, the other covering multi-coastline countries that also have both seaports and tide gauge stations.

The PSMSL categorizes coastlines based on ocean characteristics, such as being an Atlantic Ocean coastline or being a Pacific Ocean coastline.

Some countries have half a dozen coastline codes or so, and on down to only one coastline code for a number of countries.

The links in the table below are organized accordingly.

Links to Appendices

Single-Coastline Countries	Multi-Coastline Countries
Appendix: A - C	Appendix: A - C
Appendix: D - G	Appendix: D - G
Appendix: H - L	Appendix: H - L
Appendix: M - O	Appendix: M - O
Appendix: P - T	Appendix: P - T
Appendix: U - Z	Appendix: U -Z

Another reason for this post is to update the discussion about the location or source of sea level rise (SLR) and sea level fall (SLF) at ports and tide gauge stations.

There are no graphs associated with today's appendices, but you can review relevant graphs in previous posts of this series.

A recent paper indicates that earlier Dredd Blog series are on to something:

"How fast does warm ocean water melt glaciers that terminate in the sea? That question is central to understanding how fast ice sheets may lose mass, and thus how fast sea level will rise, in response to global warming, but there are few data about the process. Sutherland et al. used repeat multibeam sonar surveys to observe an Alaskan subsurface tidewater glacier face to create a time series of its melting and calving patterns. They observed melt rates up to a hundred times larger than those predicted by theory, observations that compel us to reevaluate predictions of such ice loss."

(Science Mag, emphasis added, cf. Phys. Org., Science Daily). The Dredd Blog series I mentioned are (The Ghost Plumes, 2, 3, 4, 5, 6, 7, 8, 9), and (The Ghost Photons, 2, 3).

Seaports will be impacted by any acceleration of melting and/or calving, so this post gives an indication of how much impact might be expected.
