Sea level - 100 years on.

The sea wall at Anthony's Nose
is 100 years old.

The wall is at the bottom of the cliff face from the Arthur's Seat
mount.

The sea wall was one of the many projects in southern Victoria
to employ soldiers who returned from the First World War.

Today is June 21 - The Winter Solstice.
In spite of the "sol" - sun in the word
It is really part of the lunar cycle and calendar.

So at about 2.30 pm today was high tide (springs)
Springs and neaps are about a fortnight apart
Reference Tide Charts for mariners
by the Victorian Channel Authority.

The sea wall was erected on the high water springs level 100 years ago.

This is the end of the wall looking south - date today 21/06/2020. Note it is maximum high tide and there is only a little beach exposed.

The photo clearly shows the waters of Port Phillip Bay lapping the bottom of the Anthony's Nose sea wall;
exactly at high tide (springs) at the exact place 100 years after the wall was built.

The end of the wall built by returned soldiers from WW1

It is clear from the date and tide and position of the 100 year old wall
that the sea level is exactly the same as 100 years ago.

There is a tide gauge in Sydney Harbour
which was installed in 1914
It is directly linked to the Pacific Ocean
and while there are variations due to celestial object and weather
The sea level today is much the same as 1914.
